The Soreq Applied Research Accelerator Facility, SARAF, is currently under construction at Soreq NRC. SARAF is based on a continuous wave (CW), proton/deuteron RF SC linac with variable energy (5–40 MeV) and current (0.04-2 mA). Phase I of SARAF consists of a 20 keV/u ECR ion source, a low energy beam transport, a 4-rod RFQ, a medium energy (1.5 MeV/u) transport, a superconducting module housing 6 half-wave resonators and 3 superconducting solenoids, a diagnostic plate and a beam dump. Phase II will include 5 additional SC modules. The RFQ is in routine operation with protons since 2008 and has been further operated with molecular hydrogen and deuterons at low duty cycle. RF conditioning of the RFQ to enable deuteron CW acceleration is on going. The RF fields and dynamic cryogenic losses of the superconducting module have been measured with a VCO and the phase and amplitude stability at high fields has been measured with the SARAF LLRF system. Furthermore, proton and deuteron beams have been accelerated through the superconducting module. These were the first ever ion beams to be accelerated through half-wave resonators. Recent SARAF Phase I commissioning results will be presented.

Soreq Applied Research Accelerator Facility (SARAF) is a 176 MHz linac, currently under commissioning at Soreq NRC. Phase 1 of the accelerator includes a Prototype Superconducting Module (PSM), containing 6 half wave resonators. Over the last year some progress has been made in the commissioning of the PSM: a. For the first time a 3 mA pulsed proton beam was accelerated up to 2.2 MeV by a few of the resonators. Several diagnostic modules were used to measure the output beam and tune the resonators. b. Extensive investigation of the module was performed in order to analyze sources of microphonics. In addition, the tuner response was studied. c. He processing was applied, successfully reducing field emission.
