Abstract
A channel plate electron multiplier of the discrete dynode type formed from conductive sheets which are stacked in closely spaced relation. Each sheet is perforated with apertures which are aligned to form electron multiplying channels. The apertures in each sheet have input and output and cross sections which are approximately the same size and a concave shaped inner surface profile which causes a majority of electrons to strike the inner surface close to the output end, whereby the gain of the multiplier is increased.
