Pre-Acquisition Setup - Image Intensier
5.4.3 - MCP Gain
The gain of the Micro-Channel Plate (MCP) in the image intensier can be varied through software from a setting of 0 to
4,095. By increasing the gain, the voltage across the MCP is increased and hence the signal reaching the CCD sensor is
amplied. The value can be entered in the MCP Gain text box of the Setup Gating tab of the Setup Acquisition dialog
box. It can also be selected on the Run time control dialog box, e.g.:
The graph below shows typically how the signal level on the CCD sensor varies with increasing gain setting.
Note: MCP gain versus DAC settings is reported for each system on the associated performance sheet.
