Measurement of Energy Distribution of Output Electrons From a Microchannel Plate Based on Vacuum Photodiode

The energy distribution of output electrons (EDOE) from a microchannel plate (MCP) is measured using electrons emitted by a vacuum photodiode excited by a 266 nm Ti-sapphire femtosecond laser. The photoelectrons emitted from the photocathode are focused on a specific location of the MCP by a magneti...
