Abstract :
Experimental results from a study of a nonadiabatic pumped second-harmonic gyrotron oscillator are reported. A steady second-harmonic cavity emission has been observed at 28 GHz and for the TE/sub 02/ waveguide mode. A peak power of approximately 25 MW has been reached with approximately 9% efficiency. The magnetic field in the pumping section region is modeled, and beam pumping is simulated.<>
