	CERN’s planned large su­per­con­duct­ing col­lider pro­ject pre­sents sev­eral new chal­lenges to the Con­trol Sys­tem. These are dis­cussed along with cur­rent think­ing as to how they can be met. The high field su­per­con­duct­ing mag­nets are sub­ject to "per­sis­tent cur­rents" which will re­quire real time mea­sure­ments and con­trol using a math­e­mat­i­cal model on a 2-10 sec­ond time in­ter­val. This may be re­alised using di­rect links, mul­ti­plexed using TDM, be­tween the field equip­ment and cen­tral servers. Quench con­trol and avoid­ance will make new de­mands on speed of re­sponse, re­li­a­bil­ity and sur­veil­lance. The in­te­gra­tion of large quan­ti­ties of in­dus­tri­ally con­trolled equip­ment will be im­por­tant. Much of the con­trols will be in com­mon with LEP so a seam­less in­te­gra­tion of LHC and LEP con­trols will be sought. A very large amount of new high-tech equip­ment will have to be tested, as­sem­bled and in­stalled in the LEP tun­nel in a short time. The man­power and cost con­straints will be much tighter than pre­vi­ously. New ap­proaches will have to be found to solve many of these prob­lems, with the ad­di­tional con­straint of in­te­grat­ing them into an ex­ist­ing frame­work.

	Funding: Operated by the Universities Research Association, Inc., for the U.S. Department of Energy under Contract No. DE-AC02-89ER40486. This paper pre­sents the re­sults of analy­sis of the per­for­mance re­quire­ments of the Su­per­con­duct­ing Super Col­lider Con­trol Sys­tem. We quan­tify the per­for­mance re­quire­ments of the sys­tem in terms of re­sponse time, through­put and re­li­a­bil­ity. We then ex­am­ine the ef­fect of dis­tance and traf­fic pat­terns on con­trol sys­tem per­for­mance and ex­am­ine how these fac­tors in­flu­ence the im­ple­men­ta­tion of the con­trol net­work ar­chi­tec­ture and com­pare the pro­posed sys­tem against those cri­te­ria.

S03SRD03	The Computer Control System for the CESR B Factory	110
	C.R. Strohman, S.B. Peck, D.H. Rice Cornell University (CLASSE), Cornell Laboratory for Accelerator-Based Sciences and Education, Ithaca, New York, USA
	Funding: Work supported by the US National Science Foundation B fac­to­ries pre­sent unique re­quire­ments for con­trols and in­stru­men­ta­tion sys­tems. High re­li­a­bil­ity is crit­i­cal to achiev­ing the in­te­grated lu­mi­nos­ity goals. The CESR-B up­grade at Cor­nell Uni­ver­sity will have a con­trol sys­tem based on the ar­chi­tec­ture of the suc­cess­ful CESR con­trol sys­tem, which uses a cen­tral­ized data­base/mes­sage rout­ing sys­tem in a mul­ti­ported mem­ory, and VAXs­ta­tions for all high-level con­trol func­tions. The im­ple­men­ta­tion of this ar­chi­tec­ture will ad­dress the de­fi­cien­cies in the cur­rent im­ple­men­ta­tion while pro­vid­ing the re­quired per­for­mance and re­li­a­bil­ity.

S03SRD04	Standards and the Design of the Advanced Photon Source Control System	116

	Funding: Work supported by U.S. Department of Energy, Office of Basic Energy Sciences under Contract No. W-31-109-ENG-38. The Ad­vanced Pho­ton Source (APS), now under con­struc­tion at Ar­gonne Na­tional Lab­o­ra­tory (ANL), is a 7 GeV positron stor­age ring ded­i­cated to re­search fa­cil­i­ties using syn­chro­tron ra­di­a­tion. This ring, along with its in­jec­tion ac­cel­er­a­tors is to be con­trolled and mon­i­tored with a sin­gle, flex­i­ble, and ex­pand­able con­trol sys­tem. In the con­cep­tual stage the con­trol sys­tem de­sign group faced the chal­lenges that face all con­trol sys­tem de­sign­ers: (1) to force the ma­chine de­sign­ers to quan­tify and cod­ify the sys­tem re­quire­ments, (2) to pro­tect the in­vest­ment in hard­ware and soft­ware from rapid ob­so­les­cence, and (3) to find meth­ods of quickly in­cor­po­rat­ing new gen­er­a­tions of equip­ment and re­place ob­so­lete equip­ment with­out dis­rupt­ing the ex­ist­ing sys­tem. To solve these and re­lated prob­lems, the APS con­trol sys­tem group made an early res­o­lu­tion to use stan­dards in the de­sign of the sys­tem. This paper will cover the pre­sent sta­tus of the APS con­trol sys­tem as well as dis­cuss the de­sign de­ci­sions which led us to use in­dus­trial stan­dards and col­lab­o­ra­tions with other lab­o­ra­to­ries when­ever pos­si­ble to de­velop a con­trol sys­tem.

