Abstract

A major requirement for the SARAF accelerator [1] is 'hands-on' maintenance, which implies a maximum beam loss of 1 nA per meter. In Phase I of SARAF (4-5 MeV ions at 2 mA), we need to map the beam halo (BH) down to below 1 nA in order to predict, using beam dynamics calculations, the beam loss in the full accelerator. Mapping the halo of a 4 MeV, 2 mA ion beam down to below 1 nA is unprecedented. We have therefore developed a BH monitor, which incorporates a direct charge measurement as well as several nuclear techniques, including Rutherford scattering on gold, ⁷Li(p,n)⁷Be leading to both neutrons and the radio-isotope ⁷Be (measured offline post irradiation) and ¹⁹F(p,α)¹⁶O leading to high energy gamma rays, with the BH current being derived by using published cross sections. In this paper, we present the SARAF Phase I BH monitor and describe the various measurement techniques. In addition, results of feasibility studies at the Koeffler Pelletron accelerator of the Weizmann Institute are given.
