Abstract

818,182. X-ray tubes. GENERAL ELECTRIC CO. May 16, 1956 [May 18, 1955], No. 15257/56. Class 39(1). An X-ray tube target comprises a heat dissipating base plate 10 made of a material that is substantially transparent to X-rays, such as beryllium, aluminium or magnesium and a thin layer of tungsten 9 bonded thereon. The target may have a diameter of # ins., the base plate being 3 mils. thick and the tungsten layer 0À5 microns thick. The tungsten layer must form a good bond with the base plate and this may be achieved by heating the plate in a vacuum and passing tungsten carbonyl in a hydrogen stream over the plate. As shown the target is mounted at one end of an X-ray tube 1, the X-rays being emitted on the opposite side of the target from that which is bombarded by the electron beam 6.
