2.5-D numerical simulation of high-current ion induction linac

The 2d3v particle-in-cell simulation results of transport and acceleration of hollow high-current ion beam (HCIB) compensated by electron beam in 1-5 magnetoinsulated accelerating gaps are presented. The possibility of HCIB transport through 1-5 cusps is demonstrated. It is shown that the HCIB distribution function quality on an accelerator output can be essentially improved with growth of an accompanying compensating electron beam energy. It is demonstrated that the injection of additional high-current electron beams in cusps leads to increase of accelerated ion beam monochromaticity and to reduction it divergency
