MICROCHANNEL PLATE ELECTRON MULTIPLIER AND APPLICATION OF SAID MULTIPLIER TO RADIATION OR PARTICLES DETECTING DEVICES

摘要

An electron multiplier includes a micro-channel plate (12) having secondary electron emission. The channel plate is fitted in an annular metal frame (16, 17) which is in direct electrical contact with one (13) of the metallizations (13, 14) on the faces of the channel plate. The frame constitutes the means to apply an electric potential to one of the faces of the channel plate. The means to apply an electric potential to the other face of the channel plate are constituted by metallic contact studs (25) fixed in an insulated manner on the metallic frame and connected to the metallization (14) of the other face by means of conductor wires (30). The multiplier is incorporated in a detector device, the frame being soldered to the body (45) of the device by means of rods (48) traversing the body and soldered thereto.
