Each microchannel is a continuous-dynode electron multiplier, in which the multiplication takes abode beneath the attendance of a able electric field. A atom or photon that enters one of the channels through a baby breach is affirmed to hit the bank of the approach due to the approach actuality at an bend to the bowl and appropriately the bend of impact. The appulse starts a avalanche of electrons that propagates through the channel, which amplifies the aboriginal arresting by several orders of consequence depending on the electric acreage backbone and the geometry of the micro-channel plate. After the cascade, the microchannel takes time to balance (or recharge) afore it can ascertain addition signal.

The electrons avenue the channels on the adverse ancillary area they are themselves detected by added means, generally artlessly a distinct metal anode barometer absolute current. In some applications anniversary approach is monitored apart to aftermath an image. Phosphors in aggregate with photomultiplier tubes accept additionally been used.
