Characteristics of reflex discharge ion sources
Investigations of the underlying principles of two types of reflex discharge ion sources are being carried out in this laboratory. The sources are the P. I. G. discharge source with self heated cathodes in a uniform magnetic field, used for production of multiply charged ions, and the directly heated cathode, reflex arc with an axisymmetric divergent magnetic field, for the production of light ions. A review is given of the investigations of these sources, showing how they developed from previously published studies of ion sources, with particular emphasis on a comparison drawn between their operating conditions and the role of energetic and thermal electrons in ionizing the neutral gas. Discussion is limited to the problem of the steady state equilibrium, and problems of stability are not considered. (auth)