S03SRD05	The ESRF Control System; Status and Highlights	121
	W.D. Klotz ESRF, Grenoble, France
	The Eu­ro­pean Syn­chro­tron Ra­di­a­tion Fa­cil­ity (ESRF) will op­er­ate a 6 GeV e⁻/e⁺ stor­age ring of 850 m cir­cum­fer­ence to de­liver to date un­prece­dented high bril­liance X-rays to the Eu­ro­pean re­search com­mu­nity. The ESRF is the first mem­ber of a new gen­er­a­tion of Syn­chro­tron Ra­di­a­tion Sources, in which the bril­liance of the beam and the uti­liza­tion of in­ser­tion de­vices are pushed to their pre­sent lim­its. Com­mis­sion­ing of the fa­cil­ity’s stor­age ring will start in spring 1992. A full en­ergy in­jec­tor, con­sist­ing of a 200 MeV lin­ear prein­jec­tor and a 6GeV fast cy­cling syn­chro­tron (l0 Hz) of 350 m cir­cum­fer­ence have been suc­cess­fully com­mis­sioned dur­ing the last months. The ma­chine con­trol sys­tem for this fa­cil­ity, which is under con­struc­tion since 1988, is still under de­vel­op­ment, but its ini­tial on-site op­er­a­tion this year has clearly made eas­ier the com­mis­sion­ing of the prein­jec­tor plant. A de­scrip­tion of the cur­rent sys­tem is given and ap­pli­ca­tion soft­ware for start-up is briefly de­scribed.

	We de­scribe the sta­tus of the DANTE (DA¿NE New Tools En­vi­ron­ment) con­trol sys­tem for the new DA{Φ}NE {Φ}-fac­tory under con­struc­tion at the Fras­cati Na­tional Lab­o­ra­to­ries. The sys­tem is based on a cen­tral­ized com­mu­ni­ca­tion ar­chi­tec­ture for sim­plic­ity and re­li­a­bil­ity. A cen­tral proces­sor unit co­or­di­nates all com­mu­ni­ca­tions be­tween the con­soles and the lower level dis­trib­uted pro­cess­ing power, and con­tin­u­ously up­dates a cen­tral mem­ory that con­tains the whole ma­chine sta­tus. We have de­vel­oped a sys­tem of VME Fiber Optic in­ter­faces al­low­ing very fast point to point com­mu­ni­ca­tion be­tween dis­tant proces­sors. Mac­in­tosh II per­sonal com­put­ers are used as con­soles. The lower lev­els are all built using the VME stan­dard.

	The upper level of a dis­trib­uted con­trol sys­tem de­signed for the su­per­con­duct­ing Cy­clotron (SC), will be dis­cussed. In par­tic­u­lar, we will pre­sent a de­tailed de­scrip­tion of the op­er­a­tor view of this ac­cel­er­a­tor along with the tools for I/O points man­age­ment, data rap­p­re­sen­ta­tions, data archiv­ing and re­trieval. A ded­i­cated pro­gram, de­vel­oped by us, work­ing under X-Win­dow will be de­scribed as a start­ing point for a new man-ma­chine in­ter­face ap­proach in small lab­o­ra­to­ries op­posed to the first in­dus­trial avail­able pack­ages.

