  The PSI 590-MeV Cyclotron is already more than 30 years in operation. However, it still holds the world record in continuous beam power. There is an active experiment program being pursued, and new experiments are planned and being built. In addition, the beam intensity is being upgraded by 50%. The control system has been through several incremental upgrades. However, the new requirements and other developments at PSI (other accelerator facilities) force again an upgrade. This time the whole architecture of the system is to be changed. The controls hardware architecture will be changed and the underlying software will move to EPICS. All this has to happen without compromising the operation schedule. In the upgrade program we are planning to benefit from several new developments, both in-house and together with the community. The central technologies to be used will be presented. The issue of how to tackle the somewhat contradictory goals of upgrading on the fly will be discussed.

  The Tore Supra tokamak is the largest superconducting magnetic fusion facility. Its real time measurements and control system is designed to deal with continuous acquisition during the plasma discharge, fast acquisition (sampling frequency up to 4 GHz) and Real Time (RT) data processing. The simultaneous control of an increasing number of plasma parameters aiming at tokamak operations in a fully steady state regime makes fast acquisitions and RT data processing more and more de-manding. The Tore Supra Data Acquisition System (DAS) is based mainly on VME bus acquisition units using Lynx OS 3.1 as operating system. Some units are not able any more to handle in parallel the data flow rate (about 100ko/s increasing up to 6Mo/s during fast acquisition phase) and the RT processing. Furthermore, the time delay between two fast acquisition phases must be reduced to be able to catch fast plasma events. To cope with these needs, the data processing capability has been enhanced while preserving the existing acquisition system. A new DAS layer containing Linux-PC has been implemented. The link between the Lynx-OS layer and the Linux layer is ensured by a 100-Mbps Ethernet link.  
TOPB03 The Evolution of the ELETTRA Control System 265

  The evolution of the ELETTRA control system is presented by focusing on the major technical upgrades. The ElETTRA control system has been in operation since 1993. The orginal control system architecture was based on a three layer design. A field bus connected the low level computers used to interface the accelerator devices whilst a ten megabit shared Ethernet network linked the middle layer computers to the servers and operator workstations. A first control system upgrade started in 1998 in order to dismiss the field bus and to provide more computing power. A couple of years later a major rework of the network infrastructure was carried out with the introduction of a switched Ethernet architecture. Starting from 2003, in view of the construction of a new booster injector for the storage ring and of the FERMI@elettra free electron laser, new control system hardware and software platforms have been selected. Driven by the additional necessity of cutting development and maintenance costs, the Tango control system has been adopted. The tools developed in order to effectively manage the integration and coexistence of the legacy and new control system are described.

  The KEKB asymmetric electron-positron collider complex consists of 8-GeV Linac, high-energy and low-energy rings. Some of the resources were inherited from the previous TRISTAN project, and also they are shared with Photon Factory and PF-AR light sources. In order to realize the long lifespan of the system de-facto and international standard technologies were employed since the early stage, which have been efficiently operated. Several gateway methods were implemented to integrate heterogeneous sub-systems, which are gradually converted into EPICS. Scripting languages are employed for higher-level applications. The ever-evolving control system has enabled flexible and reliable beam operations at KEKB throughout the long period.

  The SSW system developed by Fermilab, USA, has been the main device heavily used since 2004 at CERN for certain required measurements of all the LHC Quadrupole assemblies as well as certain measurements for the LHC Dipoles. All these structures also include various small and large corrector magnets. A novel system is proposed, based on three years of operational experience in testing the LHC Magnets on a round-the-clock basis. A single stretched wire system is based on the wire cutting the magnetic flux, producing the electrical potential signal. Presently this signal is integrated with a VME-based data acquisition system and is used to analyse the magnetic field. The acquisition and control is currently done via a SUN workstation communicating between different devices with different buses and using different protocols. The new system would use a PXI based data acquisition system with an embedded controller; the different devices are replaced by PXI-based data acquisition and control cards using a single bus protocol and on one chassis. The use of windows based application software would enhance the user friendliness, with overall costs of the order of 10 KCHF.

