Abstract

995,188. Electron multipliers; mass spectrometers. BENDIX CORPORATION. Sept. 23, 1963 [Sept. 28, 1962], No. 37386/63. Heading H1D. A spatial discriminator for analyzing the cross-section of a particle beam comprises an array 10 of channel electron multipliers of the kind disclosed in Specification 950,640, each channel receiving a different part of the beam, and an anode disposed at the output end of each channel to detect separately a signal produced by the particles entering that channel. As shown, the discriminator is used in a mass spectrometer, ions from source 1 being deflected by a magnetic field so that ions of the same mass enter the same column of channels in the multiplier array 10. The anodes comprise wires 18, 24 &c. passing through an insulating base 16, and the anodes of each column of channels are connected to a common terminal and to an ammeter 22, 40 &c. The discriminator may also be used to determine the cross-section of experimental molecular beams, or beams produced by particle accelerators.
