<p>Photomultipliers are disclosed which comprise circuitry for detecting photo electric events and generating short digital pulses (110) in response. In one embodiment, the photomultipliers comprise solid state photomultipliers (40) having an array of microcells (46). The microcells (46), in one embodiment, in response to incident photons, generate a digital pulse signal (110) having a duration of about 2 ns or less.</p> |
