Abstract

Simulation results for three different neutralization channel designs of a fast neutral beam (FNB) source are presented and discussed. The influence of channel geometry on the FNB generation efficiency is studied. A direct channel design characterizing by technological simplicity has a low ions-to-neutrals conversion coefficient. For an inclined channel design a strong effect of the ions and fast neutrals angle separation is found. With angle restricting the output beam, this effect provides increasing the neutrality degree due to eliminating most of ions from the output beam. The results obtained for a design with addition reflecting surfaces predict a high efficiency of the proposed channel due to a focusing effect providing a high particle density in the beams overlap area.
