|
Funding: Work supported by the U.S. Department of Energy. In recent years, control system efforts at LAMPF have emphasized the provision of uniform control for the LAMPF linear accelerator and associated beam lines and the Proton Storage Ring and its associated beam lines. The situation is complicated by the presence of several control philosophies in the operator interfaces, data base mechanisms, and front end data acquisition and control interfaces. This paper describes the current system configuration, including the distributed operator interfaces, the data and control sharing between systems, and the use of common accelerator diagnostic software tools. Successes as well as deficiencies of the present system will be discussed with an eye toward future developments. |

| S01SRA05 | Process Control for the Vivitron: the Generator Test Set-up | controls, real-time, high-voltage, data-acquisition | 19 |
|
|||
| The VIVITRON is a 35 MV Van de Graaff tandem electrostatic accelerator under construction at the CRN since 1985. About half of the parameters are controlled by equipments which are highly stressed by their physical environment: sparks, electrostatic field, X-rays, vacuum, and gas pressure. It needs a dedicated process control system. The described control system is used since early 1991 to perform the voltage tests of the generator. It provides important information for the accelerator tuning and for the full size control under development. | |||

| S01SRA07 | The GSI Control System | controls, operation, software, status | 27 |
|
|||
| The GSI accelerator facility consists of an old linac and two modern machines, a synchrotron and a storage ring. It is operated from one control room. Only three operators at a time have to keep it running with only little assistance from machine specialists in daytime. So the control tools must provide a high degree of abstraction and modeling to relieve the operators from details on the device level. The program structures to achieve this are described in this paper. A coarse overview of the control architecture is given. | |||

| S01SRA11 | The Control System of HIRFL | controls, status, heavy-ion, experiment | 44 |
|
|||
| The Heavy Ion Research Facility in Lanzhou (HIRFL) is a multi-purpose and variable energy machine designed to accelerate wide range of ions. In order to obtain a designed beam (particle and energy) and to transport it to a proper experimental areas in a short time requires to modify a great number of parameters, this cannot be easily achieved without the help of a computer. The control system design and construction was started in 1983. First of all, some local control station of accelerator subsystems were finished in 1988 and satisfied the needs of operating and commissioning at the elementary level. Controlling the HIRFL process is implementing at a high level. | |||

| S01SRA12 | Control System for a Heavy-Ion Accelerator Complex K4 - K10 | controls, real-time, software, hardware | 47 |
|
|||
| Control systems for newly created accelerators, perhaps for the first time, may be designed almost only around international standards for communication and control techniques. This is also true for the project of a control system for the accelerator complex K4-K10 at the Joint Institute for Nuclear Research Dubna. Nevertheless, open systems architecture with construction principles being essential for modem systems of such big devices as particle accelerators leaves designers enough possibilities for solving even very sophisticated problems. | |||

| S02SRU01 | Future Directions in Controlling the LAMPF-PSR Accelerator Complex at Los Alamos National Laboratory | controls, software, hardware, network | 50 |
|
|||
|
Funding: Work supported by the US Department of Energy. Four interrelated projects are underway whose purpose is to migrate the LAMPF-PSR Accelerator Complex control systems to a system with a common set of hardware and software components. Project goals address problems in performance, maintenance and growth potential. Front-end hardware, operator interface hardware and software, computer systems, network systems and data system software are being simultaneously upgraded as part of these efforts. The efforts are being coordinated to provide for a smooth and timely migration to a client-server model-based data acquisition and control system. An increased use of distributed intelligence at both the front-end and the operator interface is a key element of the projects. |

| S02SRU02 | Common Control System for the CERN Accelerators | controls, software, network, operation | 54 |
|
|||
| The PS and SPS Accelerator Control Systems are becoming obsolete and need urgent rejuvenation. After a control users forum, where users expressed their needs, two main Working Groups were set up, consisting of Control and Equipment Specialists and experienced Machine Operators. One Working Group studied the architecture and the front-end processing and the other a common approach to the application software needed to run the CERN accelerator complex. The paper presents the technical conclusions of their work and the policy to implement it, taking into account the necessity to operate both machines without interruption of the Physics Program. | |||

