    摘要: 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).

    摘要: A thermionic electron emitter (1) is proposed comprising an inner part (2) including a heatable flat emission surface (3) and an outer part (4) including a surrounding surface (6) substantially enclosing the emission surface and a heating arrangement for heating the emission surface to a temperature for thermionic electron emission. The outer part is mechanically connected to the inner part in a connection region (10) apart from the emission surface. Furthermore, the surrounding surface is thermally isolated, e.g. by a gap (14), from the emission surface in an isolation region apart from the connection region. By providing a surrounding surface enclosing the emission surface which may be on a similar electrical potential as the emission surface but which can have a substantially lower temperature than the emission surface without influencing the temperature distribution within the emission surface, an improved electron emission distribution and homogeneity can be obtained.
