The design of the output structure of the static crossed-field photomultiplier

A static cross-field photomultiplier having wideband response is one of the promising photodetectors suitable for the optical PCM system that makes use of very short pulses generated from a mode-locked laser. For this purpose, special consideration is given to the realization of a high-quantum-efficiency photosurface and to the design of an output-structure by means of which a flat frequency-response extending from dc up to microwave frequencies can be obtained.
