摘要
An MCP unit of the present invention has a triode structure with a structure to achieve a desired time response characteristic independent of restrictions from a channel diameter of MCP, and is provided with an MCP group, a first electrode, a second electrode, an anode, and an acceleration electrode. Particularly, the MCP unit further comprises an electron lens structure for confining reflected electrons emitted from the anode in response to incidence of secondary electrons from the MCP group, within a space between the acceleration electrode and the anode.
