  Su­perKEKB elec­tron-positron asym­met­ric col­lid­er is being con­struct­ed after a decade of suc­cess­ful op­er­a­tion at KEKB for B physics re­search. KEKB com­plet­ed all of the tech­ni­cal mile­stones, and had of­fered im­por­tant in­sights into the fla­vor struc­ture of el­e­men­tary par­ti­cles, es­pe­cial­ly the CP vi­o­la­tion. The com­bi­na­tion of script­ing lan­guages at the op­er­a­tion layer and EPICS at the equip­ment layer had led the con­trol sys­tem to suc­cess­ful per­for­mance. The new con­trol sys­tem in Su­perKEKB will con­tin­ue to em­ploy those major fea­tures of KEKB, with ad­di­tion­al tech­nolo­gies for the re­li­a­bil­i­ty and flex­i­bil­i­ty. The major struc­ture will be main­tained es­pe­cial­ly the on­line link­age to the sim­u­la­tion code and slow con­trols. How­ev­er, as the de­sign lu­mi­nos­i­ty is 40-times high­er than that of KEKB, sev­er­al or­ders of mag­ni­tude high­er per­for­mance will be re­quired at cer­tain area. At the same time more con­trollers with em­bed­ded tech­nol­o­gy will be in­stalled to meet the lim­it­ed re­sources.

  De­sign and im­ple­men­ta­tion of image ac­qui­si­tion and anal­y­sis is in pro­ceed­ing for the Tai­wan Pho­ton Source (TPS) di­ag­nos­tic ap­pli­ca­tions. The op­ti­cal sys­tem con­tains screen, lens, and light­ing sys­tem. A CCD cam­era with Gi­ga­bit Eth­er­net in­ter­face (GigE Vi­sion) will be a stan­dard image ac­qui­si­tion de­vice. Image ac­qui­si­tion will be done on EPICS IOC via PV chan­nel and anal­y­sis the prop­er­ties by using Mat­lab tool to eval­u­ate the beam pro­file (σ), beam size po­si­tion and tilt angle et al. The EPICS IOC in­te­grat­ed with Mat­lab as a data pro­cess­ing sys­tem is not only could be used in image anal­y­sis but also in many types of equip­ment data pro­cess­ing ap­pli­ca­tions. Progress of the pro­ject will be sum­ma­rized in this re­port.

With­in ac­cel­er­a­tor con­trol sys­tems fast and ac­cu­rate beam dy­nam­ics sim­u­la­tion pro­grams can ad­van­ta­geous­ly as­sist the op­er­a­tors to get a more de­tailed in­sight into the ac­tu­al ma­chine sta­tus. The V-Code sim­u­la­tion tool im­ple­ment­ed at TEMF is a fast track­ing code based on the Vlasov equa­tion. In­stead of di­rect­ly solv­ing this par­tial dif­fer­en­tial equa­tion the con­sid­ered par­ti­cle dis­tri­bu­tion func­tion is rep­re­sent­ed by a dis­crete set of char­ac­ter­is­tic mo­ments. The ac­cu­ra­cy of this ap­proach is ad­justable with the help of the con­sid­ered order of mo­ments and by rep­re­sent­ing the par­ti­cle dis­tri­bu­tion through mul­ti­ple sets of mo­ments in a mul­ti-en­sem­ble en­vi­ron­ment. In this con­tri­bu­tion an overview of the nu­mer­i­cal model is pre­sent­ed to­geth­er with im­ple­ment­ed fea­tures for its ded­i­cat­ed in­te­gra­tion into the con­trol sys­tem of the Su­per­con­duct­ing Lin­ear Ac­cel­er­a­tor S-DALINAC.

