ABSTRACT:
An electron beam scan conversion method and apparatus based on the gain recovery or "dead" time characteristic of channel electron multipliers. The waveform of an electrical signal is written on the input face of a channel multiplier plate with an electron beam. Then, within the dead time of the written channels (typically about 1-100 msec.), the plate's input face is scanned in a predetermined raster pattern with a constant current beam. During the scanning step, an output signal is derived that corresponds to the difference in emission in response to the scanning beam between the channels in the written area of the plate and those outside that area.
