A novel v-band support rod helical slow-wave system （SWS） is proposed in this paper.The high frequency properties of the novel SWS are calculated by using electromagnetic software HFSS and are compared with the traditional SWS.The influence on the high frequency properties of the novel SWS is analyzed for different dimension parameters of metal pieces in support rods.The beam-wave interaction is simulated by 2.5-D large-sigal interaction code.The calculations indicate that the novel SWS TWT with the best dimension of metal pieces can produce output power over 60 W with the gain over 54 dB and the electronic efficiency over 8％ ranging from 56 to 64 GHz at a cathode voltage of 9.3 kV and a beam current of 75 mA.
