Abstract
This paper reports on the development of solid-state hybrid photomulti plier tubes using high quantum efficiency, transmission mode, III-V ph otocathodes, The first strike low-noise gain mechanism in these device s is provided via electron bombardment of a solid-state GaAs Schottky diode, In addition, a second-stage gain is provided by solid-state ava lanching within a GaAs Schottky APD (SAPD) anode, A combined gain of 2 x 10(4), adequate for photon counting, is achieved, Device bandwidth, exceeding 1 GHz, is optimized by tailoring the diode anode structure, The combined traits of this device provide high quantum efficiency, l arge dynamic range, large bandwidth, and adequate gain for photon coun ting, Photon counting beyond 1 mu m is feasible for a cooled device, T he tube structure, diode anode structure, noise issues and preliminary photon counting results are discussed.
