A prototype 0.22 THz Folded Waveguide Traveling Wave Tube(FWTWT) is designed and studied by experiments. By the comparison between the experimental and simulated results, this 0.22 THz FWTWT is optimized and improved. The loss characteristics, Slow Wave Structure(SWS) dimension adjustment and the issues of manufacturing SWS are also studied. HFSS is adopted to study SWS parameters and a large-signal software is used to simulate its amplification. The results of 100 mW power output and 5 GHz of 3 dB bandwidth are obtained in this new design.
