Definitions

  • a further increasing of the tube capacity is limited by the degree of heating of the anticathode, said heating being too high in spite of an intensive cooling.
  • This tube is adapted to operate at 650-500 ma. at 40-50 kv. during 0.05 second and at 500-400 ma. during 0.2 second.
  • the rod passes through the pump in such a manner that the space between these parts constitutes a diffusion diaphragm through which the air is exhausted by mercury vapours or the like flowing with great velocity out of an annular nozzle as in usual diffusion pumps.
  • the detachable junction between the shell I and the difiusion pump underneath it is effected by a gas-tight glass sleeve I0, hermetically drawn upon a metallic cone which is connected to the shell I by means of elastic member II.
  • the so formed glass receptacle I2 is filled with liquid air for freezing out the mercury vapours.
  • the revolving anticathode comprises the flat piece I3 firmly fastened to the through tubular rod I4.
  • the rod I4 of the revolving anticathode I3 is rotated from without by means of the toothed gearing I8.
  • V Thevacuumpumpis connected to the connecting'tube 25.
  • v r V Themercury vapours ascend from the boiling vessel 26 and pass" through the nozzles 21-which are arranged in parallel, and through the annu larnozzle on the part 22.
  • the stufling box is located in Such avacuum..makes surethe operation of' the four-stage difiusion pump.
  • a Roentgen tube including a rotary water cooled anticathodeand a carrying rod forisaid anticathode, a multi-stage .diflusion pump connected with said tube and having high 7 and low vacuum zones, said rod extending through said pump and externally, thereof through the low vacuum zone, a bearingitor said rod in the high vacuum zone of the pump, a bearing for said rod in the low vacuum zone and a water jet pump at a point where the rod extends through the multi-stage diflusion' "pump for creating a vacuum for the operation :01 the multi-stagedifiusion pumpand corresponding to .15-20 mmnof the mercurycolumn.
  • said multi-stage diflusion pump includes a diffusion diaphragm surrounding said carrying rod'in' the high vacuum zone oi v said diffusion pump.
