Abstract
A switch which reduces the voltage between the photocathode and the first dynode in the activated switching state compared to the deactivated switching state and a control unit which is adapted to move a target spot, which can be illuminated by means of the light source, over a scanning field by means of a deflecting unit. The control unit activates the switch when the target spot enters a given region of the scanning field and deactivates the switch when the target spot exits the region.
