Development of a 0.33THz pulse gyrotron

A 0.33THz pulse gyrotron is currently under development at Peking University, which is predicted to generate coherent broadband radiation in each pulse. The pulse gyrotron is designed based on the fundamental harmonic co-rotating TE₆₂₊⁽¹⁾ mode. The scheme of tuning magnetic field on backward-wave interaction is adopted to realize broadband radiation. The compact pulse gyrotron is promising in the applications of coherent imaging and detection in the medical science and industry.