| S02SRU03 | New Control Architecture for the SPS Accelerator at CERN | controls, network, real-time, software | 59 |
|
|||
| The Control System for the 450 GeV proton accelerator SPS at CERN was conceived and implemented some 18 years ago. The 16 Bit minicomputers with their proprietary operating system and interconnection with a dedicated network do not permit the use of modern workstations, international communication standards and industrial software packages. The upgrading of the system has therefore become necessary. After a short review of the history and the current state of the SPS control system, the paper describes how CERN’s new control architecture, which will be common to all accelerators, will be realized at the SPS. The migration path ensuring a smooth transition to the final system is outlined. Once the SPS upgrade is complete and following some enhancements to the LEP control system, the operator in the SPS/LEP control center will be working in a single uniform control environment. | |||

| S02SRU06 | Upgrading the Control System for the Accelerators at The Svedberg Laboratory | controls, cyclotron, hardware, software | 78 |
|
|||
| Two accelerators at The Svedberg Laboratory in Uppsala, the Gustaf Werner cyclotron and the CELSIUS ring, will get a new control system. At present both the cyclotron and the ring have their own control systems based on S99 and PDP11 minicomputers respectively. There are also a number of subsystems which are controlled separately from the standalone PC based consoles (ECR ion source, electron cooler, vacuum system). The goal of the rejuvenation is to integrate all existing control systems and provide the new system with an uniform operators interface based on workstations. The obsolete S99 microcomputers will be substituted with a VME system and all subsystems will be connected to the Ethernet. The upgrade strategy enabling the transformation of the system without any long shut-down period is discussed. Hardware and software planned for the upgrade is presented together with a discussion of expected problems. | |||

| S02SRU10 | The New Control System for TARN-2 | controls, network, Ethernet, synchrotron | 93 |
|
|||
| The new control system for the cooler-synchrotron, TARN-2, is described. The new control system consists of OPU’s (work stations) and EXU (control computer) linked with the local area network. The text message is used to transfer the control commands and their results. The control program CSA90 at EXU decodes the text message and executes it with the aid of the interface and periodic control subroutines. Both subroutines use common sharable image composed of the status, values, parameters and so on. The CAMAC, GPIB and RS232C are standard interface at EXU. | |||

| S02SRU11 | A New Architecture for Fermilab’s Cryogenic Control System | controls, cryogenics, network, software | 96 |
|
|||
|
In order to achieve design energy in the Tevatron, the magnet system will be operated at lower temperatures. The increased requirements of operating the Tevatron at lower temperatures necessitated a major upgrade to the both the hardware and software components of the cryogenic control system. The new architecture is based on a distributed topology which couples Fermilab designed I/O subsystems to high performance, 80386 execution processors via a variety of networks including: Arcnet, iPSB, and token ring.

| S03SRD04 | Standards and the Design of the Advanced Photon Source Control System | controls, software, network, linac | 116 |
|
|||
|
Funding: Work supported by U.S. Department of Energy, Office of Basic Energy Sciences under Contract No. W-31-109-ENG-38. The Advanced Photon Source (APS), now under construction at Argonne National Laboratory (ANL), is a 7 GeV positron storage ring dedicated to research facilities using synchrotron radiation. This ring, along with its injection accelerators is to be controlled and monitored with a single, flexible, and expandable control system. In the conceptual stage the control system design group faced the challenges that face all control system designers: (1) to force the machine designers to quantify and codify the system requirements, (2) to protect the investment in hardware and software from rapid obsolescence, and (3) to find methods of quickly incorporating new generations of equipment and replace obsolete equipment without disrupting the existing system. To solve these and related problems, the APS control system group made an early resolution to use standards in the design of the system. This paper will cover the present status of the APS control system as well as discuss the design decisions which led us to use industrial standards and collaborations with other laboratories whenever possible to develop a control system. |

| S03SRD05 | The ESRF Control System; Status and Highlights | controls, database, network, device-server | 121 |
|
|||
| The European Synchrotron Radiation Facility (ESRF) will operate a 6 GeV e⁻/e⁺ storage ring of 850 m circumference to deliver to date unprecedented high brilliance X-rays to the European research community. The ESRF is the first member of a new generation of Synchrotron Radiation Sources, in which the brilliance of the beam and the utilization of insertion devices are pushed to their present limits. Commissioning of the facility’s storage ring will start in spring 1992. A full energy injector, consisting of a 200 MeV linear preinjector and a 6GeV fast cycling synchrotron (l0 Hz) of 350 m circumference have been successfully commissioned during the last months. The machine control system for this facility, which is under construction since 1988, is still under development, but its initial on-site operation this year has clearly made easier the commissioning of the preinjector plant. A description of the current system is given and application software for start-up is briefly described. | |||

