Abstract
A thermionic generator (10) has a heated metal heat tube (11) journaled through a set of star-shaped emitters (12) and a set of electrically insulative spacers (13). The generator also has a collector (23) positioned about the grouped emitters and spacers a selected distance from the emitters. A cooling jacket (33) is positioned about the collector for cooling the collector during operation. A pair of seals (29) electrically and hermetically seal the cooling jacket about the heat tube.