  Baseline design of the Taiwan photon Source (TPS) control system of NSRRC is proposed. The control system design is based on EPICS toolkits due to it has large user base in synchrotron light source around the world. Guidelines for hardware platform and operating system choice will be addressed. The standard hardware interface driver is developing and testing now. The asynchronous driver of EPICS will be applied to be the most of standard hardware interface. The expected control system for TPS will provide versatile environments for machine commissioning, operation, and research. The open architecture led machine upgrade or modify without toil. Fewer efforts for machine maintenance are essential. Performance and reliability of the control system will be guarantee form the design phase. Design consideration will be summary in this report.

  OASIS, the Open Analogue Signal Information System, was fully deployed in 2006 and now allows observation of more than 1900 analogue signals in the CERN accelerator complex. Our first operational experience in 2005 indicated that, for performance reasons, a change in the technology used to access the database was needed. Further experience throughout 2006 showed that an even bigger move was required in order to keep the system easy to maintain and improve. Initially based on the J2EE Enterprise Java Beans (EJB) and Java Messaging Service (JMS), the OASIS server was tightly coupled to OC4J, the Oracle’s EJB container, and SonicMQ, a JMS broker. The upgrade to the latest version of these products being unnecessary complex and the architectural constrains being major drawbacks of the EJBs, it was decided to move completely away from those. The paper presents the new server architecture based on open-source products – Spring, ActiveMQ & Hibernate. It also presents the improvements done to the user request processing in order to reduce drastically the response time. Finally, the concept of Virtual Signal is introduced along with the new scalability constraint it brings into the system.  
WPPA05 The LANSCE Timing System Upgrade 325
 
  • E. Bjorklund
    LANL, Los Alamos, New Mexico
 
  As part of a planned upgrade project for the Los Alamos Neutron Science Center (LANSCE) accelerator, we are considering replacing our current timing system, which distributes each timing signal on its own dedicated wire, with a more modern event-driven system. This paradigm shift in how timing signals are generated and distributed presents several challenges that must be overcome if we are to preserve our current operational capabilities. This paper will discuss some of the problems and possible solutions involved with migrating to an event system. It will also discuss some recent enhancements to theμResearch, Finland (MRF) event system that will help us accomplish our goal.  
WPPA06 An Embedded EPICS Controller Based on Ethernet/Serial Box 328
 
  • L. R. Shen, G. Y. Jiang

  The control system of SSRF takes the Ethernet as backbone. All kinds of serial devices such as vacuum pumps are connected to Linux IOCs via a kind of Ethernet/serial box made by Moxa company. In the preresearch stage of SSRF, the old model of this Ethernet/serial box was only a simple Ethernet/serial protocol converter which was functioned by firmware. Aim to this, we have developed several kinds of EPICS device drivers based on NetDev for our serial devices. Recently, Moxa company has upgraded the converter by replacing old arm9 CPU with a more powerful Intel Xscale CPU. It supports Monta Vista Linux as its embedded OS, also cross-compiler is provided to make further development available. Since we have decided to use the new model of converter in our facility finally, we manage to port EPICS IOC core on Monta Vista Linux and implement the same function on the new converter as old one's to avoid modifying existent EPICS device driver. By these, the dedicated Linux IOC can be omitted and the whole system can be more efficient and expandable. Details of the necessary integration work and initial operation experience will be discussed in this paper.

  The MAMI electron accelerator cascade of three Racetrack Microtrons (RTMs) has been upgraded by a 4th stage, a Harmonic Double Sided Microtron (HDSM), raising the output energy from 0.855GeV to 1.5GeV. The control system for this worldwide unique machine has been built by extending and updating the well proven system of the three RTMs described at the ICALEPCS'99*. To accomplish this, software to control a couple of new devices had to be implemented, the operator interface was rebuilt and new PC-based VME-front-end computers were developed. To supply the large number of correction dipole steerers on the 43 recirculation paths, a new type of multi-channel power supplies was developed in-house. An enhanced system for digitising the signals of the rf-position monitors on the linac axes has been set up to improve the automatic beam position optimisation in the RTMs and to enable it in the HDSM.

