HIGH CURRENT TANDEM ACCELERATOR FOR INTENSE MONOCHROMATIC GAMMA RAYS GENERATION

Original 2 MeV proton tandem accelerator with current 10 mA for monochromatic 9.17 MeV gamma-quantum production on Carbon-13 target for contraband detection is described. The tandem is supplied by a powerful sectioned rectifier from ELV type industrial accelerator providing high stability of the proton beam in the region of maximum gamma rays production at protons energy 1.75 MeV. Variants of gas stripper system and design of 100 kW Carbon-13 target with liquid metal cooling are presented. Also the results of optics calculation for focussing on stripper of 10 mA compensated H- beam with heterogeneous density and transverse energy about 1 eV are given.