| We describe the status of the DANTE (DA¿NE New Tools Environment) control system for the new DA{Φ}NE {Φ}-factory under construction at the Frascati National Laboratories. The system is based on a centralized communication architecture for simplicity and reliability. A central processor unit coordinates all communications between the consoles and the lower level distributed processing power, and continuously updates a central memory that contains the whole machine status. We have developed a system of VME Fiber Optic interfaces allowing very fast point to point communication between distant processors. Macintosh II personal computers are used as consoles. The lower levels are all built using the VME standard. | |||

| S03SRD08 | The UNK Control System | controls, software, cryogenics, network | 134 |
|
|||
| The IHEP proton Accelerating and Storage Complex (UNK) includes in its first stage a 400 GeV conventional and a 3000 GeV superconducting ring placed in the same underground tunnel of 20.7 km circumference. The beam will be injected into UNK from the existing 70 GeV accelerator U-70. The experimental programme which is planned to start in 1995, will include 3000 GeV fixed target and 400-3000 GeV colliding beams physics. The size and complexity of the UNK dictate a distributed multiprocessor architecture of the control system. About 4000 of 8/16 bit controllers, directly attached to the UNK equipment will perform low level control and data acquisition tasks. The equipment controllers will be connected via the MIL-1553 field bus to VME based 32-bit front end computers. The TCP/IP network will interconnect front end computers in the UNK equipment buildings with UNIX workstations and servers in the Main Control Room. The report presents the general architecture and current status of the UNK control. | |||

|
|||
| Moscow University race-track microtron (RTM) control system is a star-shape network of LSI-11 compatible microcomputers. Each of them is connected with RTM systems via CAMAC; optical fiber coupling is also used. Control system software is designed on Pascal-1, supplemented with real time modules and Macro. A unified real time technique and re-enterable data acquisition drivers allow to simplify development of control drivers and algorithms. Among the latter three main types are used: DDC methods, those, based on optimization technique and algorithms, applying models of microtron’s systems. Man-machine interface is based on concept of the "world of accelerator". It supports means to design, within hardware possibilities, various computer images of the RTM. | |||

| S03SRD11 | Status Report on Control System Development for PLS | controls, database, network, software | 147 |
|
|||
|
Funding: Work supported by Pohang Iron & Steel Co., Ltd. (POSCO) and Ministry of Science and Technology (MOST), Government of Republic of Korea. Emphasizing reliability and flexibility, hierarchical architecture with distributed computers have been designed into the Pohang Light Source (PLS) computer control system. The PLS control system has four layers of computer systems connected via multiple data communication networks. This paper presents an overview of the PLS control system. The accelerator control system provides means for accessing all machine components so that the whole system could be monitored and controlled remotely. These tasks include setting magnet currents, collecting status data from the vacuum subsystem, taking orbit data with beam position monitors, feedback control of electron beam orbit, regulating the safety interlock monitors, and so forth. To design a control system which can perform these functions satisfactorily, certain basic design requirements must be fulfilled. Among these are reliability, capability, expa.nsibility, cost control, and ease of operation. |

| EUROGAM is an Anglo/French Gamma Ray Detector which will alternate between the Tandem Van der Graaf at Daresbury and the Vivitron at Strasbourg. Because of the need to conform to the standards of Laboratories in two different countries, and the very sensitive nature of electronics for Germanium Gamma Ray telescopes. the newly emerging VXIbus (VMEbus EXtensions for Instrumentation) was chosen as the basis for control and data acquisition. This entailed a major programme of development for both the signal processing front end modules for Germanium and Bismuth Germanate detectors, and also for the hardware and software management of resources from within the VXI environment. The paper will concentrate mainly on the latter areas. | |||

| S05SRN05 | A Control System of the Nobeyama Millimeter Array | controls, software, status, Ethernet | 214 |
|
|||
| We have developed a control system of the Nobeyama Millimeter Array which is a radio interferometer for astronomical observations at millimeter wavelengths. The system consists of three sub-systems (MANAGER, ENGINE, and STATUS CONTROLLER). Observers conduct their observations with MANAGER sub-system, which run on a UNIX workstation. ENGINE is a rigid system on an IBM compatible mainframe. It controls the accurate tracking of astronomical radio objects, and acquires a large amount of observed data from a receiver backend. STATUS CONTROLLER consists of several personal computers which control and monitor the receiver system. These sub-systems are connected with an ethernet. | |||

| S06SA01 | Overview of the Next Generation of Fermilab Collider Software | Windows, controls, collider, data-acquisition | 243 |
|
|||
|
Fermilab is entering an era of operating a more complex collider facility. In addition, new operator workstations are available that have increased capabilities. The task of providing updated software in this new environment precipitated a project called Colliding Beam Software (CBS). It was soon evident that a new approach was needed for developing console software. Hence CBS, although a common acronym, is too narrow a description. A new generation of the application program subroutine library has been created to enhance the existing programming environment with a set of value added tools. Several key Collider applications were written that exploit CBS tools. This paper will discuss the new tools and the underlying change in methodology in application program development for accelerator control at Fermilab.

