ABSTRACT:
An electron gun for generating an electron beam, comprising a cathode unit composed of at least a cylindrical cathode shaft having an end surface which forms an emissive surface. The cathode shaft is surrounded at least partly by a cylindrical metal heat reflection screen which extends beyond the open end of the cathode shaft. The cathode shaft and the heat reflection screen are secured in a cathode support, wherein the cathode shaft is suspended in the heat reflection screen so as to be self-supporting by means of metal strips or wires which are secured to the cathode shaft near the emissive surface and to the cathode support. This arrangement increases thermal efficiency and decreases warm-up time.
