Microchannel plate(MCP) is a special fiber optic element and secondary-electron multiplier which detects and amplified electrons in two dimensions.As MCP has the charecteristics of high gain,low noise, high resolution,low power,long life and the self-saturation effect, and it is sensitive not only to electrons but to ions,vacuum ultraviolet light,x-rays and Gamma-rays,making it useful in a wide range of detection applications