The Los Alam­os Neu­tron Sci­ence Cen­ter (LAN­SCE) lin­ear ac­cel­er­a­tor drives user fa­cil­i­ties for iso­tope pro­duc­tion, pro­ton ra­dio­g­ra­phy, ul­tra-cold neu­trons, weapons neu­tron re­search and var­i­ous sci­ences using neu­tron scat­ter­ing. The LAN­SCE Con­trol Sys­tem (LCS), which is in part 30 years old, pro­vides con­trol and data mon­i­tor­ing for most de­vices in the linac and for some of its as­so­ci­at­ed ex­per­i­men­tal-area beam lines. In Fis­cal Year 2011, the con­trol sys­tem went through an up­grade pro­cess that af­fect­ed dif­fer­ent areas of the LCS. We im­proved our net­work in­fras­truc­ture and we con­vert­ed part of our front-end con­trol sys­tem hard­ware to Allen Bradley Con­trol­sLogix 5000 and Na­tion­al In­stru­ments Com­pact RIO pro­grammable au­toma­tion con­troller (PAC). In this paper, we will dis­cuss what we have done, what we have learned about up­grad­ing the ex­ist­ing con­trol sys­tem, and how this will af­fect our fu­ture planes.

  The cur­rent op­er­a­tion soft­ware at GSI con­trol­ling the linac, beam trans­fer lines, syn­chrotron and stor­age ring, has been de­vel­oped over a pe­ri­od of more than two decades using Open­VMS now on Al­pha-Work­sta­tions. The GSI ac­cel­er­a­tor fa­cil­i­ties will serve as a in­jec­tor chain for the new FAIR ac­cel­er­a­tor com­plex for which a con­trol sys­tem is cur­rent­ly de­vel­oped. To en­able reuse and in­te­gra­tion of parts of the dis­tribut­ed GSI soft­ware sys­tem, in par­tic­u­lar the linac op­er­a­tion soft­ware, with­in the FAIR con­trol sys­tem, the cor­re­spond­ing soft­ware com­po­nents must be mi­grat­ed to Linux. The in­ter­op­er­abil­i­ty with FAIR con­trols ap­pli­ca­tions is achieved by adding a gener­ic mid­dle­ware in­ter­face ac­ces­si­ble from Java ap­pli­ca­tions. For port­ing ap­pli­ca­tions to Linux a set of li­braries and tools has been de­vel­oped cov­er­ing the nec­es­sary Open­VMS sys­tem func­tion­al­i­ty. Cur­rent­ly, core ap­pli­ca­tions and ser­vices are al­ready port­ed or rewrit­ten and func­tion­al­ly test­ed but not in op­er­a­tional usage. This paper pre­sents the cur­rent sta­tus of the pro­ject and con­cepts for putting the mi­grat­ed soft­ware into op­er­a­tion.

  J-PARC ac­cel­er­a­tor com­plex com­pris­es Linac, 3-GeV RCS (Rapid Cycle Syn­chrotron), and 30-GeV MR (Main Ring). The J-PARC is a joint pro­ject be­tween JAEA and KEK. Two con­trol sys­tems, one for Linac and RCS and an­oth­er for MR, were de­vel­oped by two in­sti­tutes. Both con­trol sys­tems use the EPICS toolk­it, thus, in­ter-op­er­a­tion be­tween two sys­tems is pos­si­ble. After the first beam in Novem­ber, 2006, beam com­mis­sion­ing and op­er­a­tion have been suc­cess­ful. How­ev­er, op­er­a­tion ex­pe­ri­ence shows that two con­trol sys­tems often make op­er­a­tors dis­tressed: for ex­am­ple, dif­fer­ent GUI look-and-feels, sep­a­rat­ed alarm screens, in­de­pen­dent archive sys­tems, and so on. Con­sid­er­ing de­mands of fur­ther power up­grade and longer beam de­liv­ery, we need some­thing new, which is easy to un­der­stand for op­er­a­tors. It is es­sen­tial to im­prove re­li­a­bil­i­ty of op­er­a­tion. We, two con­trol groups, start­ed to dis­cuss fu­ture di­rec­tions of our con­trol sys­tems. Ideas to de­vel­op com­mon GUI screens of sta­tus and alarms, and to de­vel­op in­ter­faces to con­nect archive sys­tems to each other, are dis­cussed. Progress will be re­port­ed.

