Abstract

The paper deals with the design integration of two alternative solutions for the negative ion source and accelerator of the ITER neutral beam (NB) injectors. The first alternative concerns the new 1 MV accelerator, named SINGAP, which has a single acceleration step instead of the five steps of the reference design. The second modification introduces a radio frequency (RF) negative ion source replacing the traditional filament solution. Design criteria, solutions and critical issues are presented in the paper
