| abstract | 884,719. Thermonuclear apparatus; discharge apparatus. UNITED STATES ATOMIC ENERGY COMMISSION. Jan. 27, 1960 [Jan. 29, 1959], No. 2842/60. Classes 39(1) and 39(4) A method of forming an energetic ion plasma comprises establishing a magnetic field along the axis of an evacuated container, establishing magnetic minor fields at each end of the container, initiating and sustaining a gas fed arc discharge coaxial with the axis, and maintaining a radial potential gradient normal to the surface of the arc discharge to accelerate ions therefrom and electrons thereto. In Fig. 1 an anode 2 and cathode 1 are arranged on the axis of a cylindrical container 5, and two ring shaped cathodes 6, 7 and a cylindrical anode 22 are provided within the container. All the cathodes are of the gasfed type and may be supplied with deuterium and/or tritium from gas sources 18, 14 and 15. The discharge space is surrounded by coils 21 and minor coils 19, 20 are provided at each end. Electrodes 1 and 2 may be cooled by cooling tubes 107, 108 and baffles 111, 112 may be mounted in front of them; baffles and cooling coils (not shown) may also be provided for electrodes 6 and 7. The end spaces of the container 5 may be evacuated through ducts 25, 26 and the discharge space through duct 27. In operation gas is fed to the cathodes until the pressure at the cathodes reaches 3 x 10<SP>-3</SP>mm. and the discharges are initiated by connecting R.F. sources in parallel with D.C. sources to the electrodes; after the arcs are struck the R.F. sources are disconnected and the pressure in the discharge space is reduced to 5 x 10<SP>-5</SP>mm. the pressure in the end spaces being 3 x 10<SP>-4</SP>mm. A high potential difference of 20-50 kV is maintained between the arcs, the inner one being negative, for example, so that electrons diffuse from the inner arc to the outer one and ions from the outer to the inner. Either of the arcs may be replaced by a solid electrode as in Fig. 5 (not shown) or may be of hollow instead of solid form, Fig. 3 (not shown). Specifications 673,424, 853,916 and U.S.A. Specifications 2,197,079, 2,920,235 and 2,927,232 are referred to. |
