Abstract
An improvement to an existing crossed-field amplifier is shown which includes the replacement of an existing thermionic emitter with a larger platinum emitter. The platinum emitter is cooled from a surface opposite to the surface upon which a high voltage is applied to permit the form of the existing crossed-field amplifier to be maintained.
