Abstract
An apparatus is provided for generating accelerated electrons, including a housing; an inlet for supplying a working gas; at least one first cathode; and at least one first anode, between which a corona discharge plasma can be generated. Ions from the corona discharge plasma can be accelerated onto the surface of a second cathode. Electrons emitted by the second cathode can be accelerated in the direction of the electron exit window by means of a second electric voltage applied between the second cathode and a second anode. The housing, the second cathode, and the electron exit window are ring-shaped. The ring-shaped space is divided into ring segments. Each ring segment has at least one wire-shaped electrode, which extends through the ring segment. At least one separate power supply device is associated with each ring segment, by means of which the strength of the electrical current is adjustable.
