Source: Wikipedia Understanding Photomultipliers: A Comprehensive Guide Construction and Operation Principle Photomultipliers are photoemissive detectors with high sensitivity due to an avalanche multiplication process. They consist of a vacuum glass tube where light is absorbed on a photocathode, generating free photoelectrons. These electrons are then accelerated to dynodes, where they multiply several times before being
