Abstract
Experimental results of the first efficient operation of a long-pulse cyclotron autoresonance maser oscillator are presented. Output power o f 1.9 MW for a beam energy of 450 keV and current of 80 A, correspondi ng to an efficiency of 5.2%, has been measured at 27.8 GHz in the TE11 mode of a Bragg resonator. The observed frequency of the cyclotron au toresonance maser emission corresponds to a Doppler upshifted frequenc y of 2.9 times the relativistic cyclotron frequency. A significant mod e competition between the TE11 and a TM01 mode is present.