	The IHEP pro­ton Ac­cel­er­at­ing and Stor­age Com­plex (UNK) in­cludes in its first stage a 400 GeV con­ven­tional and a 3000 GeV su­per­con­duct­ing ring placed in the same un­der­ground tun­nel of 20.7 km cir­cum­fer­ence. The beam will be in­jected into UNK from the ex­ist­ing 70 GeV ac­cel­er­a­tor U-70. The ex­per­i­men­tal pro­gramme which is planned to start in 1995, will in­clude 3000 GeV fixed tar­get and 400-3000 GeV col­lid­ing beams physics. The size and com­plex­ity of the UNK dic­tate a dis­trib­uted mul­ti­proces­sor ar­chi­tec­ture of the con­trol sys­tem. About 4000 of 8/16 bit con­trollers, di­rectly at­tached to the UNK equip­ment will per­form low level con­trol and data ac­qui­si­tion tasks. The equip­ment con­trollers will be con­nected via the MIL-1553 field bus to VME based 32-bit front end com­put­ers. The TCP/IP net­work will in­ter­con­nect front end com­put­ers in the UNK equip­ment build­ings with UNIX work­sta­tions and servers in the Main Con­trol Room. The re­port pre­sents the gen­eral ar­chi­tec­ture and cur­rent sta­tus of the UNK con­trol.

S03SRD09	Moscow University Race-Track Microtron Control System: Ideas and Development	140
	A.S. Chepurnov, I.V. Gribov, S.Yu. Morozov, A.V. Shumakov, S.V. Zinoviev MSU, Moscow, Russia
	Moscow Uni­ver­sity race-track mi­cro­tron (RTM) con­trol sys­tem is a star-shape net­work of LSI-11 com­pat­i­ble mi­cro­com­put­ers. Each of them is con­nected with RTM sys­tems via CAMAC; op­ti­cal fiber cou­pling is also used. Con­trol sys­tem soft­ware is de­signed on Pas­cal-1, sup­ple­mented with real time mod­ules and Macro. A uni­fied real time tech­nique and re-en­ter­able data ac­qui­si­tion dri­vers allow to sim­plify de­vel­op­ment of con­trol dri­vers and al­go­rithms. Among the lat­ter three main types are used: DDC meth­ods, those, based on op­ti­miza­tion tech­nique and al­go­rithms, ap­ply­ing mod­els of mi­cro­tron’s sys­tems. Man-ma­chine in­ter­face is based on con­cept of the "world of ac­cel­er­a­tor". It sup­ports means to de­sign, within hard­ware pos­si­bil­i­ties, var­i­ous com­puter im­ages of the RTM.

S03SRD10	Present Status of Control System at the SRRC	143
	G.J. Jan, J. Chen, C.J. Chen, C.S. Wang NSRRC, Hsinchu, Taiwan C.S. Wang NTUT, Taipei, Taiwan
	The mod­ern con­trol tech­nique was used to de­sign and set up a con­trol sys­tem for the syn­chro­tron ra­di­a­tion fa­cil­i­ties at the syn­chro­tron ra­di­a­tion re­search cen­ter (SRRC). This con­trol sys­tem will be fi­nally to op­er­ate the ded­i­cated ma­chine to pro­vide the 1.3 GeV syn­chro­tron ra­di­a­tion light. The con­trol sys­tem will con­trol and mon­i­tor the com­po­nents of stor­age ring, beam trans­port and in­jec­tor sys­tem. The con­cept of the phi­los­o­phy is to de­sign a unique, sim­ple struc­ture and ob­ject-ori­ented graphic dis­play con­trol sys­tem. The SRRC con­trol sys­tem has the major fea­tures such as two level ar­chi­tec­ture, high speed local area net­work with high level pro­to­col, high speed mi­cro­proces­sor based VME crate, ob­ject-ori­ented high per­for­mance con­trol con­sole and graphic dis­play. The com­puter hard­ware sys­tem was set up and tested. The soft­ware in top level com­put­ers which in­clude data­base server, net­work server, up­load pro­gram, data ac­cess pro­gram, alarm check­ing and dis­play, as well as graph­ics user in­ter­face (GUI) pro­gram were de­vel­oped and tested.

