| Abstract: | The folded waveguide, the electron optical system, input and output windows of the 0.14 THz folded waveguide traveling-wave tubes were designed and simulated with the help of HFSS and CST. The beam wave interaction was also simulated. Research on development of 0.14 THz TWTs was done, including fabrication and welding of the folded waveguide slow wave structure and hot test experiment. In the condition of voltage 15.4 kV, the maximum saturated output power was 8.3 W and the output frequency was 140.8 GHz. The maximum gain was 28 dB and maximum power bandwidth was 2.9 GHz. |
