MCP (microchannel plate)

F1217-01

MCPs are made of millions to tens of millions of conductive glass capillaries bundled together to form a thin plate. Each of these capillaries (channels) acts as an independent secondary elect ron multiplier, forming a two-dimensional electron multiplier. 

F1217-01 is a circular MCP with an effective area of Φ 42.0 mm.

*1: Strip current is the current that flows through channel walls when a voltage is applied between MCP IN and OUT. It is given by dividing the applied voltage by the MCP resistance.

*2: Supply voltage: 1.0 kV, vacuum: 1.3 × 10-4 Pa, operating ambient temperature: +25 °C

*3: Vacuum: 1.3 × 10-4 Pa

*4: Resistance-match means that resistance values of MCPs are to be matched when they are used in two stages.
