Discrete dynode particle multiplier
Ion-to-electron detector in which the ion strikes the surface of an electrode and induces the production of secondary electrons. In turn, these impinge in sequence on dynodes at a more positive electric potential to produce more secondary electrons. This avalanche effect produces an amplification of several orders of magnitude in the final measured current pulse.
