5 MCP Detector Layout
5.1 MCPD40 - Vacuum Wiring
The MCP detector MCPD40 consist of a detection area, defined by the MCP holders and the detector anode.
The front side of the detector anode is on high voltage potential, while the signal readout is realized close
to ground potential (in respect to the high voltage of the MCPs). A pulse coupling layer is used to isolate
the high voltage from the ground potential within a “sandwich” layer system of the detector anode.

detector elements.
The internal connection of the high voltage for MCPD40 R006 is given schematically in
.

Note
The resistance between “MCP-F” and “MCP-B” (resistance of MCP stack and internal resistor)
should be in the range of 100 – 400MΩ (the exact values are given in the specification
sheet of the detector). The resistance between “MCP-F” and “SIG” and“MCP-B” and “SIG”
should be unlimited.
