dynode

[dī′nōd]
one of a series of platelike elements that amplify electron pulses in a photomultiplier tube. Each electron that strikes a dynode causes several secondary electrons to be emitted. The dynode gain is the ratio of the number of secondary electrons to the number of incident electrons.

Among the breakthrough claims of the patent is the application of an engineered thin film dynode layer applied to microchannel plates which enhance their performance in many key areas including higher gain, lower dark noise, and longer effective lifetime.
The high measured gain was demonstrated by applying Arradiance's patent-pending GEM-D2[TM] thin film dynode process to a standard, commercially available, 60:1, 12 micron pitch, 12x bias angle microchannel plate.
