ABSTRACT:
An electron multiplier which is formed by at least two microchannel plates which are arranged one above the other and which operate in the saturation mode.
The second microchannel plate produces an output charge for each incident electron which depends on the electrical field in the vicinity of the input surface of said second plate. By suitable geometrical structure in the plate or by shaping the potential applied thereto, an electrical field is produced which varies from point to point on its input surface. The charge output thus contains information regarding the location of the incident electron.
