S01SRA01 A Users View of the SPS and LEP Control Systems 1

  Every accelerator has a control system; at present the SPS has two, both of which are needed to run the machine. Consequently a user of the SPS I LEP complex has to be concurrently familiar with three control systems. While this situation brings problems it allows, even forces, comparison between the different systems, which in tum enriches the user viewpoint. This paper assesses the SPS and LEP control systems from the point of view of the user, who may be an equipment specialist, operator, accelerator physicist or combinations thereof.

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.

The SLC control system is the dynamic result of a number of forces. The most obvious force is the functional requirements of the SLC itself, but other forces are history, budget, people, available technology, etc. The plan of this paper is to describe the critical functional requirements of the SLC which caused significant development of the control system. I have tried to focus on functional requirements as a driver, and I will describe some solutions which we have implemented to satisfy those requirements. The important functional requirements drivers for the control system discussed in this paper are: Repetition rate, Sensitivity to orbit distortion, Stability/Automation, and Accelerator Development

  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.

  This paper presents recent developments of the control system for ALPI, the new superconducting linear accelerator that will begin to operate at L.N.L. next year. Both hardware and software architectures are described and some base choices are discussed. Results of tests performed in the last two years are also reported.

S01SRA07 The GSI Control System 27
 
  • U. Krause, V.RW. Schaapresenter, R. Steiner
    GSI, Darmstadt, Germany
 
  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.

  Three accelerator facilities were built in the past few years, the 2.8 GeV electron positron collider BEPC, the heavy ion SSC cyclotron accelerator HIRFL and the 800 MeV synchrotron radiation storage ring HESYRL. Aimed at different research areas, they represent a new generation of accelerator in China. This report describes the design philosophy, the structure, performance as well as future improvements of the control systems of the these facilities.

  HESYRL synchrotron radiation storage ring was completed in 1989 and has been in commissioning since then. Now it has met its design specification and is ready for synchrotron light experiments. Control system of the project was completed in 1989 and some modifications were made during commissioning. This paper describes its present configuration, status and upgrading plan.

  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 47
 
  • V.M. Kotov, R.A. Posepresenter

  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.
