Scintillators Scintillators are materials which emit light when they interact with charged particles. Usually a type of plastic that is doped with small amounts of aromatic hydrocarbons. (Polyvinyltoluene)

Photomultiplier Tubes  Photon Detectors  Operate on photoelectric effect  Amplification is obtained by a sequence high voltages applied across dynodes