  The KEK in­jec­tor linac pro­vides beams with four dif­fer­ent rings: a KEKB high-en­er­gy ring (HER; 8 GeV/elec­tron), a KEKB low-en­er­gy ring (LER; 3.5 GeV/positron), a Pho­ton Fac­to­ry ring (PF; 2.5 GeV/elec­tron), and an Ad­vanced Ring for Pulse X-rays (PF-AR; 3 GeV/elec­tron). For the three rings ex­cept PF-AR, the si­mul­ta­ne­ous top-up in­jec­tion has been com­plet­ed since April 2009. In the si­mul­ta­ne­ous top-up op­er­a­tion, the com­mon DC mag­net set­tings are uti­lized for the beams with dif­fer­ent en­er­gies and amount of charges, where­as the dif­fer­ent op­ti­mized set­tings of RF tim­ing and phase are ap­plied to each beam ac­cel­er­a­tion by using a fast low-lev­el RF (LLRF) phase and trig­ger delay con­trol up to 50 Hz. The non-de­struc­tive beam po­si­tion mon­i­tor (BPM) is an in­dis­pens­able di­ag­nos­tic tool for the sta­ble beam op­er­a­tion. In the KEK Linac, ap­prox­i­mate­ly nine­teen BPMs with the strip-line type elec­trodes are used for the beam orbit mea­sure­ment and feed­back. In ad­di­tion, some of them are also used for the beam en­er­gy feed­back loops. The cur­rent DAQ sys­tem con­sists of the dig­i­tal os­cil­lo­scopes (Tek­tron­ix DPO7104, 10 GSa/s). A sig­nal from each elec­trode is an­a­lyzed with a pre­de­ter­mined re­sponse func­tion up to 50 Hz. The beam po­si­tion res­o­lu­tion of the cur­rent sys­tem is lim­it­ed to about 0.1 mm be­cause of ADC res­o­lu­tion. For the Su­perKEKB pro­ject, we have a plan to up­grade the BPM DAQ sys­tem since the Linac should pro­vide the small­er emit­tance beam. We will re­port on the sys­tem de­scrip­tion of the new DAQ sys­tem and the re­sults of per­for­mance test in de­tail.

  To fa­cil­i­tate front­line nu­cle­ar physics re­search, an ISOL (Iso­tope Sep­a­ra­tor On Line) type Ra­dioac­tive Ion Beam (RIB) fa­cil­i­ty is being con­struct­ed at Vari­able En­er­gy Cy­clotron Cen­tre (VECC), Kolkata. The RIB fa­cil­i­ty at VECC con­sists of var­i­ous sub­sys­tems like ECR Ion source, RFQ, Re­bunch­ers, LINACs etc. that pro­duce and ac­cel­er­ate the en­er­get­ic beam of ra­dioac­tive iso­topes re­quired for dif­fer­ent ex­per­i­ments. The Dis­tribut­ed Data Ac­qui­si­tion and Con­trol Sys­tem (DDACS) is in­tend­ed to mon­i­tor and con­trol large num­ber of pa­ram­e­ters as­so­ci­at­ed with dif­fer­ent sub sys­tems from a cen­tral­ized lo­ca­tion to do the com­plete op­er­a­tion of beam gen­er­a­tion and beam tun­ing in a user friend­ly man­ner. The DDACS has been de­signed based on a 3-lay­er ar­chi­tec­ture name­ly Equip­ment in­ter­face layer, Su­per­vi­so­ry layer and Op­er­a­tor in­ter­face layer. The Equip­ment in­ter­face layer con­sists of dif­fer­ent Equip­ment In­ter­face Mod­ules (EIMs) which are de­signed around ARM pro­ces­sor and con­nect­ed to dif­fer­ent equip­ment through var­i­ous in­ter­faces such as RS-232, RS-485 etc. The Su­per­vi­so­ry layer con­sists of VIA-pro­ces­sor based Em­bed­ded Con­troller (EC) with em­bed­ded XP op­er­at­ing sys­tem. This em­bed­ded con­troller, in­ter­faced with EIMs through fiber optic cable, ac­quires and anal­y­ses the data from dif­fer­ent EIMs. Op­er­a­tor in­ter­face layer con­sists main­ly of PCs/Work­sta­tions work­ing as op­er­a­tor con­soles. The data ac­quired and anal­ysed by the EC can be dis­played at the op­er­a­tor con­sole and the op­er­a­tor can cen­tral­ly su­per­vise and con­trol the whole fa­cil­i­ty.

