[Abstract]:In order to meet the special requirements of femtosecond imaging tube scanning camera for deflector, a traveling wave deflector applied to high speed scanning camera is designed.According to the design theory of traveling wave deflector of Finch, the design flow is simplified and the model of deflector is established by using HFSS software. The characteristics of high frequency signal propagation and bandwidth of traveling wave deflector are simulated and solved.The basic structure parameters of traveling wave deflector are determined by matching the phase velocity of electromagnetic wave and the flying velocity of electron beam, and a traveling wave deflector suitable for high-speed scanning camera with 10kV electron energy is optimized and designed.The designed traveling wave deflector is 44mm in length, 4mm in plate spacing, 4GHz in bandwidth and 119.8mm / kV in deflection sensitivity.The test results of the traveling wave deflector based on the existing high-speed scanning camera show that the design results are accurate and reliable, and the design method is appropriate.The research provides an effective way for the design of traveling wave deflector of VTR and shortens the research and development period of high time resolution scanning camera.
