The inertial electrostatic confinement (IEC) device provides 10{sup 7} 2.5-MeV D-D neutrons/second, when operated with a deuterium discharge at 70 kV. This potentially provides an important portable neutron source for various activation analysis applications. The discharge involved is unique, in that it uses a spherical grid in a spherical vacuum vessel. The discharge is struck between the grid and the vessel wall, and the 70-kV grid also serves to extract high-energy ions. Two features of the discharge are discussed: (1) the breakdown voltage characteristics as a function of pressure-grid/wall distance (pd); and (2) the formation of ion {open_quotes}microchannels{close_quotes} that carry the main ion flow through grid openings.
