Figure 2: Schematic sketch on voltage ramping during “Start-Up” procedure.
Note
The detector starting operation voltage for “MCP-B” is given in the specification sheet.
Example:
The “MCP-B” voltage is given in respect to the “MCP-F” voltage. A ramp time of 4min. should be
used to change the “MCP-B” voltage from 0 V to a target voltage of exe1600V.
4.1.2 Dark Count Rate Measurement
• Check the detector output by means of any electronics and software or with an oscilloscope where the
input is terminated with 50Ohms.
• The dark count rate without any source should be as given in the specification sheet.
4.1.3 Standard Detector Measurement
• After finishing the dark count rate measurement with a satisfying result, you may now start carefully
with an electron or light source observing the detector output.
Turn off the high voltage before performing any changes of the cabling.
