Abstract
Various crossed-field amplifiers (CFAs) are disclosed herein. In one embodiment, the geometry of the cathode and/or the anode reduces the velocity of the electrons as they travel near the anode drift block to increase the distribution of the electrons in the drift gap. In another embodiment, an abrupt geometric change to the cathode at the beginning or the end of the anode drift block can disperse the electrons, thereby increasing the rate of mixing and diffusion. By increasing the distribution of the electrons, the peak amplitude of spurious emissions produced by a CFA can be reduced.
