Abstract
An improved cathode assembly is disclosed. The improved cathode assembly provides a deep channel for holding filament that enables generation of small focal spots, but is not limited in achieving larger focal spot sizes. The cathode assembly includes at least one deep channel and a filament arranged in a deep channel. The deep channel is configured in a cathode cup surface of the cathode assembly. The filament is arranged in the deep channel for enabling emission of electron beams from the cathode assembly.
