1-Channel MCP Detector MCPD25 Manual | Surface Concept GmbH
3.2.2 Cabling and High Voltage
The general connection scheme of the MCP detector is shown in in
Figure 1: Connection scheme of the MCPD25.
• The detector holds two SHV connectors for the high voltage supply named “MCP-B” and “MCP-F”. The
naming can be found directly engraved on the flange. “MCP-F” is the contact to the front side of the
MCP stack, “MCP-B” is the contact of the detector anode and of the back side of the MCP stack via an
internal resistor.
• Signal readout is realized via a single, 50Ohm matched BNC feedthrough named “SIG”. The naming can
be found again directly engraved on the flange.
Be sure that all voltages are settled to zero before connecting the high voltage cables to
the detector, otherwise serious damage to the detector can occur due to high voltage
sparks.
The detector should be kept under vacuum all the time.
The best long term storage environment is an oil free vacuum in the 1E-2mbar range or
better. The transport container is not designed for a long term storage of the detector. A
storage time of one month should not be exceeded.
The transport housing should be evacuated regularly with a period of at least one month,
in case that the transport housing must be used for a longer storage time.
