Abstract: The present invention relates to an X-ray tube with non-evaporable getters disposed therein for maintaining a degree of vacuum sufficient to operate the X-ray tube. The present invention provides a fixed-anode X-ray tube and a rotating-anode X-ray tube in which non-evaporable getters are disposed. The X-ray tubes, even when rated power is introduced without an aging process, can perform gas adsorption sufficiently and stably during operation, despite gases that can be generated by the filament and the cathode focusing cap and gases that can be generated by the target.

Abstract: An X-ray tube (1) comprising a cathode (3), an anode (5) and a further electrode (7) is proposed. Therein, the further electrode is arranged and adapted such that, due to impact of 'free electrons (27) coming from the anode (5), the further electrode (7) negatively charges to an electrical potential lying between a cathode's potential and an anode's potential. The further electrode (7) may be passive, i.e. substantially electrically isolated and not connected to an active external voltage supply. The further electrode (7) may act as an ion pump removing ions from within a primary electron beam (21) and furthermore also removing atoms of residual gas within the housing (11) of the X-ray tube (1). In order to further increase the ion pumping capability of the further electrode (7), a magnetic field generator (61) can be arranged adjacent to the further electrode (7).
