S05SRN01	A Control System for a Free Electron Laser Experiment	controls, data-acquisition, software, operation	195
	D. Giove INFN/LASA, Segrate (MI), Italy
	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 λ_r=3 mm, and the possibility of tuning from λ_r= 1 cm to λ_r=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.

S06SA02	Ideas on a Generic Control Systems Based on the Experience on the 4 LEP Experiments Control System	controls, database, software, detector	246
	R. Barillère, J.-M. Le Goff, H. Milcent, R. Stampfli CERN, Meyrin, Switzerland
	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.

S10TS07	The Timing System of the RFX Nuclear Fusion Experiment	timing, software, hardware, operation	367
	V. Schmidt, G. Flor, G. Manduchi, I. Piacentini Consorzio RFX, Associazione Euratom-ENEA sulla Fusione, Padova, Italy V. Schmidt HMI, Berlin, Germany
	The RFX Nuclear Fusion Experiment in Padova, Italy, employs a distributed system to produce precision trigger signals for the fast control of the experiment and for the experiment-wide synchronization of data acquisition channels. The hardware of the system is based on a set of CAMAC modules. The modules have been integrated into a hardware/software system which provides the following features: # generation of pre-programmed timing events, # distribution of asynchronous (not pre-programmed) timing events, # gating of timing event generation by Machine Protection System, # automatic stop of timing sequence in case of highway damage, # dual-speed timebase for transient recorders, # system-wide precision of ¿3 ¿s, time resolution ¿ l0 ¿s. The operation of the timing system is fully integrated into the RFX data acquisition system software. The Timing System Software consists of three layers: the lowest one corresponds directly to the CAMAC modules, the intermediate one provides pseudo-devices which essentially correspond to specific features of the modules (e.g. a dual frequency clock source for transient recorders), the highest level provides system set-up support. The system is fully operational and was first used during the commissioning of the RFX Power Supplies in spring ’91.

S16MS04	Optimization of Accelerator Control	controls, operation, distributed, injection	550
	N.D. Vasiljev, L.V. Mozin, V.A. Shelekhov NIIEFA, St. Petersburg, Russia
	Expensive exploitation of charged particle accelerators is inevitably concerned with requirements of effectively obtaining of the best characteristics of accelerated beams for physical experiments. One of these characteristics is intensity. Increase of intensity is hindered by a number of effects, concerned with the influence of the volume charge field on a particle motion dynamics in accelerator’s chamber. However, ultimate intensity, determined by a volume charge, is almost not achieved for the most of the operating accelerators. This fact is caused by losses of particles during injection, at the initial stage of acceleration and during extraction. These losses are caused by deviations the optimal from real characteristics of the accelerating and magnetic system. This is due to a number of circumstances, including technological tolerances on structural elements of systems, influence of measuring and auxiliary equipment and beam consumers’ installations, placed in the closed proximity to magnets, and instability in operation of technological systems of accelerator. Control task consists in compensation of deviations of characteristics of magnetic and electric fields by optimal selection of control actions. As for technical means, automation of modem accelerators allows to solve optimal control problems in real time. Therefore, the report is devoted to optimal control methods and experimental results.

	In scientific organizations one often encounters the opinion that management is a trivial activity and that project managers enjoy the easy side of the project life, far away from where the real work is. However, examples abound of projects failing to meet their objectives, running behind schedule, overrunning costs, etc., because of poor management. To several aspects which are crucial for the successful completion of a project the attention they deserve has to be paid if the project is to meet its objectives within the constraints that are imposed upon it. Whereas the engineers do things, the manager gets things done; managers are particularly concerned with: # what is planned to be done: i.e. the product which should be delivered, in our case the control system, # how long will the project take: i.e. schedule, # how one will know when the project is finished: completion criteria, # how much will it cost to implement and to maintain: Le. the cost. These issues have been discussed in the panel discussion.

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.

The RFX Nuclear Fusion Experiment in Padova, Italy, employs a distributed system to produce precision trigger signals for the fast control of the experiment and for the experiment-wide synchronization of data acquisition channels. The hardware of the system is based on a set of CAMAC modules. The modules have been integrated into a hardware/software system which provides the following features: # generation of pre-programmed timing events, # distribution of asynchronous (not pre-programmed) timing events, # gating of timing event generation by Machine Protection System, # automatic stop of timing sequence in case of highway damage, # dual-speed timebase for transient recorders, # system-wide precision of ¿3 ¿s, time resolution ¿ l0 ¿s. The operation of the timing system is fully integrated into the RFX data acquisition system software. The Timing System Software consists of three layers: the lowest one corresponds directly to the CAMAC modules, the intermediate one provides pseudo-devices which essentially correspond to specific features of the modules (e.g. a dual frequency clock source for transient recorders), the highest level provides system set-up support. The system is fully operational and was first used during the commissioning of the RFX Power Supplies in spring ’91.

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.

Expensive exploitation of charged particle accelerators is inevitably concerned with requirements of effectively obtaining of the best characteristics of accelerated beams for physical experiments. One of these characteristics is intensity. Increase of intensity is hindered by a number of effects, concerned with the influence of the volume charge field on a particle motion dynamics in accelerator’s chamber. However, ultimate intensity, determined by a volume charge, is almost not achieved for the most of the operating accelerators. This fact is caused by losses of particles during injection, at the initial stage of acceleration and during extraction. These losses are caused by deviations the optimal from real characteristics of the accelerating and magnetic system. This is due to a number of circumstances, including technological tolerances on structural elements of systems, influence of measuring and auxiliary equipment and beam consumers’ installations, placed in the closed proximity to magnets, and instability in operation of technological systems of accelerator. Control task consists in compensation of deviations of characteristics of magnetic and electric fields by optimal selection of control actions. As for technical means, automation of modem accelerators allows to solve optimal control problems in real time. Therefore, the report is devoted to optimal control methods and experimental results.

In scientific organizations one often encounters the opinion that management is a trivial activity and that project managers enjoy the easy side of the project life, far away from where the real work is. However, examples abound of projects failing to meet their objectives, running behind schedule, overrunning costs, etc., because of poor management. To several aspects which are crucial for the successful completion of a project the attention they deserve has to be paid if the project is to meet its objectives within the constraints that are imposed upon it. Whereas the engineers do things, the manager gets things done; managers are particularly concerned with: # what is planned to be done: i.e. the product which should be delivered, in our case the control system, # how long will the project take: i.e. schedule, # how one will know when the project is finished: completion criteria, # how much will it cost to implement and to maintain: Le. the cost. These issues have been discussed in the panel discussion.
