  Spi­ral2 whose con­struc­tion phys­i­cal­ly start­ed at the be­gin­ning of this year at Ganil (Caen, France) will be a new Ra­dioac­tive Ion Beams fa­cil­i­ty to ex­tend sci­en­tif­ic knowl­edge in nu­cle­ar physics, as­tro­physics and in­ter­dis­ci­plinary re­search­es. The pro­ject con­sists of a high in­ten­si­ty mul­ti-ion ac­cel­er­a­tor driv­er de­liv­er­ing beams to a high power pro­duc­tion sys­tem to gen­er­ate the Ra­dioac­tive Ion Beams being then post-ac­cel­er­at­ed and used with­in the ex­ist­ing Ganil com­plex. Re­sult­ing from the col­lab­o­ra­tion be­tween sev­er­al lab­o­ra­to­ries, Epics has been adopt­ed as the stan­dard frame­work for the con­trol com­mand sys­tem. At the lower level, pieces of equip­ment are han­dled through VME/Vx­Works chas­sis or di­rect­ly in­ter­faced using the Mod­bus/TCP pro­to­col; also, Siemens pro­grammable logic con­trollers are tight­ly cou­pled to the con­trol sys­tem, being in charge of spe­cif­ic de­vices or hard­ware safe­ty sys­tems. The graph­i­cal user in­ter­face layer in­te­grates both some stan­dard Epics client tools (EDM, CSS under eval­u­a­tion, etc …) and spe­cif­ic high level ap­pli­ca­tions writ­ten in Java, also de­riv­ing de­vel­op­ments from the Xal frame­work. Re­la­tion­al databas­es are in­volved into the con­trol sys­tem for equip­ment con­fig­u­ra­tion (fore­seen), ma­chine rep­re­sen­ta­tion and con­fig­u­ra­tion, CSS archivers (under eval­u­a­tion) and Irmis (main­ly for pro­cess vari­able de­scrip­tion). The first com­po­nents of the Spi­ral2 con­trol sys­tem are now used in op­er­a­tion with­in the con­text of the ion and deuteron sources test plat­forms. The paper also de­scribes how soft­ware de­vel­op­ment and shar­ing is man­aged with­in the col­lab­o­ra­tion.

  The EPICS frame­work was cho­sen for the Spi­ral2 pro­ject con­trol sys­tem [1] in 2007. Four in­sti­tutes are in­volved in the com­mand con­trol: Ganil (Caen), IPHC (Stras­bourg) and IRFU (Saclay) and LPSC (Greno­ble), the IRFU in­sti­tute being in charge of the In­jec­tor con­trols. This in­jec­tor in­cludes two ECR sources (one for deuterons and one for A/q= 3 ions) with their as­so­ci­at­ed low-en­er­gy beam trans­port lines (LEBTs). The deuteron source is in­stalled at Saclay and the A/q=3 ion source at Greno­ble. Both lines will merge be­fore in­ject­ing beam in a RFQ cav­i­ty for pre ac­cel­er­a­tion. This paper pre­sents the con­trol sys­tem for both in­jec­tor beam­lines with their di­ag­nos­tics (Fara­day cups, ACCT/DCCT, pro­fil­ers, emit­tanceme­ters) and slits. This con­trol re­lies on COTS VME boards and an EPICS soft­ware plat­form. Mod­bus/TCP pro­to­col is also used with COTS de­vices like power sup­plies and Siemens PLCs. The In­jec­tor graph­i­cal user in­ter­face is based on Edm while the port to CSS BOY is under eval­u­a­tion; also high level ap­pli­ca­tions are de­vel­oped in Java. This paper also em­pha­sizes the EPICS de­vel­op­ment for new in­dus­tri­al VME boards ADAS ICV108/178 with a sam­pling rate rang­ing from 100 K Sam­ples/s to 1.2 M Sam­ples/s. This new soft­ware is used for the beam in­ten­si­ty mea­sure­ment by di­ag­nos­tics and the ac­qui­si­tion of sources.

  The SPI­RAL2 lin­ear ac­cel­er­a­tor will pro­duce en­tire­ly new par­ti­cle beams en­abling ex­plo­ration of the bound­aries of mat­ter. Cou­pled with the ex­ist­ing GANIL ma­chine this new fa­cil­i­ty will pro­duce light and heavy ex­ot­ic nu­clei at ex­treme­ly high in­ten­si­ties. The field de­ploy­ment of the Con­trol Sys­tem re­lies on Linux PCs and servers, VME Vx­Works crates and Siemens PLCs; equip­ment will be ad­dressed ei­ther di­rect­ly or using a Mod­bus/TCP field bus net­work. Sev­er­al lab­o­ra­to­ries are in­volved in the soft­ware de­vel­op­ment of the con­trol sys­tem. In order to im­prove ef­fi­cien­cy of the col­lab­o­ra­tion, spe­cial care is taken of the soft­ware or­ga­ni­za­tion. Dur­ing the de­vel­op­ment phase, in a con­text of tough bud­get and time con­straints, this re­al­ly makes sense, but also for the ex­ploita­tion of the new ma­chine, it helps us to de­sign a con­trol sys­tem that will re­quire as lit­tle ef­fort as pos­si­ble for main­te­nance and evo­lu­tion. The major con­cepts of this or­ga­ni­za­tion are the choice of EPICS, the def­i­ni­tion of an EPICS di­rec­to­ry tree spe­cif­ic to SPI­RAL2, called "top­SP2": this is our ref­er­ence work area for de­vel­op­ment, in­te­gra­tion and ex­ploita­tion, and the use of ver­sion con­trol sys­tem (SVN) to store and share our de­vel­op­ments in­de­pen­dent­ly of the mul­ti-site di­men­sion of the pro­ject. The next con­cept is the def­i­ni­tion of a "stan­dard­ized in­ter­face" be­tween high level ap­pli­ca­tions pro­grammed in Java and EPICS databas­es run­ning in IOCs. This paper re­lates the ra­tio­nale and ob­jec­tives of this in­ter­face and also its de­vel­op­ment cycle from spec­i­fi­ca­tion using UML di­a­grams to test­ing on the ac­tu­al equip­ment.
