5.4.4 - Insertion Delay
Insertion delay refers to the propagation delay of a trigger source (External Trigger, Internal Trigger (Fire pulse) or Direct
Gate) to travel through the electronics and open the image intensier. A radio button allows the user to select between
‘Normal’ and ‘Ultra Fast’ options. Switching from ‘Ultra Fast’ to ‘Normal’ adds 100 ns delay to the gate pulse. This
allows the MCP voltage to rise and settle when using Intelligate before opening the photocathode. Intelligate is not
available when using ‘Ultra Fast’ insertion delay.
