Definitions

  • An object of the invention is to reduce the above-mentioned difliculties of properly insulating the acceleration means of a discharge device for producing rapid ions.
  • Another more particular'object is to provide a discharge device of the type here in point, which is puncture-proof at extremely high acceleration voltages, for instance above 1000 kv., while maintaining an economic output of rapid ion rays.
  • An object, in conjunction with the foregoing, is to provide an economically operating high-voltage discharge tube for producing ions of high speed, which tube is of simple construction and composed of relatively few parts of convenient dimensions.
  • a single highvoltage discharge gap of a tube for producing rapid ions has its anode and cathode insulated from each-other by several preferably cylindrical insulators which are separated from one another by circular sheet metal plates. These circular plates, which are impressed with suitable voltages, are associated with sheet metal cylinders which extend inside the insulator towards the cathode and have such diameters that each cylinder lies substantially in the equipotential surface corresponding to its voltage. In this manner it is possible to attain a puncture-proof tube even at very high total voltages above 1000 kv.
  • a discharge device for producing corpuscular rays of high velocity, in combination, two spaced electrodes of different polarity, a plurality of insulators arranged in series relation between said electrodes, a plurality of metal plates arranged between said insulators, each plate separating two adjacent insulators from each other, conductor means for separately applying progressively graduated voltages to said electrodes and plates respectively, and a plurality of metal cylinders connected with said plates respectively and surrounding one of said electrodes, all of said cylinders having diflerent diameters and lengths, the diameters being graduated in accordance with the graduation of said voltages, each of said cylinders extending from its appertaining plate towards said other electrode substantially in conformity with the equipotential surface corresponding to the voltage of said plate, the lengths of said cylinders being also graduated so that the outer cylinder approaches said other electrode to a greater extent than the inner cylinder.
  • an anode unit forming a source of ions, a cathode for accelerating the ions emitted from said anode, a plurality of tubular insulators series-arranged between said anode unit and said cathode, circular metal plates arranged between said insulators, each plate separating two adjacent insulators from each other, conductor means separately connected with each of said anode, plates and cathode for applying graduated voltages to said anode, plates and cathode respectively so as to have the total voltage effective between said anode and cathode, and sheet metal cylinders associated with said plates respectively and surrounding said anode, all of said cylinders having different diameters progressively graduated in accordance with the graduation of said voltages, and each of said cylinders extending from its appertaining plate towards said cathode substantially in conformity with the equipotential surface corresponding to the voltage of said plate, said cylinders further having different lengths, the cylinders associated
