Proposal of an electrostatic multi-stage accelerator for high-current pulsed ion beam

A new type of multi-stage accelerator is proposed to produce high-current-pulsed ion beam. In the accelerator, a pulsed high-current ion beam is accelerated without using induction cells. The accelerator is simple and a higher acceleration gradient is realized compared with an induction linac. The performance is demonstrated through the example of a ten-stage accelerator designed to accelerate a 50 MeV 100 kA, 50 ns beam of C+ ions to 60 MeV. The operation of the accelerator circuit was simulated by a computer code, which shows that acceleration pulses were successfully applied to each gap. PACS. 29.17. + W; 41.75.Lx.
