photoemissive detector

Also contains definition of: external photoelectric effect

A detector in which a photon interacts with a solid surface, which is called the photocathode, or a gas, releasing a photoelectron. This process is called the external photoelectric effect. The photoelectrons are collected by an electrode at positive electric potential, i.e. the anode.