| S06SA03 | The LEP Alarm System | controls, database, software, operation | 254 |
|
|||
| Unlike alarm systems for previous accelerators, the LEP alarm system caters not only for the operation of the accelerator but also for technical services and provides the direct channel for personnel safety. It was commissioned during 1989 and has seen a continued development up to the present day. The system, comprising over 50 computers including 5 different platforms and 4 different operating systems, is described. The hierarchical structure of the software is outlined from the interface to the equipment groups, through the front end computers to the central server, and finally to the operator consoles. Reasons are given for choosing a conventional, as opposed to a ’knowledge based’ approach. Finally, references are made to a prototype real time expert system for surveying the power converters of LEP, which was conducted during 1990 as part of the alarm development program. | |||

| S06SA05 | A VMEbus General-Purpose Data Acquisition System | data-acquisition, controls, monitoring, real-time | 265 |
|
|||
|
We present a general-purpose, VMEbus based, multiprocessor data acquisition and monitoring system. Events, handled by a master CPU, are kept at the disposal of data storage and monitoring processes which can run on distinct processors. They access either the complete set of data or a fraction of them, minimizing the acquisition dead-time. The system is built with the VxWorka 5.0 real time kernel to which we have added device drivers for data acquisition and monitoring. The acquisition is controlled and the data are displayed on a workstatlon. The user Interface is written in C++ and re-uses the classes of the Interviews and the NIH libraries. The communication between the control workstation and the VMEbus processors is made through SUN RPCs on an Ethernet link. The system will be used for, CAMAC based, data acquisition for nuclear physics experiments as well as for the VXI data taking with the 4π configuration (100 neutron detectors) of the Brussels-Caen-Louvain-Strasbourg DEMON collaboration.

| S07IC01 | Interfacing Industrial Process Control Systems to LEP/LHC | controls, cryogenics, operation, software | 269 |
|
|||
| Modern industrial process control systems have developed to meet the needs of industry to increase the production while decreasing the costs. Although particle accelerators designers have pioneered in control systems during the seventies, it has now become possible to them to profit of industrial solutions in substitution of, or in complement with the more traditional home made ones. Adapting and integrating such industrial systems to the accelerator control area will certainly benefit to the field in terms of finance, human resources and technical facilities offered off-the-shelf by the widely experienced industrial controls community; however this cannot be done without slightly affecting the overall accelerator control architecture. The paper briefly describes the industrial controls arena and takes example on an industrial process control system recently installed at CERN to discuss in detail the related choices and issues. | |||

| S07IC02 | SPS/LEP Beam Transfer Equipment Control Using Industrial Automation Components | controls, software, hardware, electron | 274 |
|
|||
| Several control systems for SPS and LEP beam transfer equipment have to be commissioned in the near future. Tools for fast software development, easy maintenance and modifications, compliance with industrial standards, and independence of specific suppliers are considered to be essential. A large fraction of the systems can be realized using off-the-shelf industrial automation components like industrial I/O systems, programmable logic controllers, or diskless PCs. Specific electronics built up in G-64 can be integrated. Diskless systems running UNIX and X Windows are foreseen as process controllers and local access media. | |||

| S07IC04 | A Front-End System for Industrial Type Controls at the SSC | controls, hardware, software, database | 283 |
|
|||
|
The SSC control system is tasked with coordinating the operation of many different accelerator subsystems, a number of which use industrial type process controls. The design of a high-performance control system front end is presented which serves both as a data concentrator and a distributed process controller. In addition it provides strong support for a centra1ized control system architecture, allows for regional control systems, and simplifies the construction of inter-subsystem controls. An implementation of this design will be discussed which uses STD-Bus for accelerator hardware interfacing, a time domain multiplexing (TDM) communications transport system, and a modified reflective memory interface to the rest of the control system.

