What is the full form of MCP detector?

Microchannel Plate (MCP) Detector

Microchannel Plate (MCP) Detector refers to a sophisticated device used for detecting particles and photons with high sensitivity and temporal resolution. It is a key component in various scientific and industrial applications, including night vision technology, mass spectrometry, and space physics.

Construction and Working Principle

MCP detectors consist of numerous microscopic channels, typically made from lead glass, arranged in parallel and fused together. These channels, which are about 10 micrometers in diameter, are coated internally with a conductive material. When particles or photons enter these channels, they strike the walls, causing the emission of secondary electrons. These electrons are then accelerated and multiplied through a cascade process within the channels, leading to a detectable electronic signal at the output.
