Abstract

971,770. Ion sources. HIGH VOLTAGE ENGINEERING CORPORATION. Nov. 28, 1962 [Dee. 11, 1961; June 18, 1962], No. 44959/62. Heading H1D. In an unoplasmatron ion source with filamentary electron-emitting cathode 8, Fig. 2, and intermediate electrode 9 disposed within a gas-supplied ionization chamber 36 of which the end wall is constituted by a small-apertured anode 11 and with, beyond the ionization chamber, an evacuated beam forming chamber containing an extractor electrode 15 and a focusing electrode 16, a relatively large apertured plasma control member 12 is provided between the anode 11 and extractor electrode 12 in order to permit expansion of the plasma and so secure a smaller divergence of the ion beam entering the lens 15, 16. It is therefore possible to obtain larger beam currents while restricting gas flow through the anode aperture. A magnet coil 7 shapes the discharge between filament 8 and anode 11. In another embodiment, Fig. 4, the plasma control member 35 is an extension of the anode and provides a drift space for the expansion of the plasma. A grid 37 may be provided to establish the plasma boundary.
