Microchannel plate (MCP)
IUPAC RECOMMENDATIONS 2013
microchannel plate channel electron multiplier array Thin plate that contains a closely spaced array of channels each of which acts as a continuous dynode particle multiplier. A fast charged or neutral particle, or a photon, that strikes the plate causes a cascade of secondary electrons that ultimately exits the opposite side of the plate.

-An incident x-ray photon enters a channel and frees (via "photoelectric emission") an electron from the channel wall. An electron accelerating potential difference (approx. -1500 Volts) is applied across the length of the channel. The initial electron strikes the adjacent wall, freeing several electrons (via "secondary emission"). These electrons will be accelerated along the channel until they in turn strike the channel surface, giving rise to more electrons. Eventually this cascade process yields a cloud of several thousand electrons, which emerge from the rear of the plate.
