5 MCP Detector Layout
5.1 MCP Detector - Vacuum Wiring
The MCP detector MCPD25 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 detector anode from the high voltage of the MCP stack as well as to couple pulses from the electron
cloud into the metal anode.
Figure 4: Layout of the HV and signal connections.
The base flange of the MCP detector carries two single SHV feedthroughs for the high voltage supply of
the detector and a single BNC feedthroughs for signal transfer (see
Figure 4
).
5.2 MCP Detector - Connection Ports
The naming of the SHV connections are engraved directly on the flange. The internal high voltage
connection for the detector is given schematically in
Figure 5.