WPPA09 Development of Embedded System for Running EPICS IOC by Using Linux and a Single Board Computer 334

  We constructed a control system based on the Experimental Physics and Industrial Control System (EPICS) for the RIKEN RI-beam Factory (RIBF) project. Nowadays, the PC-based EPICS Input Output Controller (IOC) is used in many laboratories because it is available for use on the Linux x86 platform since EPICS was upgraded to version R3.14. If the number of PC-based IOC increases, the probability of trouble rises dramatically. Consequently, it is difficult to supply reliable hardware. Furthermore, if a lot of desktop PCs are used for running IOC only, it is very hard to maintain it. The purpose of this development is to give the high durability system for running IOC computer and the ability for all accelerator operators to maintain it easily. We expect we can solve the problems described above using a diskless and fanless embedded single board computer (SBC) for running IOC and managing IOC in the fileserver collectively. For this reason, we developed a compact and simple Linux distribution specialized for running IOC and introduced IOC, which is installed in the SBC, into RIBF control system. In our contribution, we report this system and present the status in detail.

  The Very Large Telescope (VLT) will remain in operation most probably for at least two more decades. Being the software technology currently used at the VLT and more than one decade old, the maintanability of such a complex system might become a critical issue. The ALMA Common Software (ACS) is based on newer technology. Following this consideration, one of the obvious options to improve the maintainability of the VLT Software would be to port it, or parts of it, to ACS. This would allow optimizing maintenance resources for both VLT and ALMA Software, eventually making available resources for new ESO projects, such as E-ELT. Because of operational constraints, this can only be achieved gradually, possibly starting with new VLT sub-systems. In the year 2004 a pilot project has been started to study the effort needed to replace standard components of the VLT Instrumentation Software with ACS based ones. Starting from a simple instrument created from the VLT Template Instrument and entirely based on the VLTSW, we have replaced the core of the Observation Software (OS) with an ACS based equivalent. The purpose of this paper is to summarize the work done and draw some conclusions.

  The STAR (Solenoidal Tracker At RHIC) experiment located at Brookhaven National Laboratory has been studying relativistic heavy ion collisions since it began operation in the summer of 2000. An EPICS-based hardware controls system monitors the detector's 40000 operating parameters. The system I/O control uses VME processors and PCs to communicate with sub-system based sensors over a variety of field busses. The system also includes interfaces to the accelerator and magnet control systems, an archiver with CGI web based interface and C++ based communication between STAR online system, run control and hardware controls and their associated databases. An upgrade project is underway. This involves the migration of 60% of the I/O control from the aging VME processors to PC's. The host system has been transferred from Sun OS to Scientific Linux and some of the VME boards were replaced with "softIOC" applications. The experience gained with the current setup will be discussed, and upgrade plans and progress will be outlined.

  There are 70 vertical and 70 horizontal correctors for Pohang Light Source. Until 2003, power supplies for these correctors were based on 1980’s technology, so the global orbit feedback system was not possible with poor 12-bit resolution. In 2003, a task force team was assembled to develop new power supplies with BESSY type ADC cards. By Summer 2004, two vertical correctors in each lattice were connected with new power supplies, and the global orbit feedback was available within the accuracy of 5 microns. However, this replacement was not enough to satisfy the beam stability requirement of 2 microns for PLS. We have launched another power supply design based on all digital technology. This attempt was completed within a year, and 80 units were assembled in house. Currently, the global orbit feedback system is running successfully with new digital power supplies and the compensation of chamber motion due to the thermal load by using digital displacement transducers attached on each BPMs.

  The non-destructive beam probe is based on the scanning of a thin electron beam within the energy range 20-100 kV in the electromagnetic field of an intensive relativistic bunch. A CCD-camera is used to view the beam "image." Initially the facility was controlled by a standalone application. This was dictated mainly by specifics of a CCD-camera and digital oscilloscopes, which are required for tuning. Now, when CCD-camera and digital oscilloscopes are fully supported by a CX networked control system (based on the 3-layer model), the standalone application was replaced by a CX-based set of programs. This enables remote operation, with several applications running in parallel. Additionally, this architecture allows use of scripting facilities to automate various routine tasks, which previously had to be done by hand.

  We upgraded the BPM data acquisition system of the PLS 2.5-Gev storage ring with the use of RFM (Reflective Memory). Our present BPM data acquisition system is based on EPICS VME IOC. It uses an analog-to-digital converter with 16-bit resolution and a 100-KHz conversion rate to digitize BPM raw electric signals. To get better position data from the digitized raw BPM data, we developed BPM data-averaging software utilizing RFM. With this averaging software, we could average 4000 samples of raw BPM data with the refresh rate of 2 seconds and get much better position data compared with the previous one. We installed data-averaging software and reflective memory modules into 12 local BPM IOCs for the routine operation. We are also planning to develop a fast global feedback system using RFM to improve beam quality in the near future.

