On the limiting admissible power level of pulsed microwave generators based on high-current electron accelerators

At present, various powerful microwave devices capable of generating microwave pulses of nanosecond duration and with a power of several gigawatts are constructed on the basis of high-current electron accelerators with energy on the order of several megaelectronvolts. These generators are on major interest for high-resolution radio detecting and ranging, designing charged-particle accelerators of super-high energies. and for solving a number of problems of pulsed microwave power engineering. For all these regions of application of the microwave technique, one of the important problems is increasing the pulsed power. A goal of the present study is to determine the maximum microwave power that can be generated in a certain relativistic microwave generator and to clarify the dependence of the power an both parameters of high-current electron accelerators used and the type of a microwave generator
