摘要：
We present the results of the theoretical and experimental studies, which are aimed at developing pulsed gyrotrons with relativistic electron beams operating in the millimeter-wavelength range and retaining the multimegawatt power level. The use of the interaction at the second gyrofrequency harmonic, which is characterized by a sufficiently high efficiency and availability of the solution for the mode selection problem, allows one to double the generation frequency without increasing the magnetic field. In the corresponding experiment, the output radiation power exceeded 2 MW, and the efficiency was about 30% at a wavelength of 5.5 mm.
