International audience; For the Facility for Antiproton and Ion Research (FAIR) a compact proton linac will produce proton beams with energy of 68 MeV that will be injected into upgraded Heavy Ion Synchrotron (SIS 18), accelerated to 4 GeV, and further accelerated to 30 GeV in SIS 100. The commissioning of the proton injector which would serve for the injection into the proton linac has already started at CEA/Saclay. The ion source operating with a microwave frequency of 2.45 GHz based on Electron Cyclotron Resonance (ECR) plasma production with two coils each with 87.5 mT magnetic field, will deliver a 100 mA proton beam at 95 keV of energy. The Low Energy Beam Transport (LEBT) including two short solenoids system and integrated steerers will transport the proton beam to the RFQ entrance with an expected emittance lower than 0.3π mm mrad (normalized, rms). After the LEBT an electrostatic chopper will be mounted in front of RFQ to shorten the beam pulse to 36 µs. This paper presents the status of the commissioning phases including first results of proton injector.
