Abstract
A high-perveance steady state deuterium ion gun was developed using a magnetic-index resonator in an Inductive Coupling Radio Frequency (ICRF) configuration. This approach made it feasible to generate an ion beam within millimeter dimensions extracted by negative potential placed at several centimeters from the exit of the ion source. The ion gun allows high extraction efficiency and low beam divergence as compared to other approaches.
