Abstract

1,232,160. X-ray tubes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 18 Aug., 1969 [17 Aug., 1968], No. 41156/69. Heading H1D. An X-ray tube comprises a frusto-conical anode 4 which rotates about an axis normal to the incident electron beam path which is parallel to the cylindrical envelope. The anode block 4 may be of molybdenum or carbon surrounded by a tyre 9 of tungsten or tungstenmolybdenum or of a rhenium-tungsten-molybdenum layered material, and is secured to its shaft by members 10 which limit heat transfer to the bearings 7 which are arranged in a watercooled copper block 8. Blackened copper discs 12 are attached to the shaft and arranged in cavities 11 in the block to provide additional radiative cooling. A rotor 13 is provided at one end of the shaft and co-operates with external windings (not shown) through a ceramic disc 14 which prevents dissipation of the magnetic energy in the metal envelope 1. The envelope may be coated with lead shielding, and is provided with a beryllium window 17 close to the anode ; a ceramic insulator 3 carries the cathode 2 and a high-voltage connection fits closely inside the insulator. A centrally apertured metal screen 16 electrostatically screens the lower part of the tube except for the focal spot on the anode.
