Design and experiment of 0.13THz folded-waveguide oscillator

This paper shows the design and experiment results of the 0.13THz folded-waveguide oscillator. The folded-waveguide structure has been manufactured successfully though CNC machining. The initial tube has been fabricated and tested. According the experiment, The initial tube gets the maximum continuous output power about 6W at 0.13THz from a 15.6 kV, 29 mA electron beam. The electric tunable bandwidth is only about 1GHz in the range of 0.129THz ~ 0.13THz, by the reason of the electron-optical system.
