WebApr 3, 2024 · Photomultiplier tubes (PMTs) are a photon detection device that uses the photoelectric effect combined with secondary emission to convert light into an electrical signal. A photomultiplier absorbs light emitted by the scintillator and re-emit it in the form of electrons via the photoelectric effect. WebA photomultiplier tube (PMT) consists of a photocathode followed by an electron multiplier. A single photon ejects an electron from the photocathode. Electric fields in the PMT … WebIn considering the behavior of a photomultiplier tube, a drawing may be helpful. The resistive voltage divider provides potential to each of the electrodes (photocathode, dynodes) except for the anode, which is maintained at virtual common by external circuits. salary google director
