Phototubes
An expression for P n (T) follows from a consideration of the photodetection process, which begins with the ionization of a single atom by a single photon at the surface of the phototube any event, the rate of counting is proportional to the intensity of the light beam, so one writes αI(t)dt for the probability of counting a photon at the time t in the interval dt.
6.6: Photodetectors
The most common type of phototube is the photomultiplier tube. This device has multiple electrodes, and when an electron hits one of these electrodes, additional electrons are emitted. These electrons can hit additional electrodes to produce even more electrons. Because each incoming photon produces a cascade of electrons, photomultiplier tubes ...

Phototube Principle and Operation
A phototube or photoelectric cell is a type of gas-filled or vacuum tube that is sensitive to light. Such a tube is more correctly called a ''photoemissive cell'' to distinguish it from photovoltaic or photoconductive cells. Phototubes were previously more widely used but are now replaced in many applications by solid state photodetectors. The photomultiplier tube is one of …
photoelectric cell
In the phototube, an older type of photocell, two electrodes are enclosed in a glass tube—an anode and a light-sensitive cathode, i.e., a metal that emits electrons in accordance with the photoelectric effect. Although the phototube itself is now obsolete, the principle survives in the photomultiplier tube, which can be used to detect and ...

The fundamental use of a photocell is to convert a change in the intensity of illumination into a change in electric current. This change in electric current may be used to operate controls and in light measuring devices. For example, a person approaching a door way may interrupt a light beam which is incident upon a photo cell.
