What are the differences between a photomultiplier tube and an electron valve?
A photomultiplier tube is a type of electric valve.
Thermionic valves (known as tubes in the USA) have been designed to do carry out a large number of functions, from amplifiers and rectifiers throught to display devices (CRTs), The detection of low levels of light using the photomultiplier effect is just one of these.