  The con­trol sys­tem for the Linac Co­her­ent Light Source (LCLS) began as a com­bi­na­tion of new and lega­cy sys­tems. When the LCLS began op­er­at­ing, the bulk of the fa­cil­i­ty was newly con­struct­ed, in­clud­ing a new con­trol sys­tem using the Ex­per­i­men­tal Physics and In­dus­tri­al Con­trol Sys­tem (EPICS) frame­work. The Lin­ear Ac­cel­er­a­tor (LINAC) por­tion of the LCLS was re­pur­posed for use by the LCLS and was con­trolled by the lega­cy sys­tem, which was built near­ly 30 years ago. This sys­tem uses CAMAC, dis­tribut­ed 80386 mi­cro­pro­ces­sors, and a cen­tral Alpha 6600 com­put­er run­ning the VMS op­er­at­ing sys­tem. This lega­cy con­trol sys­tem has been suc­cess­ful­ly up­grad­ed to EPICS dur­ing LCLS pro­duc­tion op­er­a­tions while main­tain­ing the 95% up­time re­quired by the LCLS users. The suc­cess­ful tran­si­tion was made pos­si­ble by thor­ough test­ing in sec­tions of the LINAC which were not in use by the LCLS. Ad­di­tion­al­ly, a sys­tem was im­ple­ment­ed to switch con­trol of a LINAC sec­tion be­tween new and lega­cy con­trol sys­tems in a few min­utes. Using this rapid switch­ing, test­ing could be per­formed dur­ing main­te­nance pe­ri­ods and ac­cel­er­a­tor de­vel­op­ment days. If any prob­lems were en­coun­tered after a sec­tion had been switched to the new con­trol sys­tem, it could be quick­ly switched back.

  The Per­son­nel Safe­ty Sys­tem is based on PILZ PLCs, SIL3 com­pat­i­ble fol­low­ing the norm IEC 61508. It is in­de­pen­dent from other sub­sys­tems and re­lies on a ded­i­cat­ed cer­ti­fi­ca­tion by PILZ first and then by TÜV. The Equip­ment Pro­tec­tion Sys­tem uses B&R hard­ware and com­pris­es more than 50 PLCs and more than 100 dis­tribut­ed I/0 mod­ules in­stalled in­side the tun­nel. The CPUs of the PLCs are in­ter­con­nect­ed by a de­ter­min­is­tic net­work, su­per­vis­ing more than 7000 sig­nals. Each Beam­line has an in­de­pen­dent sys­tem. The fast in­ter­locks use the bidi­rec­tion­al fibers of the MRF tim­ing sys­tem for dis­tribut­ing the in­ter­locks in the mi­crosec­ond range. Events are dis­tribut­ed by fiber op­tics for syn­chro­niz­ing more than 280 el­e­ments.

