Generation of gigawatt level beat waves

Abstract

The initial experimental results of generating gigawatt level beat waves with two microwave sources are presented. The detailed measures for enhancing the power handling capacities of the applied devices are explained. In the experiments, the operation frequencies of the microwave sources are 9.41 GHz and 9.59 GHz, respectively. The microwave sources are driven by a single accelerator capable of producing dual electron beams to make sure that they are operating simultaneously. The beat frequencies, measured by the oscilloscope directly, are about 180 MHz, and the peak powers of the pulsed beat waves are about 4.3 GW with durations of about 40 ns.
