  A control system comprising of the personal computers network and the CAMAC stations for the JAERI Free Electron Laser is designed and is in the development stage. It controls the equipment and analyzes the electron and optical beam experiments. The concept and the prototype of the control system are described. The Free Electron Laser (FEL) facility, SCARLET (Superconducting Accelerator for Research of Light Emission at Tokai), is now under construction at JAERI. It is a first step of the FEL program and the aim is the R&D of the superconducting accelerator (SCA) based FEL system in 10-50 µm range. The SCA is employed due to the suitability for the cw operation in the second phase of the project.

  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.

  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.

  The CERN-MPPC collaboration concentrates its effort on the development of machines based on massive parallelism with thousands of integrated processing elements, arranged in a string. Seven applications are under detailed studies within the collaboration: three for LHC, one for SSC, two for fixed target high energy physics at CERN and one for HDTV. Preliminary results are presented. They show that the objectives should be reached with the use of the ASP architecture.

  Pulse technique applied in the timing and sequencing of the various part of the MUT tokamak system are discussed. The modular architecture of the pulse generating device highlights the versatile application of the simple physical concepts in precise and complicated research experiment. In experimental studies of pulse plasma devices, timing and sequencing of the various events are an important part of the experiment and requires careful considerations. This is achieved in the MUT (University of Malaya Tokamak) tokamak system by employing modular architecture involving various modules of pulse generating devices.

  A mountain view of beam profiles in a synchrotron ring can be taken without any beam destruction by collecting charged particles produced by the circulating beam hitting residual gas in the ring to a sensor. When a rectangular Micro Channel Plate with multi-anodes or lined-up electron multipliers is used as the sensor, the profiles can be measured within one acceleration period, even if the beam intensity is very low and the ring is kept in a high vacuum. We describe this non-destructive profile monitor (NDPM) as well as the momentum spread measurement system by a combination of two sets of NDPM.

  HIMAC is a heavy Ion accelerator facility dedicated to the medical use, especially for the clinical treatment of tumors. The ion species required for the clinical treatment range from 4He to 40Ar. An RF control system of the HIMAC synchrotron has been constructed. In this control system we have adopted a digital feed back system with a digital synthesizer (DS). Combining a high power system, performance of the control system have been tested in a factory (Toshiba) with a simulator circuit of the synchrotron oscillation. Following this test, we had beam acceleration test with this control system at TARN-II in INS (Institute for Nuclear Study, University of Tokyo). This paper describes the RF control system and its tested results.
