    Introduction Photomultiplier tubes (PMTs) are a type of vacuum tube used to detect and amplify signals from individual photons. PMTs are known for their high sensitivity to light, fast response, and large amplification factors. Structure of a Photomultiplier Tube A PMT typically consists of three main components: Working Principle When a photon strikes the photocathode,…
