First bandwidth measurements of a novel gyrotron amplifier are presented. The coupling between the second harmonic cyclotron mode of a gyrating electron beam and the radiation field occurred in the region of near infinite phase velocity over a broad bandwidth by using a cylindrical waveguide with a helical corrugation on its internal surface. With a beam energy of 185 keV, the amplifier achieved a a maximum output power of 1.1 MW, saturated gain of 37 dB, linear gain of 37 dB, saturated bandwidth of 8.4 to 10.4 GHz (21% relative bandwidth), and an efficiency of 29%, in good agreement with theory.
