Photomultiplier Tube A PMT consists of three basic elements: An input window capable of transmitting light over a particular spectral range that can span from the near UV to near IR with a photocathode deposited on its inner surface. photomultiplier tube intended for general purpose applications in low-lightlevel detection and measurement systems. Phototubes operate according to the photoelectric effect: Incoming photons strike a photocathode, knocking electrons out of its surface, which are attracted to an anode. Photomultiplier converts the light pulse into an electronic signal that is amplified by the electronics of the camera. From the signals received by the photomultipliers, the approximate position of the impact and the gamma energy are evaluated. Introduction. The photomultiplier's continuing superiority stems from three main features: — large sensing area — ultra-fast response and excellent timing performance — high gain and low noise Therefore, in the photomultiplier tube, they are attracted through a voltage drop of about 50 volts to the nearest dynode. 1 is a cross-sectional diagram schematically showing a conventional photomultiplier tube; FIGS.
