The Soreq Applied Research Accelerator Facility (SARAF) is a 5 - 40 MeV, 0.04 -2 mA proton/deuteron RF superconducting linear accelerator, which is under construction at Soreq NRC and is planned to start generating a beam by the end of 2010. SARAF will be a multi-user facility, whose main activities will be neutron physics and applications, radio-pharmaceuticals development and production, and basic nuclear physics research. The operational concept of SARAF will be ‘one target at a time’ and during irradiation, appropriate shielding will enable preparation and maintenance at other stations. This paper presents the planned facility operation program, the planned operations group, the location and layout of the main control room and the architecture of the main control system, including its interfaces with safety and applications. Emphasis is given to the design considerations for each of the discussed subjects.

Soreq NRC recently initiated the establishment of SARAF – Soreq Applied Research Accelerator Facility. SARAF will be a multi-user facility for basic, medical and biological research, non-destructive testing (NDT) and research, development and production of radio-isotopes for pharmaceutical purposes. An on going major activity is research and development of high heat flux (up to 80 kW on a few cm2) irradiation targets. SARAF is based on a continuous wave (CW), proton/deuteron RF superconducting linear accelerator with variable energy (5–40 MeV) and current (0.04-2 mA). SARAF is designed to enable hands-on maintenance, which implies beam loss below 10-5 for the entire accelerator. The commissioning of the Phase I of SARAF (full current, energy up to 4-5 MeV) is taking place during 2006 at Soreq. This paper describes the SARAF project and presents commissioning of the normal conducting injector (i.e., ECR ion source and RFQ). Test results of the β=0.09 half wave superconducting resonators are presented, and resonator geometry improvements with respect to electron multipacting behavior is discussed. An outlook on the project regarding reaching the final energy of 40 MeV is given.

A prototype superconducting accelerating module housing six 176 MHz half wave resonators and three superconducting solenoids is currently under production at Accel as part of a 40 MeV linear accelerator at the Soreq NRC. The module will accelerate protons and deuterons from energy of 1.5 MeV/u up to 6.5 MeV. The design is based on a peak electric field gradient of 25 MV/m and maximum 10 W of power dissipation in the helium bath by each cavity. Main design considerations of the cavities, solenoids, tuners and couplers as well as for the module especially in view of assembly and alignment will be presented. First cold cavity test results obtained in Accel’s new cold RF test facility will be presented. Prototypes of the tuner, helium vessel, solenoids and the couplers are under construction and partly under test.

Beam dynamics simulations of the SARAF (Soreq Applied Research Accelerator) superconducting RF linear accelerator have bean performed in order to establish the linear accelerator design. The multi-particle simulation includes 3D realistic electromagnetic field distributions, space charge forces and fabrication, misalignment and operation errors. A 4 mA deuteron beam is accelerated up to 40 MeV with a moderated rms emittance growth and a high real-estate acceleration gradient of 2 MeV/m. An envelope of 40,000 macro-particles is kept under a radius of 11 mm, well below the beam pipe bore radius. The accelerator design for SARAF is proposed as an injector for the EURISOL driver accelerator. The basic Accel 176 MHz β0=0.09 and β0=0.15 HWR lattice was extended to 90 MeV based on the LNL 352 MHz β0=0.31 HWR. The matching between both lattices ensures smooth transition and the possibility to extend the accelerator to the required EURISOL ion energy.
