Abstract
835,118. Ion sources. SIEMENSCHUCKERTWERKE A. G. June 22, 1956 [June 27, 1955], No. 19487/56. Class 39(1). An ion source includes a nozzle 6 interposed between the cathode 1, Fig. 1, and the anode 10 and the pressure in the cathode space, defined by chamber 3, so differs from the pressure in the anode space 10 that a hightemperature arc discharge occurs in the space at higher pressure while a form of heavycurrent glow discharge occurs in the space at lower pressure ; the cathode is without separate heating means so that it is heated only by the discharge. The pressures in the spaces may be 40 mm. Hg and 10-<SP>3</SP> mm. Hg and the gas may be hydrogen. A plasma flow reaching supersonic speed may be produced. A negatively biased ion pull electrode or probe is provided at 7 and the anode has a nozzle aperture 9. Nozzle 6 may be provided with cooling channels. A second nozzle may be provided and the space between the two nozzles evacuated. The second nozzle may be of quartz and may be provided with cooling channels. In Fig. 4, the quartz nozzle 62 is mounted on the anode 64. The cathode, anode and pull electrodes may also be cooled. The anode and cathode may comprise magnetic poles in order to concentrate the plasma. The positions of the anode and cathode may be interchanged. In a modification the pull electrode is so shaped that the ion extraction takes place radially.
