Four interrelated projects are underway whose purpose is to migrate the LAMPF-PSR Accelerator Complex control systems to a system with a common set of hardware and software components. Project goals address problems in performance, maintenance and growth potential. Front-end hardware, operator interface hardware and software, computer systems, network systems and data system software are being simultaneously upgraded as part of these efforts. The efforts are being coordinated to provide for a smooth and timely migration to a client-server model-based data acquisition and control system. An increased use of distributed intelligence at both the front-end and the operator interface is a key element of the projects.

S02SRU02	Common Control System for the CERN Accelerators	54
	R. Rausch, Ch. Serre CERN, Meyrin, Switzerland
	The PS and SPS Accelerator Control Systems are becoming obsolete and need urgent rejuvenation. After a control users forum, where users expressed their needs, two main Working Groups were set up, consisting of Control and Equipment Specialists and experienced Machine Operators. One Working Group studied the architecture and the front-end processing and the other a common approach to the application software needed to run the CERN accelerator complex. The paper presents the technical conclusions of their work and the policy to implement it, taking into account the necessity to operate both machines without interruption of the Physics Program.

S02SRU03	New Control Architecture for the SPS Accelerator at CERN	59
	K.H. Kissler, R. Rauschpresenter CERN, Meyrin, Switzerland
	The Control System for the 450 GeV proton accelerator SPS at CERN was conceived and implemented some 18 years ago. The 16 Bit minicomputers with their proprietary operating system and interconnection with a dedicated network do not permit the use of modern workstations, international communication standards and industrial software packages. The upgrading of the system has therefore become necessary. After a short review of the history and the current state of the SPS control system, the paper describes how CERN’s new control architecture, which will be common to all accelerators, will be realized at the SPS. The migration path ensuring a smooth transition to the final system is outlined. Once the SPS upgrade is complete and following some enhancements to the LEP control system, the operator in the SPS/LEP control center will be working in a single uniform control environment.

S02SRU04	The Next Generation Control System of GANIL	65
	T.T. Luong, L. David, E. Lécorché, M. Ulrich GANIL, Caen, France
	The existing computer control system of GANIL is being renewed to fulfil the increasing requirements of the accelerator operation. This medium term major improvement is aiming at providing the physicists with a wider range of ion beams of higher quality under more flexible and reliable conditions. This paper gives a short description of the new control system envisioned. It consists of a three layer distributed architecture federating a VAX6000-410NMS host computer, a real time control system made up of a dual host VAX3800 and workstation based operator consoles, and at the frontend segment: VME and CAMAC processors running under the VAXELN operating system, and programmable logic controllers for local controls. The basic issues with regard to architecture, human interface, information management, etc. are discussed. Lastly, first implementations and operation results are presented.

S02SRU05	Replacement of the ISIS Control System	71
	R.P. Mannix, C.J. Barton, D.M. Brownless, J.C. Kerr RAL, Chilton, Didcot, Oxon, United Kingdom
	In operation since 1985, ISIS is the world’s most powerful pulsed spallation neutron source. The decision has been taken to replace the existing ISIS control system, which has been in use for over ten years. The problems of such a project, given the legacy of processor specific hardware and software are discussed, along with the problems associated with incorporating existing interface hardware into any new system. Present progress using commercial workstation based control software is presented with, an assessment of the benefits and pitfalls of such an approach.

S02SRU06	Upgrading the Control System for the Accelerators at The Svedberg Laboratory	78
	K.J. Gajewski, L. Thuresson, O. Johansson TSL, Uppsala, Sweden
	Two accelerators at The Svedberg Laboratory in Uppsala, the Gustaf Werner cyclotron and the CELSIUS ring, will get a new control system. At present both the cyclotron and the ring have their own control systems based on S99 and PDP11 minicomputers respectively. There are also a number of subsystems which are controlled separately from the standalone PC based consoles (ECR ion source, electron cooler, vacuum system). The goal of the rejuvenation is to integrate all existing control systems and provide the new system with an uniform operators interface based on workstations. The obsolete S99 microcomputers will be substituted with a VME system and all subsystems will be connected to the Ethernet. The upgrade strategy enabling the transformation of the system without any long shut-down period is discussed. Hardware and software planned for the upgrade is presented together with a discussion of expected problems.

S02SRU07	Upgrading the BEPC Control System	82
	L.P. Yang, L.Z. Wangpresenter, S.-Y. Liu IHEP, Beijing, People’s Republic of China
	The BEPC control system has been put into operation and operated normally since the end of 1987. Three years’s experience shows this system can satisfy basically the operation requirements, also exhibits some disadvantages a raised from the original centralized system architecture based on the VAX-VCC-CAMAC, such as slow response, bottle neck of VCC, less CPU power for control etc. This paper describes the method and procedure for upgrading the BEPC control system which will be based on DECnet and DEC-WS, and thus intend to upgrade the control system architecture from the centralized to the distributed and improve the integral system performance.

S02SRU08	The Rejuvenation of TRISTAN Control System	85
	T. Mimashi, J. Urakawa, S.-I. Kurokawa, T. Kawamoto, S. Takeda, A. Akiyama, K. Kudoh, K. Komada, T. Naitoh KEK, Ibaraki, Japan
	The current TRISTAN accelerator control system uses CAMAC as a front end electronics, and they are controlled by twenty five Hitachi minicomputer HIDIC 80’s which are linked with an N-to-N token ring network. After five years from now, these computers must be replaced. This is because of the life time of control system and we have to cope with the requirements imposed by our future project such as the KEK B-Factory and the main ring photon factory projects. The rejuvenation of this control has to be done under some constraints such as the lack of manpower, limited time and financing. First we review the problems of current control system, then the philosophy of the new generation control system is presented. Finally it is discussed how to move to the new generation control system from the current TRISTAN control system.

S02SRU09	Upgrade Plan for the Control System of the KEK e⁻/e⁺ Linac	89
	K. Furukawa, N. Kamikubota, K. Nakahara, I. Abe KEK, Ibaraki, Japan
	The KEK 2.5-GeV linac has been operating since 1982. However, in order to maintain reliable operation, the control system should be upgraded within a few years. We plan to replace the minicomputers and the main network connecting them. Thus, the architecture of the control software will also be revised. In the new system we should adopt software and hardware standards. In the next control system we will employ the TCP/IP (DARPA) protocol suite for the main network and Unix workstations to replace the minicomputers. For connections to the local controllers, VME bus (IEEE 1014) will be utilized.

S02SRU10	The New Control System for TARN-2	93
	S. Watanabe, J. Yoshizawa, T. Katayama INS, Tokyo, Japan K. Aoki, K. Ohnishi SHI, Tokyo, Japan
	The new control system for the cooler-synchrotron, TARN-2, is described. The new control system consists of OPU’s (work stations) and EXU (control computer) linked with the local area network. The text message is used to transfer the control commands and their results. The control program CSA90 at EXU decodes the text message and executes it with the aid of the interface and periodic control subroutines. Both subroutines use common sharable image composed of the status, values, parameters and so on. The CAMAC, GPIB and RS232C are standard interface at EXU.
