Abstract

The present invention relates to a coaxial vircator where the cathode is arranged relative the anode in such a way that it is allowed to rotate around its own and the anodes cylindrical axis. In further embodiments are only parts of the cathode surface covered with an emitting material which leads to an angular dependence between the emitting cover and the anode. Alternatively, or as a complement, the anode and the cathode could be given asymmetrically arranged symmetry axes. This leads to a varying distance between the anodes midpoint and the cathodes midpoint.
