An easy method of making a parallel plate electron multiplier, which is used for detection of x-rays, electron beams, and charged particles, is developed. The multiplier consists of two continuous dynodes, which are prepared by evaporating aluminum onto glass substrates on which carbon has been evaporatedin advance. The gain is in the range of106to 109, when the applied voltage is 3 kV. Some of thefeatures are quite good linearity of response except for the saturation region, extremely small noiseand long lifetime, and ease in handling. It also can be used for the pulse count techniques. A briefreview of the outline of the continuous dynode electron multiplier is added.
