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, interface, real-time, high-voltage | 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. | |||

| S05SRN01 | A Control System for a Free Electron Laser Experiment | controls, experiment, software, operation | 195 |
|
|||
| The general layout of a control and data acquisition system for a Free Electron Laser experiment will be discussed. Some general considerations about the requirements and the architecture of the whole system will be developed. The aim or the ELFA (Electron Laser Facility) experiment is to study the physics of a single pass FEL amplifier operating in the high gain Compton regime using a short electron pulse beam. The experimental purpose is the production of high peak power (0.3-1 GW) of microwave radiation, with a basic wavelength of λr=3 mm, and the possibility of tuning from λr= 1 cm to λr=0.1 mm. In order to achieve this goal an electron beam of very high current (400 A) in short pulses (6 cm) and with a maximum energy around 10 MeV will be injected into the wiggler midplane. | |||

| S05SRN04 | Distributed Control and Data Acquisition for the EUROGAM Gamma Ray Spectrometer | controls, software, detector, interface | 208 |
|
|||
| 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. | |||

| S05SRN09 | Control and Monitoring System Design Study for the UNK Experimental Setups | electron, electronics, controls, experiment | 232 |
|
|||
| At present a number of experimental setups for the new UNK project are under construction. A common approach to the architecture of control/DAO/trigger systems will be used in the development of electronics for all these detectors. The system analysis and design group has been formed for this purpose. The group activity is aimed at the development of such unified system. The group has started with control and monitoring system as one of the most important parts and the environment for the DAO/trigger systems. The group activity status report is presented. | |||

| S06SA01 | Overview of the Next Generation of Fermilab Collider Software | Windows, controls, interface, collider | 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.

| S06SA05 | A VMEbus General-Purpose Data Acquisition System | controls, monitoring, interface, 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.

| S11LLC09 | A CAMAC-Resident Microprocessor for the Monitoring of Polarimeter Spin States | controls, operation, cyclotron, experiment | 403 |
|
|||
| A CAMAC module for the reporting of polarimeter spin states is being developed using a resident microcontroller. The module will allow experimenters at the Indiana University Cyclotron Facility to monitor spin states and correlate spin information with other experimental data. The use of a microprocessor allows for adaptation of the module as new requirements ensue without change to the printed circuit board layout. | |||

| S14OOP06 | The State Manager: A Tool to Control Large Data-Acquisition Systems | controls, interface, 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. | |||
