How does photomultiplier tube work
WebPhototube. A phototube or photoelectric cell is a type of gas-filled or vacuum tube that is sensitive to light. Such a tube is more correctly called a 'photoemissive cell' to distinguish it from photovoltaic or photoconductive cells. Phototubes were previously more widely used but are now replaced in many applications by solid state photodetectors. WebA photomultiplier tube (PMT) converts a light pulse into an electrical signal of measurable magnitude. An array of these tubes is situated behind the sodium iodide crystal and may be placed directly on the crystal, connected to the crystal by light pipes, or optically coupled to the crystal with a silicone-like material. ...

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. WebMay 8, 2024 · How does PMT work? 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 amplifying the electrons generated by a photocathode exposed to a photon flux.
WebA photomultiplier tube (PMT) is a type of vacuum tube that is used to detect light. It consists of a photocathode followed by an electron multiplier 1, which together amplify the electrical signal produced by a single photon of light. The PMT works by converting light energy into electrical energy.
