| S04SRS03 | Status of the Control and Beam Diagnostic Systems of the CRYRING Project | controls, timing, hardware, diagnostics | 167 |
|
|||
| CRYRING is a facility for research in atomic, molecular and nuclear physics. It uses a cryogenic electron beam ion source, CRYSIS, together with an RFQ linear accelerator as injector into a synchrotron/storage ring for very highly charged, heavy ions. The first circulating beam was achieved in December 1990. The status of the systems for control and beam diagnostics are described. | |||

| S05SRN04 | Distributed Control and Data Acquisition for the EUROGAM Gamma Ray Spectrometer | controls, software, interface, data-acquisition | 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. | |||

| S06SA02 | Ideas on a Generic Control Systems Based on the Experience on the 4 LEP Experiments Control System | controls, database, software, experiment | 246 |
|
|||
| Most of the large slow control systems in the LEP collider experiments are distributed heterogeneous and multi-standard. But in spite of the appearances, they have a lot in common. From our direct experience on the L-3 slow control system and from the informations we obtained on the 3 other LEP experiments control systems we have come to the conclusion that it should be possible to build a Generic Control Package from which any control system could be derived. This software package is entirely based on relational databases and is intended to provide all the necessary tools to build a modular, coherent, easy to update and to maintain control system. Among other things this package should include user friendly interfaces, expert systems, and powerful graphic monitoring and control tools. This paper will present our general ideas about the realization of such a package. | |||

| S09DPP03 | Intelligent Trigger by Massively Parallel Processors for High Energy Physics Experiments | electron, target, hadron, experiment | 340 |
|
|||
| 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. | |||

| S10TS08 | An Optical Fiber Phase Lock Network of a Radio Interferometer | network, controls, linac, gun | 371 |
|
|||
| A new phase-lock network using fiber-optic system was developed as a local signal distribution system for 84 antennas of the Nobeyama Radioheliograph. This network is an open loop system and consists of a master oscillator with an E/O converter, an 1-to-84 optical divider, phase stable optical fiber cables and phase stable phase-locked oscillators with O/E converters. Phase stability of the network and phase noise generated at the O/E converter are discussed. This phase-lock network insures the required phase stability of 3°/6 hours. The phase noise increases the coherent loss of 0.1 % at the correlator output, which is very low. This is the first large application of fiber optic devices to an open loop phase-lock network. Our system is very simple and phase-stable. Therefore, it is suitable to the connected array with large number of antennas. | |||

| S11LLC07 | The KEK PS Fast Beam Loss Monitor System | hardware, controls, booster, acceleration | 395 |
|
|||
| The higher beam intensities now being accelerated in the KEK proton synchrotron (PS) complex have increased the importance of observing the beam loss during acceleration. The beam loss should be continuously monitored to minimize radiation damage to the accelerator components. A fast loss monitor also is a good tool for observing where and when the beam is lost, by which we are able to get information on the beam dynamics. The development of a fast beam loss monitor system at KEK is described in this paper. | |||

| S12FC05 | PLS Beam Position Measurement and Feedback System | real-time, feedback, closed-orbit, controls | 427 |
|

|
Funding: Work supported by Pohang Iron & Steel Co., Ltd. (POSCO) and Ministry of Science and Technology (MOST), Government of Republic of Korea. A real-time orbit correction system is proposed for the stabilization of beam orbit and photon beam positions in Pohang Light Source. PLS beam position monitor system is designed to be VMEbus compatible to fit the real-time digital orbit feedback system. A VMEbus based subsystem control computer, Mil-1553B communication network and 12 BPM/PS machine interface units constitute digital part of the feedback system. With the super-stable PLS correction power supply, power line frequency noise is almost filtered out and the dominant of beam orbit fluctuations are expected to appear below 15 Hz. DSP board in SCC for the computation and using an appropriate compensation circuit for the phase delay by the vacuum chamber, PLS real-time orbit correction system is realizable without changing the basic structure of PLS computer control system. |
