SCINTILLATOR-LIGHT DETECTION

Physics

SCINTILLATOR-LIGHT DETECTION

1. The scintillator is coupled to a photomultiplier tube (PMT).
2. Key component which detects the visible light and produces a measurable electrical signal is the Photomultiplier Tube (PMT).
3. PMT converts light to electrons and then amplifies them.
4. The final signal strength is proportional to the energy deposited in the crystal (ie. the photon energy).
5. Signal produced by the PMT is then analysed by a PULSE HEIGHT ANALYSER (PHA).