  Since beginning 2006 the LNL ECR ion source on a 350-kV high-voltage platform must to supply reliable and stable beams for the operation of a linear accelerators complex: the superconducting PIAVE injector and the superconducting linear accelerator ALPI. At the end of 2006 a new spectra acquisition system was put into operation for the ECRIS setup and beam periodic checks. The previously used spectra acquisition system was running only on a local scope on the high-voltage platform while the new system was required to work both on the local and on the remote control computer in the console room. To achieve this goal a set of new devices had to be integrated in the standard remote control system. New software modules had also to be developed and integrated in the existent and working control system. An important goal of this upgrade was to assembly a tool that may be easily installed, used and maintained on different computer platforms (Linux and Windows PCs) and that may cope with future changes in the hardware devices to be used for spectra acquisition. Here a survey of this new facility is given.

  We introduced the virtualization technology to more than 50 workstations in SPring-8 beamlines to reduce into 8 servers. The virtualization technology is a hot topic for server computing. It enables to consolidate a lot of computers to a few host computers. We presented the experiment of introduction of the virtualization technology at previous ICALEPCS conference. In SPring-8, about 50 beamlines are in operation. Each beamline had one workstation for an operator console to avoid interference from other beamline operation. The virtualization technology reduces hardware and maintenance costs while ensuring independency of a computing environment in each beamline. This paper describes the process and the result of the migration to the virtualization environment. In addition, we show changes of a topological network configuration for the virtualization environment.

  Since the change-over to EPICS in 2001, further developments in soft- and hardware and continuous improvements concerning the control system infrastructure as well as the accelerator modelling have been performed. A set of new applications like a bunch filling pattern control and a revised tune measurement software have been established. Furthermore, a new web-server including a content management system has been installed. The complete EPICS data logging and the electronic shift book entries are now managed by a MySQL database. Necessary preparations for automatic machine operation (unmanned control room) are in progress. This article summarizes the activities during the last years and plans for the future.

  The Free Electron Laser in Hamburg (FLASH), with its complex accelerator diagnostics and user experiments, requires a lot of different cameras for both the operation and the experiments. A common interface for simple USB cameras, for fire wire cameras, and for high resolution cameras with, e.g. multiple "region of interest" was developed. This system integrates the various camera types in a transparent way into the FLASH control system DOOCS. In addition, the cameras are connected to a fast data acquisition system (DAQ). The DAQ provides the synchronization with other diagnostics data, online processing of the images, and a long time archiving.

  The Joint European Tokamak (JET) is a large machine for experiments on fusion plasmas. Many of the experiments use real-time measurements and controls to establish and/or maintain specific plasma conditions. Each Instrument (Diagnostic or Heating/Fueling/Magnet) is connected to a network. The number of systems has now grown to over thirty, and new systems are being planned for the future. Since some of the systems are used to control critical parameters of the JET plasma, we are improving the availability, reliability, and maintainability of the facility. We must ensure that systems check their message structures against a central Data Dictionary at build-time and run-time and secondly that the systems check their input data streams are alive before, during, and after a JET pulse. Thirdly, a test data generator facility is being added so that systems can be validated in situ. Finally, we are developing high-level control configuration tools. From all of these, we identify some general principles that are applicable to the next-generation machines.  
WPPA24 EPICS CA Enhancements for LANSCE Timed and Flavored Data 365

  Currently the subscription update event queue in the EPICS server is capable of carrying event payloads consisting always of the channel’s value, time stamp, and alarm state. The complexity of the LANSCE macro pulse beam gates requires unique capabilities within the LANSCE control system - which is currently only partly based on an EPICS core. Upgrade designs specify a 100% EPICS based system, but this has evolved new requirements for enhanced capabilities within EPICS. Specifically, EPICS Channel Access (CA) clients need to dynamically specify the LANSCE macro pulse beam gate combinatorial (LANSCE Flavored Data), and the timing offsets (LANSCE Timed Data), to be viewed when they subscribe. EPICS upgrades in progress fulfilling these requirements, including generic software interfaces accommodating site specific event queue payloads and client specified subscription update filters, will be described.

