Abstract
Experimental results are presented of the first cyclotron autoresonanc e maser oscillator operated using the second harmonic of the cyclotron frequency. An interaction efficiency of 3.9% has been measured at a f requency of 14.27 GHz, using an 80 ns pulsed, 14 A electron beam of en ergy 300 keV, to produce a coherent microwave power of 170 kW. Emissio n occurred at 3.7 times the relativistic cyclotron frequency, due to t he large Doppler frequency increase and second harmonic interaction.
