  In the IFMIF EVEDA pro­ject, nor­mal con­duct­ing Radio Fre­quency Quadru­pole (RFQ) is used to bunch and ac­cel­er­ate a 130 mA steady beam to 5 MeV. RFQ cav­ity is di­vided into three struc­tures, named su­per-mod­ules. Each su­per-mod­ule is di­vided into 6 mod­ules for a total of 18 mod­ules for the over­all struc­ture. The final three mod­ules have to be tested at high power to test and val­i­date the most crit­i­cal RF com­po­nents of RFQ cav­ity and, on the other hand, to test per­for­mances of the main an­cil­lar­ies that will be used for IFMIF EVEDA pro­ject (vac­uum man­i­fold sys­tem, tun­ing sys­tem and con­trol sys­tem). The choice of the last three mod­ules is due to the fact that they will op­er­ate in the most de­mand­ing con­di­tions in terms of power den­sity (100 kW/m) and sur­face elec­tric field (1.8*Ekp). The Ex­per­i­men­tal Physics and In­dus­trial Con­trol Sys­tem (EPICS) en­vi­ron­ment [1] pro­vides the frame­work for mon­i­tor­ing any equip­ment con­nected to it. This paper re­ports the usage of this frame­work to the RFQ power tests at Leg­naro Na­tional Lab­o­ra­to­ries [2,3,4].

  The SXFEL (Soft X-ray Free Elec­tron Laser) and DCLS (Dalian Co­her­ence Light Source) have been under con-struc­tions since 2015. To sat­isfy the huge de­mands of dig­i­tal beam po­si­tion mon­i­tor proces­sor, we batch pro-duced over 200 sets of DBPM proces­sor. This paper de-scribes a high au­to­matic test plat­form based on MAT­LAB and SCPI, used for the de­vice ac­cep­tance test and per­for­mance eval­u­a­tion. The sim­u­la­tion beam sig-nals gen­er­ated by the Ag­i­lent sig­nal source MXG N5181A, con­nected to a 4-way power split­ter. The net­work con­trol sys­tem based on the ar­chi­tec­ture of the client and server mode, in­te­grated in­stru­ments test com­mands and ex­per-imen­tal data trans­ferred via a Mer­cury router. Using EP-ICS LabCA re­al­ized the data ac­qui­si­tion chan­nel ac­cess in­ter­face. The plat­form has been suc­cess­fully used for the Dalian Co­her­ent Light Source (DCLS) de­vices ac­cep­tance test­ing, the noise level, crosstalk be­tween chan­nels, am­pli-tude fre­quency re­sponse and SNR test re­ports au­to­matic gen­er­a­tion under test.

  This paper re­ports the progress of the con­trol sys­tem for IPM 10 MeV ac­cel­er­a­tor. As an elec­tron linac, it con­sists of beam in­jec­tion ac­cel­er­a­tion tube, radio fre­quency pro­duc­tion and trans­mis­sion, tar­get, di­ag­nos­tics and con­trol and safety. In sup­port of this source, an EPICS-based in­te­grated con­trol sys­tem has been de­signed and being im­ple­mented from scratch to pro­vide ac­cess to the crit­i­cal con­trol points and con­tin­ues to grow to sim­plify op­er­a­tion of the sys­tem. In ad­di­tion to a PLC-based ma­chine pro­tec­tion com­po­nent and IO in­ter­face, a CSS-based suite of con­trol GUI mon­i­tors sys­tems in­clud­ing Mod­u­la­tor and RF, Vac­uum, Mag­nets, and elec­tron gun. An overview of this sys­tem is pre­sented in this ar­ti­cle.

