Abstract

914,392. Ion sources. PHILIPS GLOEILAMPENFABRIEKEN N.V. Sept. 11, 1961 [Sept. 14, 1960], No. 32542/61. Class 39 (1). An ion source for a synchro-cyclotron has a metal gas chamber containing a cathode 13 and provided with a nozzle 4 in which there is a primary bore 6 and a number of converging secondary bores 7, the arrangement being such that when an electric discharge is produced between the cathode and the gas chamber, electrons and ions moving helically around the magnetic lines of force of the synchro-cyclotron (direction B) emanate from the primary bore into the high-frequency electric field between the cyclotron cleet 1, 2, between a third and a fourth of the total supply of gas passing through the secondary bores. The gas may be deuterium at a pressure of 10<SP>-2</SP> mm. of mercury. Helium is also referred to. Gas is supplied to the gas chamber at 10 and the secondary bores may be supplied with gas from the gas chamber or from a separate supply pipe 9. The cathode 13 is a renewable tungsten pin fitted in a copper block 12. Water-cooling pipes are shown at 11 and 14. A porous tungsten face plate 5 protects the nozzle 4 from ion bombardment.
