Generating Sub-Terahertz Chaotic Radiation in a High-Current Relativistic Gyrotron in the Mode of Frequency Multiplication
It is shown that for a high-current relativistic Ka-band gyrotron operating in the chaotic generation mode on the lowest mode of a circular waveguide TE1,1, effective radiation is possible at the seventh harmonic of the gyrofrequency on the TE7,2 mode. The relative width of the spectrum of chaotic sub terahertz radiation can exceed 5% at a megawatt output power level.
