ABSTRACT:
A vacuum chamber is provided with an electron emission source on a first side wall, a collector on a second side wall opposite to the first side, and an insulated electrode on a bottom wall. Electrons emitted from the electron emission source move over the insulated electrode to be collected by the collector, so that the spatial position and the path of the electrons on the insulated electrode are controlled dependent on an electric potential generated by the insulated electrode.
