The photomultiplier tube also features fast time re-sponse and a choice of large photosensitive areas. Photomultiplier tubes (PMTs for short) are members of the class of vacuum tubes, and more specifically vacuum phototubes, which are extremely sensitive detectors of light in the ultraviolet, visible, and near-infrared ranges of the electromagnetic spectrum. Photomultiplier tube definition is - a vacuum tube that detects light especially from dim sources through the use of photoemission and successive instances of secondary emission to produce enough electrons to generate a useful current —called also photomultiplier. - Scintillation Detectors Brynle Barrett 3rd Year ...
