Abstract
862,835. Ion sources. UNITED STATES ATOMIC ENERGY COMMISSION. May 19, 1959 [July 9, 1958], No. 16927/59. Class 39(1). An ion source comprises a vacuum chamber, means 8, 9 for establishing a magnetic field therein, means for initiating a gas-fed arc discharge 7 within the chamber with the axis of the arc parallel to the direction of the magnetic field, and means for maintaining a selected pressure gradient between the arc discharge and the volume surrounding the discharge. It is stated that this results in the establishment of time-varying electric fields in the region of the discharge wherein some of the electrons are accelerated and their increased energy is transferred to the ions in the surrounding volume. For example, the gas-feed through feed pipe 5 may be such that the pressure near the filament 1 is 10<SP>-3</SP> mm. Hg and the pressure in the outer regions is maintained by a pump at about 10<SP>-5</SP> mm. Hg. Deuterium hydrogen and nitrogen may be utilized as feed gases. The discharge is struck between a heated filament 1 and a floating electron reflector 2 and a pair of earthed apertured collimating electrodes 3, 4 is located between the electrodes 1, 2. The arc may be pulsed.
