The photomultiplier tube
WebbThe photomultiplier tube output in the photon counting mode is extremely small. This requires a photomulti-plier tube having a high gain and an amplifier with suf-ficiently low noise relative to the photomultiplier tube output noise. As a general guide, photomultiplier tubes should have a gain of approximately 1 × 106 or more. Webb12 feb. 2016 · A photomultiplier tube, useful for light detection of very weak signals, is a photoemissive device in which the absorption of a photon results in the emission of an electron. These detectors work by …
