Gain of Electron Multiplier

Gain of Electron Multiplier

The gain control is performed by changing the high voltage applied to the first dynode. The applied voltages to other dynodes are automatically determined by the resisters mounted in the multiplier. The typical gain curve of a new multiplier is shown below. In general, the gain gradually decreases after operating the multiplier for a long time. It is better to avoid operating at unnecessary and excessive high gain to extend the multiplier’s life.
