Lin­ear IFMIF* Pro­to­type Ac­cel­er­a­tor (LIPAc), Rokkasho, Japan, com­prises a suc­ces­sion of de­vices and sys­tems that ac­cel­er­ate a deuteron beam up to 9 MeV with a cur­rent of 125 mA, gen­er­at­ing a power of 1.125 MW, and trans­port it up to a beam dump. The beam power be­comes crit­i­cal from the point of view of losses; even tiny losses must be avoided. This fact, and the com­plex­ity of the ac­cel­er­a­tor op­er­a­tion, re­quires a co­her­ent strat­egy when de­sign­ing, com­mis­sion­ing and op­ti­miz­ing the ac­cel­er­a­tor con­trol sys­tem, specif­i­cally fo­cused in the con­trol sys­tems of the Medium En­ergy Beam Trans­port (MEBT) and the Di­ag­nos­tic Plate (DP, a mov­able set of di­ag­nos­tics). Both sys­tems are es­sen­tial to val­i­date the per­for­mance of the ac­cel­er­a­tor and par­tic­u­larly the ion source, Radio Fre­quency (RF) and Radio Fre­quency Quadru­pole (RFQ) sys­tems. This con­tri­bu­tion will de­scribe the re­cent ad­vances in the con­trol ar­chi­tec­tures and the EPICS based de­vel­op­ments achieved in MEBT for the mo­tion con­trol of bunch­ers and scrap­ers, con­trol of the power sup­plies in quadrupoles and steer­ers, and re­frig­er­a­tion and vac­uum. Be­sides, con­trol of flu­o­res­cence pro­file mon­i­tors (FPMs) in the D-Plate is dis­played.
*IFMIF, the International Fusion Materials Irradiation Facility, is an accelerator-based neutron source that will use Li (d, xn) reactions to generate a flux of neutrons with a broad peak at 14 MeV.