| S08NC02 | Multi-Processor Network Implementations in Multibus II and VME | network, software, controls, distributed | 295 |
|
|||
|
ACNET (Fermilab Accelerator Controls Network), a proprietary network protocol, is implemented in a multi-processor configuration for both Multibus II and VME. The implementations are contrasted by the bus protocol and software design goals. The Multibus II implementation provides for multiple processors running a duplicate set of tasks on each processor. For a network connected task, messages are distributed by a network round-routed for each task by user-callable commands. The VME implementation provides for multiple processors running one task across all processors. The process can either be fixed to a particular processor or dynamically allocated to an available processor depending on the scheduling algorithm of the multi-processing operating system.

| S08NC03 | A Distributed Design for Monitoring Logging and Replaying Device Readings at LAMPF | software, controls, network, distributed | 299 |
|
|||
|
Funding: Work supported by the U.S. Department of Energy As control of the Los Alamos Meson Physics linear accelerator and Proton Storage Ring moves to a more distributed system, it has been necessary to redesign the software which monitors, logs, and replays device readings throughout the facility. The new design allows devices to be monitored and their readings logged locally on a network of computers. Control of the monitoring and logging process is available throughout the network from user interfaces which communicate via remote procedure calls with server processes running on each node which monitors and records device readings. Similarly, the logged data can be replayed from anywhere on the network. Two major requirements influencing the final design were the need to reduce the load on the CPU of the control machines, and the need for much faster replay of the logged device readings. |

| S08NC05 | The Transmission of Accelerator Timing Information around CERN | timing, controls, network, operation | 306 |
|
|||
| Prior to the construction of the Large Electron Positron (LEP) collider, machine timing information was transmitted around CERN’s accelerators using a labyrinth of dedicated copper wires. However, at an early stage in the design of the LEP control system, it was decided to use an integrated communication system based on Time Division Multiplex (TDM) techniques. Therefore it was considered appropriate to use this facility to transmit timing information over long distances. This note describes the overall system, with emphasis placed on the connectivity requirements for the CCITTG.703 series of recommendations. In addition the methods used for error detection and correction, and also for redundancy, are described. The cost implications of using such a TDM based system are also analyzed. Finally the performance and reliability obtained by using this approach are discussed. | |||

| S08NC07 | The ELETTRA Field Highway System | controls, software, network, hardware | 313 |
|
|||
| ELETTRA is a third generation Synchrotron Light Source under construction in Trieste (Italy); it consists of a full energy linac injector and a storage ring with beam energies between 1.5 and 2 GeV. The ELETTRA control system has a distributed architecture, hierarchically divided into three layers of computers; two network levels provide communication between the adjacent computer layers. The field highway adopted for the connection of the middle-layer local process computers with the bottom-layer equipment interface units is the MIL-1553B multidrop highway. This paper describes the hardware configuration and the main communication services developed on the MIL-15538 field highway for accelerator control. As an additional feature, typical LAN utilities have been added on top of the basic MIL-15538 communication software allowing remote login and file transfer; these tools are currently used for software development in our laboratory. | |||

|
|||
| The control system for KEK 12 GeV Proton Synchrotron has been replaced with a distributed VME-bus based microcomputer system and a MAP local area network. In order to simplify programming for network application tasks, a set of a preprocessor for a PASCAL compiler and a network communication server has been developed. Application programs for accelerator control system have blocks with similar codes; sending, waiting for, receiving, analyzing messages, etc. The preprocessor called "OBJP" incorporates such common codes into the source code written by an application programmer. In case of a simple program, the size of the source code is reduced by one tenth of a full coding. | |||

| S10TS01 | Realtime Aspects of Pulse-to-Pulse Modulation | controls, timing, real-time, ECR | 345 |
|
|||
| The pulse-to-pulse modulation of the SIS-ESR control system is described. Fast response to operator interaction and to changes in process conditions is emphasized as well as the essential part played by the timing system in pulse-to-pulse modulation. The benefits of pulse-to-pulse modulation in acceleration operating have been described as early as ’77 for the CERN’s PS complex. It is an effective way to increase the overall output of valuable beamtime of one or more accelerators. With beamsharing, rarely all users of the beam will be unable to accept the beam at the same time. If the PPM-handling quickly responds to changing conditions, there will be virtually no dead-time in the machine operating due to inevitable dead-times of experiments, e.g. during new experimental setups. In a multi-accelerator facility, PPM is almost imperative. Asynchronously running machines, every one of them operating as an injector for the next one, normally have time left between subsequent injections that can be used for experiments. | |||