S03SRD11	Status Report on Control System Development for PLS	147
	S.C. Won, S.-S. Chang, J. Huang, J.W. Lee, J. Lee, J.H. Kirn PAL, Pohang, Kyungbuk, Republic of Korea
	Funding: Work supported by Pohang Iron & Steel Co., Ltd. (POSCO) and Ministry of Science and Technology (MOST), Government of Republic of Korea. Em­pha­siz­ing re­li­a­bil­ity and flex­i­bil­ity, hi­er­ar­chi­cal ar­chi­tec­ture with dis­trib­uted com­put­ers have been de­signed into the Po­hang Light Source (PLS) com­puter con­trol sys­tem. The PLS con­trol sys­tem has four lay­ers of com­puter sys­tems con­nected via mul­ti­ple data com­mu­ni­ca­tion net­works. This paper pre­sents an overview of the PLS con­trol sys­tem. The ac­cel­er­a­tor con­trol sys­tem pro­vides means for ac­cess­ing all ma­chine com­po­nents so that the whole sys­tem could be mon­i­tored and con­trolled re­motely. These tasks in­clude set­ting mag­net cur­rents, col­lect­ing sta­tus data from the vac­uum sub­sys­tem, tak­ing orbit data with beam po­si­tion mon­i­tors, feed­back con­trol of elec­tron beam orbit, reg­u­lat­ing the safety in­ter­lock mon­i­tors, and so forth. To de­sign a con­trol sys­tem which can per­form these func­tions sat­is­fac­to­rily, cer­tain basic de­sign re­quire­ments must be ful­filled. Among these are re­li­a­bil­ity, ca­pa­bil­ity, expa.​nsibility, cost con­trol, and ease of op­er­a­tion.

S03SRD12	Design of SPring-8 Control System	151
	T. Wada, T. Kumahara, H. Yonehara, H. Yoshikawa, T. Masuda, W. Zhen JAERI-RIKEN/Spring-8 Project Team, Tokyo, Japan
	The con­trol sys­tem of SPring-8 fa­cil­ity is de­signed. A dis­trib­uted com­puter sys­tem is adopted with a three-hi­er­ar­chy lev­els. All the com­put­ers are linked by com­puter net­works. The net­work of upper level is a high-speed multi-me­dia LAN such as FDDI which links sub-sys­tem con­trol com­put­ers, and mid­dle are Eth­er­net or MAP net­works which link front end proces­sors (FEP) such as VME sys­tem. The low­est is a field level bus which links VME and con­trolled de­vices. Work­sta­tions (WS) or X-ter­mi­nals are use­ful for man-ma­chine in­ter­faces. For op­er­at­ing sys­tem (OS), UNIX is use­ful for upper level com­put­ers, and real-time OS’s for FEP’s. We will se­lect hard­wares and OS of which spec­i­fi­ca­tions are close to in­ter­na­tional stan­dards. Since re­cently the cost of soft­ware has be­come higher than that of hard­ware, we in­tro­duce com­puter aided tools as many as pos­si­ble for pro­gram de­vel­op­ments.

S03SRD13	Design of a Control System of the Linac for SPring-8	154
	H. Yoshikawa, Y.I. Itoh, T. Kumahara JAERI, Tokai-Mura, Naka-Gun, Ibaraki-Ken, Japan
	The de­sign of a con­trol sys­tem of the linac which is a large scale sys­tem in­clud­ing many un­sta­ble com­po­nents like kly­strons and mod­u­la­tora. The linac for SPring-8 re­quires to be op­er­ated au­to­mat­i­cally for in­jec­tion to the syn­chro­tron. Under these con­di­tions, we chose a dis­trib­uted con­trol sys­tem ar­chi­tec­ture of a sin­gle layer net-work to sim­plify the pro­to­col of the net-work be­tween the linac, the booster syn­chro­tron and the stor­age ring. A VME com­puter of 68030 is put in every mod­u­la­tor of the linac, and all con­trol sig­nals are gath­ered to the near­est VME com­puter. OS-9 and OS-9000 are on trial for in­ves­ti­ga­tion of the per­for­mances. TCP/IP is ten­ta­tively cho­sen as a pro­to­col of the net-work, but we ex­pect that MAP/MMS makes a high per­for­mance, and we are prepar­ing a test of it.

	A con­trol sys­tem for HIMAC syn­chro­tron has been de­signed. The sys­tem con­sists of a main com­puter, con­sole work­sta­tions, a few small com­put­ers and VME-com­put­ers con­nected via Eth­er­net. The small com­put­ers are ded­i­cated to the con­trol of an in­jec­tion line, an ex­trac­tion line and an RF sys­tem. Power sup­plies in main rings are con­trolled by the VME-com­put­ers through FDI/FDO, DI/DO mod­ules. This paper de­scribes an overview of the syn­chro­tron con­trol sys­tem.
