Abstract

The regime of excitation of subnanosecond high-power microwave pulses has been studied in a relativistic Ka-band BWO, using an electron beam from a compact, pulsed high-current electron accelerator (290 keV, 2.3 kA, 1 ns). We determined the conditions when the power conversion factor can reach up to 1.5 at an output pulse power of 1.2 GW and a pulse width of 200 ps.
