How Does A Photocathode Work at Beau Bradley blog

How Does A Photocathode Work. At the dynode, the electrons are multiplied by secondary emission. The simplest form of the photocathode is a metallic surface, negatively biased, from which electrons are extracted by energetic photons. Photocathodes are materials, normally alkaline or multi alkaline metals, in which the impinging photons (normally in the near ultraviolet (uv),. Photocathode, an element of a photoelectric cell (q.v.) that emits electrons when struck by light, making possible the flow of electric current. • a semitransparent photocathode made of a thin layer of photoemissive material deposited on the inner surface of the window which emits electrons. Our informative page covers everything you need to know, from how photocathodes work to the families of materials used and their applications in particle accelerators and image intensifiers. A photocathode converts photons to electrons via the photoelectric effect.
