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.
