Abstract :
A high power millimeter wave source is proposed in this paper. This device, which can be operated at a relatively low magnetic field, mainly includes two sections of slow-wave structure (SWS) separated by a drift tube, an output cavity, and a tapered waveguide. Its physical process is investigated by theoretical analysis and PIC simulation, and the results agree well with each other. Its guiding magnetic field can be lowered as its output power and efficiency be increased after optimization. A typical simulation result is that, with the beam parameters of 600 keV and 5.1 kA, and magnetic field of 0.8 T, an 8 mm microwave with output power near 1 GW is generated, and the conversion efficiency is over 25%.