  The Tai­wan Light Source (TLS) is a third gen­er­a­tion of syn­chro­tron light source, and it has been op­er­ated since 1993. The TLS con­trol sys­tem is a pro­pri­etary de­sign. It was per­formed minor up­grade sev­eral times to avoid ob­so­lete of some sys­tem com­po­nents and keep up-to-date dur­ing last two decades. The con­trol sys­tem of BTS (Booster-to-Stor­age ring) trans­port line in­cludes con­trol in­ter­faces of power sup­plies, screen mon­i­tors, vac­uum and tem­per­a­ture. The cPCI (Com­pact­PCI) based EPICS IOC (Input Out­put Con­troller) has been adopted for re­new­ing TLS BTS con­trol sys­tem to re­place the ex­isted VME based ILC (In­tel­li­gent Local Con­troller) to be as an easy-to-main­tain con­trol en­vi­ron­ment. More­over, each TLS con­trol con­sole sup­ports not only the ex­ist­ing con­trol soft­ware in­ter­faces, but also the newly de­vel­oped EPICS graph­i­cal user in­ter­faces. Up­graded TLS BTS con­trol sys­tem had been suc­cess­fully com­mis­sion­ing in Feb­ru­ary 2017. Com­pare new sys­tem with old sys­tem, new sys­tem pro­vides more func­tion­al­ity, fast re­sponse, and highly re­li­a­bil­ity. The ef­forts are sum­ma­rized at this paper.

  The pre­sen­ta­tion pro­vides an overview of the ChimeraTK frame­work. The pro­ject started from a de­mand for soft­ware li­braries that pro­vide con­ve­nient ac­cess to PCIE bus based cards on the Mi­croTCA.4 plat­form. Pre­vi­ously called MT­CA4U, ChimeraTK is evolv­ing to­wards a set of frame­works and tools that en­able users to build up con­trol ap­pli­ca­tions, while ab­stract­ing away specifics of the un­der­ly­ing sys­tem. Ini­tially, the focus of the pro­ject was the De­viceAc­cess C++ li­brary and its bind­ings for Mat­lab and Python, along with a Qt based client that used De­viceAc­cess under the hood. How­ever, ChimeraTK has ex­panded to in­clude more tools like the Con­trol­Sys­temAdapter, Vir­tu­al­Lab and Ap­pli­ca­tion­Core. The Con­trol­Sys­temAdapter frame­work fo­cuses on tools that en­able ap­pli­ca­tion code to be writ­ten in a mid­dle ware ag­nos­tic man­ner. Vir­tu­al­Lab fo­cuses on fa­cil­i­tat­ing test­ing of ap­pli­ca­tion code and pro­vid­ing func­tional mocks. The Ap­pli­ca­tion­Core li­brary aims at uni­fy­ing ap­pli­ca­tion in­ter­faces to other tools in the toolkit and im­prov­ing ab­strac­tion. We pre­sent an up­date on im­prove­ments to the pro­ject and dis­cuss mo­ti­va­tions and ap­pli­ca­tions for these new set of tools in­tro­duced into the toolkit.

  The Cooler Syn­chro­tron (COSY) at Forschungszen­trum Jülich is cur­rently car­ry­ing out the prepa­ra­tion for a di­rect mea­sure­ment of the elec­tric Di­pole Mo­ment (EDM) of the deuteron using an RF Wien fil­ter*,**. In a mag­netic stor­age ring with the spin vec­tor aligned along the di­rec­tion of mo­tion, the EDM man­i­fests in a buildup of the ver­ti­cal spin com­po­nent. Be­sides this sig­nal, ra­dial mag­netic fields due to a dis­tor­tion of the ver­ti­cal closed orbit can pro­duce a sim­i­lar sig­nal. This sig­nal is a sys­tem­atic limit of the pro­posed mea­sure­ment pro­ce­dure. Based on sim­u­la­tion stud­ies***, a ver­ti­cal closed orbit dis­tor­tion with a RMS smaller than 0.1 mm is re­quired to achieve a sen­si­tiv­ity of 10-19 e.​cm or bet­ter. In order to ac­com­plish this chal­leng­ing goal, a slow orbit feed­back sys­tem was pro­posed and re­cently com­mis­sioned at COSY. The de­sign and com­mis­sion­ing re­sults will be pre­sented, and the fu­ture plan will also be dis­cussed.

  The in­ter­lock sys­tem is an es­sen­tial com­po­nent for an ac­cel­er­a­tor fa­cil­ity. A con­fig­urable soft­ware in­ter­lock sys­tem(SIS) is de­signed for Hefei Light Source II (HLS-II), which com­ple­ments the hard­ware in­ter­lock sys­tem to en­sure equip­ment and op­er­a­tors' safety. The sys­tem is de­vel­oped using Python under the EPICS frame­work with the method of sep­a­rat­ing the con­fig­u­ra­tion file from the in­ter­lock pro­gram. The in­ter­lock logic is com­pletely de­ter­mined by the con­fig­u­ra­tion file and its nested tree struc­ture is easy to ex­pand. The test re­sults in­di­cate that the new soft­ware in­ter­lock sys­tem is re­li­able, flex­i­ble and con­ve­nient to op­er­ate. This paper will de­scribe the de­sign and the con­struc­tion of HLS-II SIS.

