The Korea multi-pur­pose ac­cel­er­a­tor com­plex (KOMAC) has two beam ex­trac­tion points at 20 and 100 MeV for pro­ton beam uti­liza­tion. High avail­abil­ity should be achieved through high sys­tem re­li­a­bil­ity and short main­te­nance times to pre­vent and mit­i­gate dam­age. A ma­chine pro­tec­tion sys­tem is es­sen­tial for avoid­ing dam­age lead­ing to long main­te­nance times. KOMAC MPS that was de­vel­oped using ana­log cir­cuit in­ter­lock box has its limit to cover in­creas­ing in­ter­lock sig­nals and mod­ify in­ter­lock logic. The dis­ad­van­tage has been solved with dig­i­tal-based sys­tem for more ef­fi­cient logic mod­i­fi­ca­tion and in­ter­lock ex­ten­sion. The MPS is con­fig­ured re­motely using the EPICS-based ap­pli­ca­tion. In this paper, we pre­sent KOMAC ma­chine pro­tec­tion ar­chi­tec­ture and per­for­mance re­sults of the new ma­chine pro­tec­tion sys­tem.

  SKA (Square Kilo­me­ter Array) is a pro­ject aimed to build a very large ra­dio-tele­scope, com­posed by thou­sands of an­ten­nae and re­lated sup­port sys­tems. The over­all or­ches­tra­tion is per­formed by the Tele­scope Man­ager (TM), a suite of soft­ware ap­pli­ca­tions. In order to en­sure the proper and un­in­ter­rupted op­er­a­tion of TM, a local mon­i­tor­ing and con­trol sys­tem is de­vel­oped, called TM Ser­vices. Fault Man­age­ment (FM) is one of these ser­vices, and is com­posed by processes and in­fra­struc­ture as­so­ci­ated with de­tect­ing, di­ag­nos­ing and fix­ing faults, and fi­nally re­turn­ing to nor­mal op­er­a­tions. The aim of the study, in­tro­duc­ing ar­ti­fi­cial in­tel­li­gence al­go­rithms dur­ing the de­tec­tion phase, is to build a pre­dic­tive model, based on the his­tory and sta­tis­tics of the sys­tem, in order to per­form trend analy­sis and fail­ure pre­dic­tion. Based on mon­i­tor­ing data and health sta­tus de­tected by the soft­ware sys­tem mon­i­tor and on log files gath­ered by the ELK (Elas­tic­search, Logstash, and Kibana) server, the pre­dic­tive model en­sures that the sys­tem is op­er­at­ing within its nor­mal op­er­at­ing pa­ra­me­ters and takes cor­rec­tive ac­tions in case of fail­ure.

  The ISOLDE fa­cil­ity at CERN re­quires a wide va­ri­ety of soft­ware ap­pli­ca­tions to en­sure max­i­mum pro­duc­tiv­ity. It will be fur­ther en­forced by two new and in­no­v­a­tive ap­pli­ca­tions; Au­to­matic Save After set uP (ASAP) and Fast Beam In­ves­ti­ga­tion (FBI). ASAP saves cru­cial time for the en­gi­neers in charge (EIC) dur­ing the physics cam­paign. It au­tom­a­tizes and stan­dard­izes a repet­i­tive process. In ad­di­tion, for each new set up, the EIC is re­quired to doc­u­ment the set­tings of all im­por­tant el­e­ments be­fore de­liv­er­ing beam to the users. FBI will be serv­ing two dif­fer­ent needs. First, it will be used as a beam trace­abil­ity tool. The set­tings of every el­e­ment of ISOLDE that could ob­struct, stop or af­fect the beam will be tracked by the ap­pli­ca­tion. This will allow to un­der­stand bet­ter the pres­ence of ra­dioac­tive con­t­a­m­i­nants after each ex­per­i­ment at every pos­si­ble point in the fa­cil­ity. The sec­ond func­tion­al­ity will allow real time mon­i­tor­ing of the ma­chine sta­tus dur­ing a physics run. FBI will be the most ef­fi­cient way to vi­su­al­ize the sta­tus of the ma­chine and find the rea­son that pre­vents the beam from ar­riv­ing to the ex­per­i­men­tal sta­tion.

