What is the maximum operating voltage of a microchannelplate?
A.-The operating voltage is defined as a potential difference between the input side and output side of a microchannelplate. It is dependent on the length-to-diameter ratio(L/D) of a microchannelplate. The rule of thumb is that multiplying the L/D ratio by 25 will give the maximum operating voltage. For example, the maximum operating voltage for a 40:1 L/D MCP is Vmax=40×25=1,000 volts.
