  • Channel plate electron multipliers
    Patent number: 4886996
    Abstract: A method is provided for bonding glass channel plates (1,8) together in a stack, with the channels (2) of one plate being at an angle to the channels (9) of an adjacent stack to reduce optical and ion feedback. A layer of indium (4,10) is provided on plate faces to be bonded, bonding being achieved by applying pressure and a temperature between 130.degree. C. and 350.degree. C. A mechanically rigid and electronically stable channel plate electron multiplier is obtained for use in particle or photon counters or in raster intensified cathode ray tubes.
