Abstract

905,428. Discharge apparatus. UNITED STATES ATOMIC ENERGY COMMISSION. June 1, 1959 [July 15, 1958], No. 18550/59. Class 39 (1). An electric arc discharge device has feed gas supplied to the cathode, a magnetic field parallel to the common axis of anode and cathode or, in the case when both electrodes are curved, following the curved electrode axes, and cooling means for both anode and cathode. In one form, Fig. 1, a cup-shaped tungsten anode 2 and tungsten cathode 3 are associated with floating shields 5, 6, 10 and with floating baffles 18, 19. Carbon anodes are disadvantageous. The gas is preferably deuterium or tritium but may be air, hydrogen, argon, nitrogen or helium. A suitable operating pressure is 3 X 10<SP>-5</SP> mm. Hg or lower. 33 are water cooling tubes for both anode and cathode. An RF voltage source 31 is used for starting, a hollow arc being initiated between the tips of the electrodes 34-35 and then the gas feed is reduced so that the arc moves into the interior of both anode and cathode. Complete space charge neutralization occurs within the hollow cathode but not in the main arc volume. Electrons are emitted radially from within the cathode. The gas is completely ionized within the cathode. In modifications, the anode may be solid and may rotate. The arc may be enlarged at its central part, the theory being given. In another embodiment, Fig. 3 (not shown) there are two tungsten cathodes with a central cylindrical anode. Floating cathode. shields and electron reflectors are disposed adjacent each cathode. A floating plate may be substituted for one cathode of Fig. 3 (not shown). In another embodiment, Fig. 4 (not shown) the cathode is a cylinder bent arcuately and the anode an incomplete toroid having a number of magnet coils wrapped around it. The embodiments of Figs. 3 and 4 (not shown) may be used as sources of energetic ions and electrons and for the dissociation of molecular ions. The arc discharges are not hollow in these embodiments. A portion of the discharge away from the electrodes can be " pinched off " by magnetic coils to make it more intense so as to ignite a thermonuclear plasma. Specifications 853,916 and 858,734 are referred to.