Prototype of current transformer(CT) and beam position monitor(BPPM) were made and tested successfully in tools of the beam diagnostic systems. We are preparing to monitor remotely signals from the diagnostic system. Remote monitoring system is based on VME system with EPICS environments. For fast digitizing the analog signals VME ADC Input Output Board (VTR812/10) are used to meet the various needs of beam diagnosis device. EPICS channel access and drivers have been programmed in VME CPU to operate the Input output controller(IOC) and interface operators. Operator console and data storage have been implemented with EDM and channel archiver as well.

  The upgraded Beamline 2C Solid Target Facility was recently commissioned at TRIUMF. The original facility had run successfully producing radioisotopes since 1989. To improve reliability and maintainability, and to allow increased incident beam currents, an upgrade project was established. The basic functionality of the facility was retained but changes were made in a number of areas such as aspects of the control system and physical components in the beamline. The process and results of the commissioning, the reasons for upgrading, and the lessons learned are discussed.

  Tango is a control system based on the device server concept. It is currently being actively developed by 4 (soon 5) institutes, 3 of which are new institutes. This alone is a good reason that Tango integrates the latest developments in control systems evolution. One of the evolutions in computing is ubiquitous computing. Ubiquitous computing in control systems means integrating computers and intelligence into every aspect of the control system. This paper will present how Tango has been integrated into a wide variety of embedded systems from FPGAs, Gumstix, Liberas, and even PS3s (if my boss would buy me one).

  The market for industrial vision components is evolving towards GigE Vision (Gigabit Ethernet vision standard). In recent years, the usage of TV systems/optical readout at accelerator facilities has been increasing. The Video System at PITZ, originated in the year 2001, has overcome a huge evolution over the last years. Being real-time capable, lossless capable, versatile, well-documented, interoperable, and designed with the user's perspective in mind, use cases at Petra 3 and EMBL at DESY Hamburg have been implemented to great success. The wide use range spans from robotics to live monitoring up to precise measurements. The submission will show the hardware and software structure, components used, current status as well as a perspective for future work.

  An accelerator console system, based on a commercial thin client, has been developed for J-PARC accelerator operation and software development. Using thin client terminals, we expect a higher reliability and longer life-cycle due to more robust hardware (i.e., diskless and fanless configuration) than standard PCs. All of the console terminals share a common development/operation environment. We introduced LDAP (Lightweight Directory Access Protocol) for user authentication and NFS (Network File System) to provide users with standard tools and environment (EPICS tools, Java SDK, and so on) with standard directory structures. We have used the console system for beam commissioning and software development in the J-PARC. This paper describes early experiences with them.

  The current GSI control system uses a very monolithic approach that made it difficult to extend the system to other than the original platforms (VME front ends and OpenVMS on the application level). For the present renovation project of the communication layers, flexibility was a major design criterion. Front-end and application levels are connected via CORBA middleware, giving free choice for using various system architectures and programming languages on both levels. While most of the current front-end software will be ported to the existing VME front-end environment, now running Linux, the new system can integrate devices running on various architectures and operating systems into the new GSI control system. To model equipment functionality as independently as possible, generating adapter code from a well-defined XML description of device models is now under development. This will make the task of porting the existing 65 device models (including around 3000 properties) to the new modular approach easier. We will present the current state of this project and future plans.

  The Spallation Neutron Source Front End (FE) is comprised of a 35-70 mA volume H-source, a multi-element electrostatic LEBT including chopping and steering, a 402.5MHz RFQ with low output emittance, and a 2.5MeV MEBT that also includes chopping. The original control system was designed and built by LBNL during 2000-2002 and commissioned at SNS in 2003. The FE control system design occurred early in the project and preceded finalization of SNS control system standards. The system was implemented based on Allen-Bradley VMEBus Remote I/O Scanners and PLC5s with Flex I/O interfaced via Remote I/O communication. The FE control system is now being upgraded to comply with the SNS standard PLC implementation and to improve reliability and maintainability. Details on the upgrade will be presented in this paper.

