Abstract

See full text

A cathode assembly design is provided that includes two flat emitters, a longer emitter filament and a shorter emitter filament. In one implementation the focal spot sizes produced by the long and short emitters overlap over a range. Thus, one emitter filament may be suitable for generating small and concentrated focal spot sizes while the other emitter filament is suitable for generating small and large focal spots sizes.
