Photoemissive detector

  "id": "MLC-T-CHM-008866",
  "term": "Photoemissive detector",
  "field": "Chemistry",
  "definition": "A type of radiation detector that operates on the principle of the photoelectric effect, where incident photons cause the emission of electrons from a photosensitive surface. These emitted electrons are then collected and amplified to produce an electrical signal proportional to the incident radiation intensity. Photomultiplier tubes are a common example of this detector type.",
