Photomultiplier Tubes

A photomultiplier tube is a tube consisting of an evacuated envelope with a photocathode that emits electrons when exposed to light. These electrons are accelerated by a positive electrostatic field and fall upon a metal surface where they emit secondary electrons that are again accelerated to generate more electrons at the next metal surface.