| S11LLC01 | Replacing PS Controls Front End Minicomputers by VME Based 32-bit Processors | controls, network, real-time, software | 375 |
|
|||
| The PS controls have started the first phase of system rejuvenation, targeted towards the LEP Preinjector Controls. The main impact of this phase is in the architectural change, as both the front-end minicomputers and the CAMAC embedded microprocessors are replaced by microprocessor based VME crates called Device Stub Controllers (DSC). This paper discusses the different steps planned for this first phase, i.e: - implementing the basic set of CERN Accelerator common facilities for DSCs (error handling, system surveillance, remote boot and network access); - porting the equipment access software layer; ¿ applying the Real-time tasks to the LynxOS operating system and J/O architecture, conforming to the real-time constraints for control and acquisition; - defining the number and contents of the different DSC needed, according to geographical and cpu-load constraints; - providing the general services outside the DSC crates (file servers, data-base services); - emulating the current Console programs onto the new workstations. | |||

| S11LLC06 | Beam Position Monitor Multiplexer Controller Upgrade at the LAMPF Proton Storage Ring | controls, diagnostics, software, timing | 393 |
|
|||
|
Funding: Work supported by the U.S. Department of Energy The beam position monitor (8PM) is one of the primary diagnostic tools used for the tuning of the proton storage ring (PSR) at the Clinton P. Anderson Meson Physics Facility (LAMPF). A replacement for the existing, monolithic, wire-wrapped microprocessor-based BPM multiplexer controller has been built. The controller has been redesigned as a modular system retaining the same functionality of the original system built in 1981. Individual printed circuit cards are used for each controller function to insure greater maintainability and ease of keeping a spare parts inventory. Programmable logic device technology has substantially reduced the component count of the new controller. Diagnostic software was written to support the development of the upgraded controller. The new software actually uncovered some flaws in the original CAMAC interface. |

|

Funding: Work supported by Department of Energy contract DE-AC03-76SF00515. A Machine Protection System implemented on the SLC automatically controls the beam repetition rates in the accelerator so that radiation or temperature faults slow the repetition rate to bring the fault within tolerance without shutting down the machine. This process allows the accelerator to aid in the fault diagnostic process, and the protection system automatically restores the beams back to normal rates when the fault is diagnosed and corrected. The user interface includes facilities to monitor the performance of the system, and track rate limits, faults, and recoveries. There is an edit facility to define the devices to be included in the protection system, along with their set points, limits, and trip points. This set point and limit data is downloaded into the CAMAC modules, and the configuration data is compiled into a logical decision tree for the 68030 processor. |

| Within the framework of the rejuvenation project of the CERN control systems, commercial workstations have to replace existing home-designed operator consoles. RISC-based workstations with UNIX®, X-window¿ and OSF/Motif¿ have been introduced for the control of the PS complex. The first versions of general functionalities like synoptic display, program selection and control panels have been implemented and the first large scale application has been realized. This paper describes the different components of the workstation environment for the implementation of the applications. The focus is on the set of tools which have been used, developed or integrated, and on how we plan to make them evolve. | |||

| A large community is now using Workstations as Accelerators Computer Controls Interface, through the concepts of windows - menus - synoptics - icons. Some standards were established for the CERN-PS control systems rejuvenation. The Booster-to-PS transfer and injection process is now entirely operated with these tools. This application constitutes a global environment providing the users with the controls, analysis, visualization of a part of an accelerator. Individual commands, measurements, and specialized programs including complex treatments are available in a homogeneous frame. Some months of experience in current operation have shown that this model can be extended to the whole project. | |||

| ELETTRA is a third generation Synchrotron Light Source under construction in Trieste (Italy), with beam energies between 1.5 and 2 GeV. Two networks connect three layers of computers in a fully distributed architecture. An ergonomic and unified approach in the realization of the human interface for the ELETTRA storage ring has led to the adoption of artificial reality criteria for the definition of the system synoptic representation and user interaction. Users can navigate inside a graphic database of the whole system and interactively edit specific virtual control panels to operate on the controlled equipment. UNIX workstations with extended graphic capabilities as operator consoles are used in the implementation of the PSI (Programmable Synoptic Interface), that was developed on top of X11 and the Programmer’s Hierarchical Interactive Graphics System (PHIGS) standards. | |||

