  For many years our Institute CEA IRFU has had a sound experience in VME and EPICS. For the accelerator projects SPIRAL2 at Ganil in Normandy and IFMIF/LIPAc at JAEA/Rokkasho (Japan) the EPICS control systems were based on VME. For 5 years our Institute has been involved in several in-kind collaboration contracts with ESS. For the first contracts (ESS test stands, Source and LEBT controls) ESS recommended us to use VME based solutions on IOxOS boards. Our close collaboration with ESS, their support and the requirements for new projects have led us to develop a standardized hardware and software platform called IRFU EPICS Environment based on microTCA.4 and MRF timing system. This paper describes the advantages of the combination of these recent technologies and the local control system architectures in progress for the SARAF project.

  The high power linac of European Spallation Source, ESS (Lund, Sweden), accelerates 62.5 mA of protons up to 2 GeV in a sequence of normal conducting and superconducting accelerating structures. The Medium Energy Beam Transport (MEBT) line has been designed tested and mounted at ESS Bilbao premises to guarantee tight requirements are met. The main purpose of this 3.62 MeV MEBT is to match the RFQ output beam characteristics to the DTL input requirements both transversally using quadrupoles, and longitudinally RF buncher cavities. Additionally, the beam is also cleaned by efficient use of halo scrapers and pulse shape by means of a fast chopper. Besides, beam characterization (beam current, pulse shape, size, emittance) is performed using a comprehensive set of diagnostics. Therefore, firstly, control integration of magnets and steerers power supplies, for quadrupoles, as well as synchronism, triggering, linked to high voltage pulsers within the chopper control, is part of the commitment for the present work. Secondly, the control developments of beam instruments such as Faraday Cup and Emittance Meter Unit will be described. All the integrations are based on ESS EPICS environment.