  The PLS SMS mobile system is based on Linux PC platform. The SMS mobile system is equipped with a wireless SMS(Simple Message Service) interface giving an opportunity to use fault alarm interlock system. It was developed as a network-based distributed real-time control system composed of several subsystems (EPICS IOC and PLC system). The mobile system sends simple message of fault trip signal to users’ mobile devices with fault tag address and immediately sends warning or alert messages to mobile devices, or remote users are real-time monitoring the device fault states by mobile devices. Control systems can be set remotely by mobile devices in emergency situation. In order to provide suitable actions against system fault, SMS Mobile System will enable system administrator to promptly access, monitor and control the system whenever users want and wherever users are, by utilizing wireless Internet and mobile devices. This paper presents the Mobile SMS system for PLS Control System.

  Tango is a control system based on the device server concept. It is currently being actively developed by 4 (soon 5) institutes, 3 of which are new institutes. In October 2006 the Tango community met in the French Alps to discuss the future evolution of Tango. This paper summarizes the fruits of this meeting. It presents the different areas Tango will concentrate on for the next 5 years. Some of the main topics concern services, beamline control, embedded systems on FPGA, 64-bit support, scalability for large systems, faster boot performance, enhanced Python and Java support for servers, more model-driven development, and integrated workbench-like applications. The aim is to keep on adding batteries to Tango so that it remains a modern, powerful control system that satisfies not only the needs of light-source facilities but other communities too.

  Over the last two decades EPICS has evolved from a basic set of control applications created for the Ground Test Accelerator to a rich and reliable control system framework installed in more than 120 locations worldwide. The continuous development of EPICS is supported by the worldwide collaboration and coordinated by a set of major laboratories. This procedure ensures continuous quality checking and thus leads to stable production versions. The clear separation of the robust core software on the Input Output Controllers (IOCs) from the channel access protocol and the applications running on workstations and servers allows nearly independent software developments on all three levels. This paper will describe the new developments on the IOC side, which will increase the robustness by adding redundancy or will improve the management and the functionality. This includes the vision of a new Java-based IOC. The support for new data types will bring more flexibility to the channel access protocol. New developments on the application side are clearly indicating that Java and Eclipse (e.g., Control System Studio – CSS, XAL and others) will form the basis for many future applications.

  TINE (Three-fold Integrated Networking Environment) has been the Control System in use at HERA for some time, plays a major role in the Pre-accelerators at DESY, DORIS, FLASH, PITZ (Zeuthen), EMBL-Hamburg, GKSS-Hamburg, PF Beamline (KEK), and is the designated control system for the new third-generation light source PETRA3. TINE has always emphasized both performance and flexibility. For instance, using the multicast capabilities of TINE, state-of-the-art, near real-time video transmission is possible. At the same time, developers have a large toolkit and variety of software solutions at their disposal, and in general on their favorite platform and programming language. Code-generation wizards are available for rapid development of TINE servers, whereas intelligent GUI components such as ACOP(*) aid in the development of either “rich” or “simple” client applications. The most recent major release brought with it a bundle of new features and improvements. We give here an overview of the TINE control system in general, what’s new in particular, and focus on those features not available in other mainstream control systems, such as EPICS or TANGO.

FOPA04 Elements of Control System Longevity 736

  What are the essential architectural elements that are likely to give any particular approach to building controls systems a long tenure? Many aspects can easily be identified by their negative value, such as dependence on particular language(s), operating systems, or particular board/bus technologies. In addition, localizing the human expertise to one sponsoring institution, or even to a specialized controls community, can limit the lifetime. I will argue here that the fundamental positive aspect that gives the greatest endurance is "decoupling, decoupling, decoupling." The principle of decoupling applies in both large and small contexts, both technical and social. I will attempt to show that among the key contributors to achieving this desired state are very stable, very narrow "intellectual" bottlenecks (realized as wire protocols or APIs) at appropriate levels; no requirement for centralized entities (both physical and social); and a high degree of asynchronous communication.

  We were faced with a problem of integrating an XY diffractometer device into an EPICS control system, where the integration into the Tango control system (TANGO Device Server) already existed. We have developed a generic TANGO-to-EPICS translator, which provides the EPICS control system with an interface to an existing TANGO Device Server. An EPICS Asyn driver is used for handling the communication trough library, which is based on the CORBA protocol. The interface provides a generic way for executing commands with different data types as arguments. Attribute manipulation for all major TANGO data types is supported.
