Structure of Electron Multiplier (Continuous-Dynode Type)

The continuous-dynode type sometimes is in the shape of a horn. This type of multiplier is made by extruding lead-silicate glass. The multiplication principle is similar to the discrete-dynode type, but electrons are emitted from the continuous inner surface of the horn, instead of from a discrete metal dynode. There are no discrete resistors, because the film of the inner surface is a spatial resistance itself.
