Experiment of 0.34 THz relativistic backward-wave oscillator

The design of 0.34THz relativistic backward-wave oscillator (RBWO) is presented in this paper. The sine slow-wave structure has been fabricated successfully though technical study. The measurement methods of pulse width, frequency, and power for the nanosecond, high-power, THz signal have been studied. In the experiment the RBWO produced THz radiation with power 600kW, frequency in the range of 0.32THz~0.36THz, pulse width 1.66ns, and it could operate at the pulse repetitive frequency 10Hz.
