Overview
Microchannel Plate (MCP) Gate Modules are used to gate an MCP ON by coupling a positive high voltage pulse onto the fixed bias of the MCP output electrode.
If multiple MCPs are used in a detector, the rear MCP is typically gated ON. In the normal OFF state the MCP bias is set below its working voltage. The MCP is turned ON when the high voltage pulse increases the MCP bias by 500 or 1000 volts.
The GM-MCP3 requires external bias voltages for operation. The GM-MCP3-1000, which outputs a 1000V gate pulse, provides the highest level of signal suppression for the most demanding applications.