  FREIA (Fa­cil­ity for RE­search and In­stru­men­ta­tion for Ac­cel­er­a­tor de­vel­op­ment) Lab­o­ra­tory at Up­p­sala Uni­ver­sity, Swe­den, is a new fa­cil­ity, in­au­gu­rated 2013. Ini­tially FREIA is test­ing and de­vel­op­ing su­per­con­duct­ing ac­cel­er­at­ing cav­i­ties and high power RF sources in col­lab­o­ra­tion with the Eu­ro­pean Spal­la­tion Source (ESS). Later pro­jects in­clude test­ing of su­per­con­duct­ing cav­i­ties and mag­nets for the high lu­mi­nos­ity LHC. The high level con­trol, alarm sys­tem and archiv­ing is im­ple­mented in EPICS. Presently this in­cludes a he­lium liq­ue­fac­tion plant, a hor­i­zon­tal test cryo­stat, two high power RF am­pli­fiers, a low level RF sys­tem, en­vi­ron­ment mon­i­tor­ing and safety sys­tems. Some at­ten­tion will be given to in­te­gra­tion of com­mer­cially ac­quired sys­tems as well as the safety sys­tem, in­ter­locks and ra­di­a­tion mon­i­tor­ing. The im­ple­men­ta­tion of the EPICS en­vi­ron­ment fol­lows closely that of ESS and thus can pro­vide a test bench for de­vel­op­ments at ESS.

  The time syn­chro­niza­tion for multi CPU sys­tem is al­ways a prob­lem to be wor­ried. The con­trol sys­tem of ac­cel­er­a­tor is no ex­cep­tion since it con­sists of a lot of CPUs lo­cated among large area dis­tantly. The prob­lem ap­pears con­spic­u­ously when the beam is aborted. Usu­ally, sev­eral hard­ware show abort sig­nals in one beam abort event. How­ever it is dif­fi­cult to know which is the source of beam abort and which is­sues an abort sig­nal under the in­flu­ence of orig­i­nal fail­ure. We in­tro­duce the time syn­chro­niza­tion sys­tem of the Su­perKEKB col­lider which choose EPICS as the con­trol soft­ware. The sys­tem uti­lize Event Tim­ing Sys­tem and syn­chro­nizes the EPICS gen­eral time for I/O con­trollers lo­cated dis­tantly. The ac­cu­racy of syn­chro­niza­tion is around 10ns. It is the ex­cel­lent per­for­mance in terms of syn­chro­niza­tion of CPU time. The all abort chan­nels of Su­perKEKB are syn­chro­nized their is­sued time. Be­sides they syn­chro­nize with also the in­jec­tor linac which is op­er­ated with the dif­fer­ent con­trol sys­tem in dif­fer­ent net­work.

  This paper pre­sents a novel archiv­ing and re­triev­ing soft­ware de­signed for BEPC-II and other par­ti­cle ac­cel­er­a­tors. At BEPC-II, real-time data are stored as index files recorded by tra­di­tional EPICS Chan­nel Archiver. Never-the­less, index files are not suit­able for long-term main­te­nance and dif­fi­cult for data analy­sis. The NoSQL data­base Mon­goDB is used for this new sys­tem due to aging tech­nolo­gies, so as to pro­mote the data stor­age re­li­a­bil­ity, us­abil­ity, and pos­si­ble fu­ture ad­vanced data analy­sis. A cross-plat­form UI (User In­ter­face) has also been de­vel­oped to make it quicker and eas­ier to ac­cess the data­base. The writ­ing and query per­for­mance are tested for this soft­ware.

