Micro Channel Plate (MCP) is a circular-plate device that amplifies electrons (signals).
It is contained in a two-dimensional detector of signals such as ions, photons, charged particles, and radiations (X-rays, gamma rays, etc.).
In some cases, detection devices employing MCPs are also referred to as MCPs.A microchannel plate consists of a highly insulating material about 2-mm thick with many small holes (microchannels) penetrating through it. The diameter of these holes is approximately 10 μm and they are spaced about 15 μm apart. A DC voltage of approximately 100 V is applied to the incident surface of this plate.

When a charged particle or photon strikes the incident surface of the plate, an electron is ejected. When these electrons hit the channel wall, they are amplified by the avalanche effect. The amplified electrons are detected by electrodes and fluorescent plates on the opposite side of the incident side.

Microchannel plates are used for Secondary-Ion Mass spectrometry (SIMS), Scanning Electron Microscope (SEM), and X-ray imaging, as well as ion detectors for night vision devices and time-of-flight Mass Spectrometry (MS)s.
