abstract
A x-ray tube comprises a cathode cup assembly. The cathode cup assembly comprises a filament positioned in a cathode cup. A surface of the cathode cup assembly is exposed to incident infrared radiation, and the surface is adapted to reflect a substantial portion of the incident radiation, in which the radiation has a wavelength in a range from about 0.2 m to about 5.0 m.
