ABSTRACT:
Apparatus is disclosed for generating high density pulses of electrons thermionically. The apparatus includes a metallic target maintained within a low pressure cesium vapor atmosphere. A laser rapidly heats the cesiated target surface to a high temperature in a time short compared with the residence time of cesium atoms adsorbed on the target surface. This rapid surface heating in combination with the adsorbed cesium atoms emits copious quantities of electrons forming a high current density pulse.