| S13MMI06 | A Virtual Control Panel Configuration Tool for the X-Window System | controls, software, EPICS, network | 468 |
|
|||
|
Funding: Work supported and funded under the Department of Defense, US Army Strategic Defense Command, under the auspices of the Department of Energy. Computer Graphics Workstations are becoming increasingly popular for use as virtual process control and read back panels. The workstation’s CRT, keyboard, and pointing device are used in concert to produce a display that is in essence a control panel, even if actual switches and gauges are not present. The code behind these displays is most often specific to one display and not reusable for any other display. Recently, programs have been written allowing many of these virtual control panel displays to be configured without writing additional code. This approach allows the initial programming effort to be reapplied to many different display instances with minimal effort. These programs often incorporate many of the features of a graphics editor, allowing a pictorial model of the process under control to be incorporated into the control panel. We have just finished writing a second generation software system of this type for use with the X-Window system and the Experimental Physics and Industrial Control System (EPICS). This paper describes the primary features of our software, the framework of our design, and our observations after initial installation. |

| S13MMI09 | Porting Linac Applieation Programs to a Windowing Environment | controls, linac, optics, software | 479 |
|
|||
| We report our experience in porting Linac application programs written for CAMAC controlled hardware consoles to an X·Windows/Motif based workstation environment. Application programs acquire their parameter values from a front end computer (FEC), controlling the acceleration process, via a local area network. The timing for data acquisition and control is determined by the particle source timing. Two server programs on the FEC for repetitive acquisition and command-response mode will be described. The application programs on the workstations access a common parameter access server who establishes the necessary connection to the parameters on the FEC. It displays the parameter’s current values and allows control through Motif interactive synoptics editor and its corresponding driver program allow easy generation of synoptics displays and interaction through command panels. | |||

| S13MMI10 | A New Workstation Based Man/Machine Interface System for the JT-60 Upgrade | operation, controls, man-machine-interface, network | 483 |
|
|||
| Development of a new man/machine interface system was stimulated by the requirements of making the JT-60 operator interface more "friendly" on the basis of the past five-year operational experience. Eleven Sun/3 workstations and their supervisory mini-computer HIDIC V90/45 are connected through the standard network; Ethernet. The network is also connected to the existing "ZENKEI" mini-computer system through the shared memory on the HIDIC V90/45 minicomputer. Improved software, such as automatic setting of the discharge conditions, consistency check among the related parameters and easy operation for discharge result data display, offered the "user-friendly" environments. This new man/machine interface system leads to the efficient operation of the JT-60. | |||

| S13MMI13 | Correlation Plot Facility in the SLC Control System | controls, klystron, software, feedback | 493 |
|
|||
|
Funding: Work supported by Department of Energy contract DE-AC03-76SF00515. The Correlation Plot facility is a powerful interactive tool for data acquisition and analysis throughout the SLC. This generalized interface allows the user to perform a range of operations or machine physics experiments without the need for any specialized analysis software. The user may step one or more independent parameters, such as magnet or feedback setpoints, while measuring or calculating up to 160 other parameters. Measured variables include all analog signals available to the control system, as well as calculated parameters such as beam size, luminosity, or emittance. Various fitting algorithms and display options are provided. A software-callable interface has been provided so that a host of applications can call this package for analysis and display. Such applications regularly phase klystrons, measure emittance and dispersion, minimize beam size, and maintain beam collisions at the interact ion point. |

| S13MMI14 | Iconic Representation of Particle Beams Using Personal Computers | controls, emittance, Windows, ion-effects | 496 |
|
|||
| The idea of representing the character of a charged particle beam by means of its emittance ellipses, is essentially a mathematical one. For quick understanding of the beam character in a more user-friendly way, unit beam cells with particles having a uniform nature, have been pictured by suitably shaped 3-D solids. The X and Y direction momenta at particular cell areas of the particle beam combine together to give a proportionate orientation to the solid in the pseudo 3-D world of the graphic screen, creating a physical picture of the particle beam. This is expected to facilitate the comprehension of total characteristics of a beam in cases of online control of transport lines and their designs, when interfaced with various ray-tracing programs. The implementation is done in an IBM-PC environment. | |||

| S14OOP01 | Object-Oriented Programming Techniques for the AGS Booster | controls, booster, MMI, software | 500 |
|
|||
|
Funding: Work performed under the auspices of the U.S. Department of Energy. The applications software developed for the control system of the AGS Booster Project was written in the object-oriented language, C++. At the start of the Booster Project, the programming staff of the AGS Controls Section comprised some dozen programmer/analysts, all highly fluent in C but novices in C++. During the course of this project, nearly the entire staff converted to using C++ for a large fraction of their assignments. Over 100 C++ software modules are now available both for Booster and general AGS use, of which a large fraction are broadly applicable tools. The transition from C to C++ from a managerial perspective is discussed and an overview is provided of the ways in which object classes have been applied in Booster software development. |