  At ESS, thou­sands of de­vices will be used to con­trol both the ma­chine and end-sta­tion in­stru­ments. To en­able on­go­ing de­vel­op­ment when ac­cess to these de­vices is not pos­si­ble (for what­ever the rea­son), Kameleon was im­ple­mented. It is a be­hav­ior-rich, non-mem­o­ry­less and time-aware generic sim­u­la­tor that han­dles clients through a TCP/IP con­nec­tion. An in­stance of this client is an EPICS IOC or a Tango De­vice Server. Kameleon con­sumes a user-de­fined file that de­scribes the com­mands re­ceived from a client and, op­tion­ally, the re­ac­tion to these through sta­tuses sent back to the client. Key fea­tures are: 1) Ubiq­ui­tous (runs in dis­parate plat­forms such as Win­dows and Linux). 2) Be­hav­ior-rich (pre­de­fined be­hav­iors as well as user-de­fined). 3) Non-mem­o­ry­less (the state of the sim­u­la­tion can be pre­served be­tween events and/or elapsed time). 4) Time-aware (sta­tuses can be sent to the client ei­ther event-based or time-based). 5) Flex­i­ble (com­mands and sta­tuses are de­scribed in a sim­ple user-de­fined file - noth­ing is hard-coded in Kameleon). Kameleon will be used in a myr­iad of sce­nar­ios at ESS such as de­vel­op­ment of EPICS de­vices sup­port, IOCs, OPI screens, test­ing of IOCs and alarm work­flows.

  The Eu­ro­pean Spal­la­tion Source (ESS) is a re­search fa­cil­ity being built in Lund (Swe­den) that will pro­duce neu­trons by the spal­la­tion process. It uses the Mi­cro-Re­search Fin­land (MRF) Tim­ing Sys­tem, which pro­vides a com­plete event-based tim­ing dis­tri­b­u­tion sys­tem. The tim­ing sig­nal gen­er­a­tion con­sists of a basic topol­ogy: an Event Gen­er­a­tor (EVG), an op­ti­cal dis­tri­b­u­tion layer (fan-out mod­ules) and an array of Event Re­ceivers (EVRs). The tim­ing sys­tem will pro­vide clock syn­chro­niza­tion and tim­ing ser­vices to de­vices with real time re­quire­ments. Its main pur­poses are event gen­er­a­tion and dis­tri­b­u­tion, time stamp­ing and syn­chro­nous data trans­mis­sion. The event clock fre­quency will be 88.0525 MHz, di­vided down from the bunch fre­quency of 352.21 MHz. An in­te­ger num­ber of ticks of this clock will de­fine the beam macropulse full length, around 2.86 ms, with a rep­e­ti­tion rate of 14 Hz. ESS will be the first fa­cil­ity to de­ploy large amounts of uTCA EVRs, and is plan­ning to take ad­van­tage of the fea­tures pro­vided by the uTCA stan­dard, like trig­ger and clock dis­tri­b­u­tion over the back­plane. These EVRs are al­ready being de­ployed in some sys­tems and test stands.

  TPS Linac has been pro­vid­ing with elec­tron beams which con­form to the spec­i­fi­ca­tions to the re­quire­ment since 2014. Firstly elec­trons are ex­tracted from elec­tron gun (e-gun), and they are ac­cel­er­ated and gained en­ergy from 90 keV to 150 MeV in three lin­ear ac­cel­er­at­ing sec­tions. Then elec­tron beams are suc­cess­fully in­jected to the booster ring via Linac to Booster (LTB) trans­port line. Pro­vid­ing a sta­ble and re­li­able op­er­at­ing sys­tem is next pri­or­ity ob­jec­tive and so a tem­per­a­ture mon­i­tor­ing sys­tem is es­tab­lished. This tem­per­a­ture mon­i­tor­ing sys­tem is used to mon­i­tor the tem­per­a­tures for each Linac sub-sys­tem and its sur­round­ing en­vi­ron­ment. By using this tem­per­a­ture mon­i­tor­ing sys­tem, it helps to un­der­stand the re­la­tion be­tween beam en­ergy and work­ing tem­per­a­ture for each sub-sys­tem, when Linac is under nor­mal op­er­a­tion. This re­port will de­tail the tem­per­a­ture mon­i­tor­ing com­po­nents, in­clud­ing ther­mal­cou­ples, PLC ther­mal mod­ules, PLC pro­gram­ming and graphic user in­ter­face (GUI). By in­te­grat­ing with EPICS, this mon­i­tor­ing sys­tem is be­com­ing a com­plete so­lu­tion for en­sur­ing any pos­si­ble in­flu­ence due to ther­mal ef­fects.
