Abstract

936,137. Discharge apparatus. UNITED STATES ATOMIC ENERGY COMMISSION. Feb. 26, 1962 [March 27, 1961], No. 7352/62. Class 39 (1). A plasma gun e.g. for space propulsion or for injecting plasma into a thermonuclear reactor comprises an ion source through which a beam of ion-neutralizing electrons are projected with sufficient energy to emerge with the ions. In Fig. 1 the ion source consists of an enclosure 14 and a cathode 16 and an anode 17 between which an arc discharge is struck in deuterium gas supplied at 18. A shield is provided at 15 and the outlet plate 20 has a tungsten insert 21. The electrode 22 between the outlet plate 20 and the extractor electrode 24 is electrically floating and is stated to increase the current output. The electron source includes a directly or indirectly heated filament 1, a hollow anode 2 to which argon is supplied through tubing 3 and a shield electrode 8 and accelerator electrode 10 which are connected together. A gas arc is struck between the cathode 1 and the anode 2. A collimating magnetic field H is provided. In a modification, Figs. 4 and 5 (not shown), the electron source comprises a hollow tubular cathode coaxial with a hollow anode. Gas is supplied to the rear end of the hollow cathode and a hollow arc discharge is struck between the cathode and the anode. A door may be provided to cover the inlet aperture to the ion source when the electron source is not required. In a complete plasma injector device, Fig. 2, the electron source 28 and ion source 65 are surrounded by collimating magnetic coils 52, 57 and intermediate coils 53 to 56 and further coils 58 to 61 which are provided have housings electrically connected to provide accelerating fields. To provide a higher density final plasma beam, coils 53 to 56 and 58 to 60 with associated accelerating stages may be eliminated, Fig. 3 (not shown). Specification 905,428 is referred to.
