3 LBNL Detector

4 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)

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