| S14OOP02 | A Simplified Approach to Control System Specification and Design Using Domain Modelling and Mapping | controls, kaon, factory, software | 505 |
|
|||
| Recent developments in the field of accelerator-domain and computer-domain modelling have led to a better understanding of the "art" of control system specification and design. It now appears possible to "compile" a control system specification to produce the architectural design. The information required by the "compiler" is discussed and one hardware optimization algorithm presented. The desired characteristics of !he hardware and software components of a distributed control system architecture are discussed and the shortcomings of some commercial products. | |||

| S14OOP03 | The Direct Manipulation Shell: Creating Extensible Display Page Editors | MMI, software, software-component, controls | 511 |
|
|||
|
Accelerator controls systems provide parameter display pages which allow the operator to monitor and manipulate selected control points in the system. Display pages are generally implemented as either hand-crafted, purpose-built programs; or by using a specialized display page layout tool. These two methods of display page development exhibit the classic trade-off between functionality vs. ease of implementation. In the Direct Manipulation Shell we approach the process of developing a display page in a manifestly object-oriented manner. This is done by providing a general framework for interactively instantiating and manipulating display objects.

| S14OOP06 | The State Manager: A Tool to Control Large Data-Acquisition Systems | controls, data-acquisition, distributed, MMI | 524 |
|
|||
| The State Manager system (SM) is a set of tools, developed at CERN, for the control of large data-acquisition systems. A dedicated object-based language is used to describe the various components of the data-acquisition system. Each component is declared in terms of finite state machines and sequences of parametrized actions to be performed for operations such as the start and end of a run. The description, written by the user, is translated into Ada to produce a run-control program capable of controlling processes in a distributed environment A Motif-based graphical interface to the control program displays the current state of all the components and can be used to control the overall dataa-cquisition system. The SM has been used by several experiments both at CERN and other organizations. We present here the architecture of the SM, some design choices, and the experience acquired from its use. | |||

| S15CSE02 | Automation from Pictures: Producting Real Time Code from a State Transition Diagram | controls, database, real-time, software | 535 |
|
|||
|
Funding: Work supported and funded under the Department of Defense, US Army Strategic Defense Command, under the auspices of the Department of Energy. The state transition diagram (STD) model has been helpful in the design of real time software, especially with the emergence of graphical computer aided software engineering (CASE) tools. Nevertheless, the translation of the STD to real time code has in the past been primarily a manual task. At Los Alamos we have automated this process. The designer constructs the STD using a CASE tool (Cadre Teamwork) using a special notation for events and actions. A translator converts the STD into an intermediate state notation language (SNL), and this SNL is compiled directly into C code (a state program). Execution of the state program is driven by external events, allowing multiple state programs to effectively share the resources of the host processor. Since the design and the code are tightly integrated through the CASE tool, the design and code never diverge, and we avoid design obsolescence. Furthermore, the CASE tool automates the production of formal technical documents from the graphic description encapsulated by the CASE tool. |

| S16MS02 | Framework for Control System Development | controls, distributed, network, software | 542 |
|
|||
|
Funding: This work was supported by the US DOE under Contract No. DE-AC03-76SF00098 Control systems being developed for the present generation of accelerators will need to adapt to changing machine and operating state conditions. Such systems must also be capable of evolving over the life of the accelerator operation. Several of the new generation of control systems hardware being developed today have the capability of fast, sophisticated control at all levels in the control hierarchy. These systems are typically hierarchical and highly distributed with extremely high I/O throughput. We have initiated the design of a framework for control system development which can accommodate the new architectures. This paper will present requirements, design decisions, and specifications that we have devised for this framework. |

| S16MS03 | The LEP Model Interface for MAD | controls, closed-orbit, operation, network | 546 |
|
|||
| During machine studies and trouble-shooting in the LEP machine various optical parameters must be computed, which can be found quickly using the MAD program. However, the LEP operators are not all well acquainted with MAD. In order to ease their task, a simple interface called the LEP model has been written to run on the Apollo workstations of the LEP control system. It prepares jobs for MAD, sends them to a DN 10000 node for execution, and optionally plots the results. The desired machine positions and optical parameters vary between LEP runs. The LEP model contains a powerful selection algorithm which permits easy reference to any combination of positions and optical parameters in the machine. Elements can be chosen by name, by sequence number, or by element class. The choice of optical functions includes closed orbit, Twiss parameters, betatron phases, chromatic functions, element excitations, and many more. Recently matching features have been added. Communication with the control system and with MAD uses self-describing tables, i.e. tables whose columns are labelled with their name and a format code. Experience with this LEP model interface is reported. | |||
