How do scintillator detectors work
A scintillation detector or scintillation counter is obtained when a scintillator is coupled to an electronic light sensor such as a photomultiplier tube (PMT), photodiode, or silicon photomultiplier. PMTs absorb the light emitted by the scintillator and re-emit it in the form of electrons via the … See more A scintillator is a material that exhibits scintillation, the property of luminescence, when excited by ionizing radiation. Luminescent materials, when struck by an incoming particle, absorb its energy and scintillate (i.e. re … See more Scintillators are used by the American government as Homeland Security radiation detectors. Scintillators can also be used in See more Organic crystals Organic scintillators are aromatic hydrocarbon compounds which contain benzene ring … See more Heavy ions Scintillation counters are usually not ideal for the detection of heavy ions for three reasons: See more The first device which used a scintillator was built in 1903 by Sir William Crookes and used a ZnS screen. The scintillations produced by the … See more There are many desired properties of scintillators, such as high density, fast operation speed, low cost, radiation hardness, … See more Organic scintillators Transitions made by the free valence electrons of the molecules are responsible for the production of scintillation light in organic crystals. … See more WebScintillation detectors work through the connection of a scintillator material with a photomultiplier (PM) tube. The PM tube uses a photocathode material to convert each pulse of light into an electron, and then amplifies that signal significantly in order to generate a voltage pulse that can then be read and interpreted.
