Definitions

  • This invention relates to Xray to an installation for operating same.
  • a high tension transformer is frequently employed, the prim'ary wind-- 6 ing of which is connected to a source of low tension.
  • these-,transformers occupy much spiace and are rather. expensive.
  • a coil around an X-ray tube is 'wound a coil the ends of which may be electricall connected to the 2@ cathode and the anticat od Y .rent to be generated therein.
  • the lli-ray vtube may be rovided with a second coil which surroun the othei ⁇ coil and serves to generate the high tension.
  • - llli S5 is arranged clon the axis of the Xray tube inside the secon a coil wound on the wall roi-the X-ray tube. or this if necessary, a cavity may be provided in the anticnthode along the axis of the X-ray tube, or
  • c@ the iron core may be arran ed in the interiory ofi the anticathode tube.
  • Xus/ay' tubes constructed in this manner can be perated with currents having a ⁇ iirecluency o, ier example, 500 periods.
  • An incandescent cathode 2 in the form of a stretched wire is arranged within a metal vessel 1 which-'maybe made of chrome iron forming art of the envelope of thetube and to the w l of which is secured a metal.
  • cover 3 havin an aperture in front of which is arrang ananticathode 4, part of whose surface is opposite this aperture.
  • Thiswin ow consists of a glass hood 5 which is hermetically sealed to the metal wall.
  • An annular metal plate 6, for example of iron serves to screen the X-rays and has secure to it the leading-in wires for the incandescent cathode.
  • One leadingin wire 7 for the lincandescent; cathode is led through the metal ring 6 from which it is insulated, andis sealed into the glass hood ⁇ 5.
  • the .other leading-in wire is constituted b the conductive connection of a pole 8 wi the metal ring 6 and by the metal envelope 1.
  • the cathode rays emitted by the incandescent cathode can. strike the anticathode only on a limited surface owing to the particular shape of the wall and of the cover 3 of the metal ment of the antcatlio relatively to the said cover.
  • To the metal vessel l. is sealed a reentrant glass tube 9 to the end of which is sealed the anticathode 4f.- Around the up per end of the anticathode is arranged a Acooling device 10.
  • a coil 11 which at one of its ends is connected to the metal vessel land thus is electricall 'connected to the incandescent cathode an which 'at its other end is in conductive connection with the anticathode.
  • this coil 11 is provided asecoiid coil 12 which is separated from the former b insulating materi ⁇
  • the ends o the coil 12 can be connected ⁇ to a source of high frequency tension vconsisting, for exam le, of an oscillatory circuit in which big frequency oscillationsare generated by means of a transmission tule as used1 fog, rladiotelera hic ur s.
  • t is evi en owever, tghai? the higlliiogequency oscillations may be lgenerated in any other known manner as a spark gap or bymeans of an arc.
  • the coil 11 consists of a single layer of 500" turns and if the coil 12 contams 10 turns, the tension of the-tube gener-- len h of 10,000 metres.
  • An'X-ray tube characterized in that around the tube is wound a coil the ends of which are electrically connected to the cathode and to the anticathode, said coil being adapted to permit a high tension current to be enerated therein.
  • An -ra tube according to claim 1 characterized 'y a second coil which surrounds the' other coil and serves to generate the high tension.
  • An X-raytube characterized in that around the tube is wound a coi1,the ends of whichv are electrically connected to the -cathode and to the'anticathode, said coil being adapted to erm'it a high tension current to be generate therein, an iron core being larrangedinside said coil about the axis of the X-ray tube.
  • X-ra tube characterized in that around the tu is wound ⁇ a coil the ends of which are electrically connected to the cathode and to the anticathode, said coil being adapted to permit a high tension current to be generated therein, an iron core being arranged inside said coil in the interior of the anticathode tube.
  • An X-ray tube installation comprisin an X-ray tube, a coil being wound aroun said tube, the ends of said coil being electrically connected to the cathode 'and to the anticathode, said coil being adapted to per 'Iht a high tension current to be generated tube accordin to claim 3,
