Abstract
A mildly relativistic electron beam (500keV, 200A,10ns) injected into an X-band rectangular waveguide immersed in a uniform axial magnetic f ield (4-10kG) produced magnetically tunable microwave radiation in the 9-13 GHz frequency range with an estimated output power of 1MW. The f requency range and tunability of the radiated microwave agreed with a theoretical model for a gyrotron backward wave oscillator taking into account the low energy component of the beam electron.