  The HIE-ISOLDE Linac (High In­ten­sity and En­ergy) is a re­cent up­grade to the ISOLDE fa­cil­ity of CERN, in­creas­ing the max­i­mum beam en­ergy and pro­vid­ing means to ex­plore more sci­en­tific op­por­tu­ni­ties. The main soft­ware tools re­quired to set up the new su­per­con­duct­ing post-ac­cel­er­a­tor and to char­ac­terise the beam pro­vided to the ex­per­i­men­tal sta­tions will be pre­sented in this paper. Em­pha­sis will be given to the suite of ap­pli­ca­tions to con­trol all beam in­stru­men­ta­tion equip­ment which are more com­plex com­pared to the ones in the low en­ergy part of ISOLDE. A va­ri­ety of de­vices are used (Fara­day cups, col­li­ma­tors, scan­ning slits, strip­ing foils and sil­i­con de­tec­tors). Each serves its own pur­pose and pro­vides dif­fer­ent in­for­ma­tion con­cern­ing the beam char­ac­ter­is­tics. Every group of de­vices re­quired a spe­cific ap­proach to be pro­grammed.

  CERN MEDICIS is a re­search fa­cil­ity that will make ra­dioiso­topes for med­ical ap­pli­ca­tions using the pri­mary pro­ton beam at ISOLDE. It will start op­er­at­ing later in 2017. The high level ap­pli­ca­tion for the new beam line is re­spon­si­ble for the con­trol of var­i­ous equip­ment, such as power sup­plies, Fara­day cups and scan­ners, as well as the mon­i­tor­ing of en­vi­ron­men­tal pa­ra­me­ters such as the vac­uum level. It is char­ac­ter­ized by a sin­gle user friendly in­ter­face to fa­cil­i­tate the op­er­a­tors tasks. In this paper we pro­vide ar­gu­ments for the cho­sen so­lu­tion and give the lat­est up­date on the sta­tus of the pro­ject.

The phase ref­er­ence sig­nal re­li­a­bil­ity is of ut­most im­por­tance for con­tin­u­ous op­er­a­tion of the Eu­ro­pean XFEL ma­chine. Since even very short in­ter­rup­tion or glitch in the ref­er­ence sig­nal might break the pre­cise syn­chro­ni­sa­tion be­tween sub­sys­tems, it is de­sir­able to min­i­mize prob­a­bil­ity of such events. While mas­ter os­cil­la­tors often have a hot-spare to speed-up re­cov­ery after a fail­ure, whether switched man­u­ally or elec­tron­i­cally, it does not save from time-con­sum­ing re­syn­chro­ni­sa­tion. Our ex­pe­ri­ence from test­ing and com­mis­sion­ing E-XFEL 1.3 GHz Mas­ter Os­cil­la­tor (MO) shows that a strug­gle to achieve de­mand­ing phase-noise re­quire­ments might neg­a­tively im­pact re­li­a­bil­ity of the sys­tem. In this paper we pre­sent an ap­proach which al­lows for quick switch­ing be­tween in­de­pen­dent ref­er­ence gen­er­a­tion chan­nels while main­tain­ing con­ti­nu­ity of the out­put sig­nal. This is a first step to­wards au­tonomous re­dun­dancy so­lu­tion for the E-XFEL MO which will main­tain con­tin­u­ous ref­er­ence sig­nal even in case of a fail­ure of one of the gen­er­a­tion chan­nels.

  Ac­cess to the in­ter­locked zones of the CERN ac­cel­er­a­tor com­plex is al­lowed only for per­son­nel wear­ing stan­dard per­sonal pro­tec­tive equip­ment. This equip­ment is com­ple­mented by spe­cialised per­sonal pro­tec­tive de­vices in case of spe­cific haz­ards re­lated to the rem­nant ra­di­a­tion or the pres­ence of cryo­genic flu­ids. These com­plex de­vices mon­i­tor the en­vi­ron­ment in the vicin­ity of the user and warn the user of the pres­ence of haz­ards such as ra­di­a­tion or oxy­gen de­fi­ciency. The use of the de­vices is oblig­a­tory, but cur­rently only en­forced by pro­ce­dures. In order to im­prove the safety of the per­son­nel it has been pro­posed to ver­ify that users are car­ry­ing their de­vices switched on when en­ter­ing. This paper de­scribes the de­vel­op­ment of a spe­cialised multi-pro­to­col ter­mi­nal, based on Texas In­stru­ments dig­i­tal sig­nal proces­sor and in­te­grated in the per­son­nel pro­tec­tion sys­tem. The de­vice per­forms local checks of the pres­ence and sta­tus of op­er­a­tional dosime­ter prior to al­low­ing ac­cess to the in­ter­locked zones. The re­sults of the first tests in the Pro­ton Syn­chro­tron ac­cel­er­a­tor com­plex will be pre­sented.
