  CEA is committed to the design, construction and commissioning of a Medium
Energy Beam Transfer line and a superconducting linac (SCL) for SARAF
accelerator in order to accelerate 5mA beam of either protons from 1.3 MeV to
35 MeV or deuterons from 2.6 MeV to 40 MeV. The Low Level RF (LLRF) is a
subsystem of the CEA control domain for the SARAF-LINAC instrumentation. The
top level requirement of the LLRF system has been presented in the last LLRF
conference. The paper shows a simulink model to analyse and determinate the
LLRF technical specification. The public bidding for SARAF LLRF is in the last
phase: discussion with the selected company. The first prototype test will be
performed at the start of 2020.
