Abstract
1414501 X-ray tubes; electrode materials SIEMENS AG 3 Nov 1972 [4 Nov 1971] 50896/72 Heading HID X-rays are produced by electron beam incideuce on a rotary anode of a rotary anode X-ray tube, the anode comprising a body having a thin layer of material which is of higher density than the body and serves as an electron retarding layer, the thickness of the layer in the direction in which the electrons impinge being 0À5 to 5Á for W (or such as to provide an equivalent electron retardation if the material is not W) and is less than the penetration depth of electrons in the material of the layer at the acceleration voltage employed for the beam. The W layer may be 3 Á thick or 2 Á for a 50 to 80 kV beam, or 5 Á for an 80 to 150 kV beam. The body may have side by side layers 21, 22 on graphite body 20, both layers being of W and 2 Á and 5Á thick respectively (or providing an equivalent electron retardation if the material is not W) for respective acceleration voltage of 50 to 80 kV and 80 to 150 kV. Graphite body dimensions are given. In the above constructions some electron energy is absorbed in the support body and need not be transmitted from the higher density layer by thermal conduction so that cooling is improved. Also instanced are higher density layers of W alloy with Re or Os or Ir or a carbide of W, Ta or Hf.
