The Dae­jeon ion ac­cel­er­a­tor com­plex (DIAC) is being con­structed at Korea Atomic En­ergy Re­search In­sti­tute (KAERI) in order to ful­fill an in­creas­ing de­mand for heavy ion beam fa­cil­i­ties for var­i­ous pur­poses in­clud­ing ma­te­r­ial study and bi­o­log­i­cal re­search. Based on de­vices of the Tokai ra­dioac­tive ion ac­cel­er­a­tor com­plex re­ceived from high en­ergy ac­cel­er­a­tor re­search or­ga­ni­za­tion (KEK), Japan, the ded­i­cated ac­cel­er­a­tors in the DIAC are de­signed to pro­duce sta­ble heavy ion beams with en­er­gies up to 1 MeV/u. To date, (1) as­sem­bly of the elec­tron cy­clotron res­o­nance (ECR) ion source and linacs de­liv­ered in pieces from the KEK (2) in­stal­la­tion of the power sup­ply, coolant cir­cu­la­tion sys­tem, and vac­uum pump sys­tem, (3) op­er­a­tion test of the ECR ion source, (4) full-power tests of the in­ter­dig­i­tal H-type (IH) and ra­dio-fre­quency quadru­pole (RFQ) linacs, (5) con­struc­tion of a ra­di­a­tion shielded walls for the DIAC, (6) tests of tuners in the RFQ, IH, and re­buncher, and (7) re­or­ga­ni­za­tion of the in­te­grated con­trol sys­tem have been com­pleted. In the pre­sen­ta­tion, cur­rent sta­tus, plans, and test re­sults for the DIAC con­struc­tion will be pre­sented and dis­cussed in de­tail.

  In the IFMIF EVEDA pro­ject*, INFN-LNL Lab­o­ra­tory has been in­volved in the de­sign and con­struc­tion of a nor­mal con­duct­ing Radio Fre­quency Quadru­pole (RFQ) used to bunch and ac­cel­er­ate a 130 mA steady beam to 5 MeV. The EPICS based con­trol sys­tem** has been en­tirely de­vel­oped in house using dif­fer­ent hard­ware so­lu­tions: PLC for tasks where se­cu­rity is the most crit­i­cal fea­ture, VME sys­tem where the ac­qui­si­tion speed rate is cru­cial, com­mon hard­ware when only in­te­gra­tion is re­quired with­out any par­tic­u­lar fea­ture in terms of se­cu­rity. In­te­gra­tion of PLCs into EPICS en­vi­ron­ment was orig­i­nally ac­com­plished through OPC DA server*** hosted by a Win­dows em­bed­ded in­dus­trial PC. Due to the is­sues an­a­lyzed in in­jec­tor LCS, LNL pro­posed to mi­grate to the usage of EPICS Di­rect Dri­ver so­lu­tion based on s7plc****. The dri­ver it­self is suit­able for di­rect com­mu­ni­ca­tion be­tween EPICS and PLCs, but it doesn't take care of data up­date and syn­chro­niza­tion in case of com­mu­ni­ca­tion fail­ure. As con­se­quence LNL team de­signed a ded­i­cated method based on state ma­chine to man­age and ver­ify data in­tegrity be­tween the two en­vi­ron­ments, also in case of con­nec­tion lost or fail­ure.

  The RFQ ap­pa­ra­tus Local Con­trol Sys­tem built for IFMIF EVEDA Pro­ject* has been de­signed and re­al­ized for being both a stand­alone ar­chi­tec­ture and part of a more com­plex con­trol sys­tem com­posed by dif­fer­ent sub-sys­tems. This ap­proach let RFQ's en­gi­neers and sci­en­tists have a de­gree of free­dom dur­ing power tests in Leg­naro and dur­ing the RFQ in­te­gra­tion in IFMIF EVEDA fa­cil­ity in Rokkasho. In this paper we will de­scribe the dif­fer­ent as­pects ob­served when the LCS was con­verted from the stand­alone con­fig­u­ra­tion to the final in­te­grated one.
