Abstract

1,133,034. Ion pumps. C. L. HALL. 17 May, 1966 [13 Sept., 1965], No. 21789/66. Heading H1D. An ion pump has an electron emitting filament 25 disposed within a hollow elongated electrode 23 maintained at a negative potential with respect to the filament, at least one pellet 32 of getter material, and means for connecting said pellet to a source of positive potential. The pump shown contains two pellets 32 and 33 which are arranged symmetrically with respect to the longitudinal axis of the tube, and may lie anywhere within a sphere 30 having its centre in the plane of the end surface 29 of electrode 23. The tube has a second reserve filament 26. The pump may be used as a vacuum gauge by connecting a current meter in series with the ion collecting electrode 23.
