Abstract
One possibility for increasing the efficiency of relativistic gyrodevices is to trap a significant portion of the electrons at the entrance to the interaction space, then profile the external magnetic field to maintain cyclotron resonance between the decelerating electrons and the wave.1 The overall efficiency of such a configuration is given roughly by the product of two terms: the efficiency of trapped particles, ritrapped, and the fraction of trapped particles, f i trapped: 71 = Ytrapped X ftrapped• The fraction of trapped particles, f , trapped 7 depends strongly on velocity spread, and generally this dependence must be found numerically. The efficiency of trapped particles, on the other hand, is approximately equal to the maximum single particle efficiency, rasp, given bye
