摘要

To develop compact, reliable and high power terahertz (THz) radiation sources, experimental investigation of the operation at a second harmonic THz gyrotron oscillator is reported in this paper. During operation in five microseconds pulse length regime with 41kV beam voltage and 1A beam current, the instrument generates over 1 kilowatt of power in the second harmonic TE26 mode at 0.423THz. And the designs of the gyrotron operation agree with the experimentally measured output power and Radio-frequency (RF) efficiency. Details of the gyrotron design, operation and measurements of output radiation are given.
