    Abstract: A photomultiplier which can be easily made compact has a dynode unit having a plurality of dynode plates (6) stacked in an electron incident direction in a vacuum container fabricated by a housing and a base member integrally formed with the housing. Each dynode plate is constituted by welding at least two plates (6a,6b) overlapping each other. The welding positions (W) do not overlap each other in the stacking direction of the dynode plates. With this structure, field discharge at the welding portions between the dynode plates can be prevented to reduce noise.

    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°C amd 350°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.
