Abstract
1,138,212. Ion beam tubes. UNITED STATES ATOMIC ENERGY COMMISSION. 23 May, 1966 [16 June, 1965], No. 22808/66. Heading H1D. An ion beam generator, as shown, incorporated in a Van de Graaf accelerator, comprises a body such as a rod, or a wire 53 fed from a spool 54, which is vaporized to form a plasma of ions by subjection to a laser light beam. The laser beam is focused at a point e.g. about <SP>1</SP>/ 4 inch from the tip of the wire 53. The ions are extracted and accelerated by grid electrodes 70, 74 the latter being preferably convex-shaped. A focusing electrode 76 is provided between the source and the main accelerating tube 42. The tube 42 and the Van de Graaf sphere 31 may enclose a common evacuated space in which case tube end 61 is omitted. The target 78 may be within the sphere 38. As shown, the laser beam from the laser 63 is directed into the column 32 through a window 66, is reflected by a prism 67 and enters the accelerating tube end 61 through a lens 68. The ion emitter body may be of Al, C, Cu, Fe, Ni or Ta or may be a pool of liquid, e.g. mercury.
