Heavy ion acceleration using charge exchange

To increase the intensity of ion sources a method of heavy ion acceleration in the MeV range using charge exchange on residual gas just after ions extraction from the sources is proposed. Calculations are carried out applied to a 4 MV electrostatic accelerator for a Bi+1 ion source. The charge distribution of ions at the end of accelerating tube at the residual gas pressure of 10-5 Torr and 10-4 Torr is given. The ion energy spectra is presented for every charge state. It is shown that using the charge exchange acceleration method ion beams can be produced in the electrostatic accelerator in wide energy and charge ranges. Such beams can be widely used for both physical experiments and beam accumulation with subsequent injection into high-power accelerators
