Abstract
In an electron beam device having a cathode (1), in which a high-power electron beam propagating along a beam axis (5) is generated, an anode (3) arranged behind the cathode (1) in the direction of beam axis (5), and a collector (4), arranged behind the anode (3) in the direction of the beam axis (5), for decelerating the electrons of the electron beam, the collector (4) is constructed of several collector stages (6) which are arranged successively in the direction of the beam axis (5) and which successively decrease in potential. A high-voltage direct-current supply (13), which consists of a series of similar switching stages (S1, . . . , S6) which are in each case constructed as switchable medium-voltage sources and the outputs of which are connected in series, is provided for the feed arrangement. The potentials of the collector stages (6) are provided by corresponding taps between the switching stages (S1, . . . , S6) of the high-voltage direct-current supply (13 ).
