	CEA/Saclay is involved in high power proton accelerators for long years. This activity started in the 90's, with the development of the SILHI source which routinely produces tens mA of proton beam. Several industrial difficulties led to a very long IPHI RFQ construction process. The 352 MHz RFQ conditioning is presently in progress. Before the completion of the conditioning in CW mode, tests with pulsed proton beam have been decided. As a consequence, the SILHI source recently produced very short H⁺ beam pulses in order to allow the first IPHI beam acceleration. Such very short pulses, in the range of few hundred microseconds, allowed analyzing the beam loading of the RFQ cavity as well as conditioning the middle energy diagnostic. This article will focus on the source parameters and beam characteristics in the low energy beam line leading to the best RFQ transmission.

	The Facility for Antiproton and Ion Research (FAIR) located at GSI (Darmstadt) in Germany addresses several fields of physics research within a single installation. One of the contribution of Irfu/SACM at CEA-Saclay to the FAIR linear proton accelerator concerns the development and construction of the ion source and the low energy line. The 2.45 GHz microwave ion source will deliver a 100 mA H⁺ beam pulsed at 4 Hz with an energy of 95 keV. A low energy beam transport (LEBT) line based on a dual solenoids focusing scheme allows the injection of the proton beam into the radio frequency quadrupole (RFQ) within an acceptance of 0.3π mm.mrad (norm., rms). An electrostatic chopper system located between the second solenoid and the RFQ is used to cut the beam macro pulse from the source to inject 36 μs long beam pulses into the RFQ. This article reports the finalization of the installation of the injector with the detail of dedicated diagnostics, the first beam measurements and gives a planning of the different commissioning phases

The Facility for Antiproton and Ion Research (FAIR) located at GSI (Darmstadt) in Germany addresses several fields of physics research within a single installation. One of the contribution of Irfu/SACM at CEA-Saclay to the FAIR linear proton accelerator concerns the development and construction of the ion source and the low energy line. The 2.45 GHz microwave ion source will deliver a 100 mA H⁺ beam pulsed at 4 Hz with an energy of 95 keV. A low energy beam transport (LEBT) line based on a dual solenoids focusing scheme allows the injection of the proton beam into the radio frequency quadrupole (RFQ) within an acceptance of 0.3π mm.mrad (norm., rms). An electrostatic chopper system located between the second solenoid and the RFQ is used to cut the beam macro pulse from the source to inject 36 μs long beam pulses into the RFQ. This article reports the finalization of the installation of the injector with the detail of dedicated diagnostics, the first beam measurements and gives a planning of the different commissioning phases