FERMI@​Elettra is a Free Elec­tron Laser (FEL) based on a 1.5 GeV linac present­ly under com­mis­sion­ing in Tri­este, Italy. Three PLC-based sys­tems com­mu­ni­cat­ing to each other as­sure the pro­tec­tion of ma­chine de­vices and equip­ment. The first is the in­ter­lock sys­tem for the linac ra­diofre­quen­cy plants; the sec­ond is ded­i­cat­ed to the pro­tec­tion of vac­u­um de­vices and mag­nets; the third is in charge of pro­tect­ing var­i­ous ma­chine com­po­nents from ra­di­a­tion dam­age. They all make use of a dis­tribut­ed ar­chi­tec­ture based on field­bus tech­nol­o­gy and com­mu­ni­cate with the con­trol sys­tem via Eth­er­net in­ter­faces and ded­i­cat­ed Tango de­vice servers. A com­plete set of tools in­clud­ing graph­i­cal pan­els, log­ging and archiv­ing sys­tems are used to mon­i­tor the sys­tems from the con­trol room.

Beam-based feed­back con­trol loops are re­quired by the Linac Co­her­ent Light Source (LCLS) pro­gram in order to pro­vide fast, sin­gle-pulse sta­bi­liza­tion of beam pa­ram­e­ters. Eight trans­verse feed­back loops, a 6x6 lon­gi­tu­di­nal feed­back loop, and a loop to main­tain the elec­tron bunch charge were suc­cess­ful­ly com­mis­sioned for the LCLS, and have been main­tain­ing sta­bil­i­ty of the LCLS elec­tron beam at beam rates up to 120Hz. In order to run the feed­back loops at beam rate, the feed­back loops were im­ple­ment­ed in EPICS IOCs with a ded­i­cat­ed eth­er­net mul­ti­cast net­work. This paper will dis­cuss the de­sign, con­fig­u­ra­tion and com­mis­sion­ing of the beam-based Fast Feed­back Sys­tem for LCLS. Top­ics in­clude al­go­rithms for 120Hz feed­back, mul­ti­cast net­work per­for­mance, ac­tu­a­tor and sen­sor per­for­mance for sin­gle-pulse con­trol and sen­sor read­back, and feed­back con­fig­u­ra­tion and run­time con­trol.

FERMI@​Elettra is a new 4th-gen­er­a­tion light source based on a sin­gle pass Free Elec­tron Laser (FEL). In order to en­sure the fea­si­bil­i­ty of the free elec­tron las­ing and the qual­i­ty of the pro­duced pho­ton beam, a high de­gree of sta­bil­i­ty is re­quired for the main pa­ram­e­ters of the elec­tron beam. For this rea­son a flex­i­ble re­al-time feed­back frame­work in­te­grat­ed in the con­trol sys­tem has been de­vel­oped. The first im­ple­ment­ed bunch-by-bunch feed­back loop con­trols the beam tra­jec­to­ry. The mea­sure­ments of the beam po­si­tion and the cor­rec­tor mag­net set­tings are syn­chro­nized to the 50 Hz linac rep­e­ti­tion rate by means of the re­al-time frame­work. The feed­back sys­tem im­ple­men­ta­tion, the con­trol al­go­rithms and pre­lim­i­nary close loop re­sults are pre­sent­ed.

  The China Spal­la­tion Neu­tron Source (CSNS) is plan­ning to start con­struc­tion in 2011 in China. The CSNS con­trols sys­tem will use EPICS as de­vel­op­ment plat­form. The scope of the con­trols sys­tem cov­ers thou­sands of de­vices lo­cat­ed in Linac, RCS and two trans­fer lines. The in­ter­face from the con­trol sys­tem to the equip­ment will be through VME Power PC pro­ces­sors and em­bed­ded PLC as well as em­bed­ded IPC. The high level ap­pli­ca­tions will choose XAL core and Eclipse plat­form. Or­a­cle database is used to save his­tor­i­cal data. This paper in­tro­duces con­trols pre­lim­i­nary de­sign and progress. Some key tech­nolo­gies, pro­to­types,sched­ule and per­son­nel plan are also dis­cussed.
