The role of charge exchange in IFR (ion focused regime) relativistic electron beam propagation
Charge exchange results in the transfer of momentum from an ion to a neutral atom, thus it is equivalent to a slowing down mechanism for ions. This might be helpful in IFR propagation of relativistic electron beams. The effect of charge exchange on the ion hose instability and channel expansion after beam passage is investigated in this report. For parameters of interest to current experiments, it is found that the effect on growth of the ion hose instability is insignificant, but there is significant reduction in the energy of the expanding ions after passage of the electron beam. 5 refs., 5 figs.
