System Development and Perfomance Evaluation of a 0.272 THz Pulsed Folded Waveguide Traveling Wave Tube Oscillator

We present recent experimental results of a 0.272 THz energy-recirculating folded-waveguide traveling wave tube oscillator, developed in Ulsan National Institute of Science and Technology (UNIST), South Korea. Main components of the device were designed, fabricated, and evaluated individually. The 11 kV and 92 mA electron-beam from the scandate cathode is guided by a solenoidal magnet system and the electron transmission rate is monitored. The generated signal from the device is analyzed by a developed plasmonic THz detector and a heterodyne system. The details will be provided in the paper.
