摘要: 为开展L波段低阻无箔渡越辐射高功率微波发生器的单次实验，设计了一种满足需要的电容器储能脉冲磁场系统。系统储能电容5.4 mF，设计的螺线管线圈长45 cm，其理论电感和电阻值分别为42 mH和0.66 。基于该设计，绕制了磁场线圈并搭建了实验平台，线圈实际电感和电阻值分别为40 mH和0.61 。目击靶实验进一步证实了励磁系统产生的导引磁场能够较好地约束电子束。Abstract: The guiding magnetic field system is designed to conduct the experimental investigation of the L-band low-impedance foilless transit-radiation oscillator. The total capacitance of the system is 5.4 mF. The length of the designed solenoid is 45 cm, and its theoretical inductance and impedance are 42 mH and 0.66 respectively. Based on the design, the coil is fabricated and the corresponding platform for the experiment is established. The real inductance and impedance are 40 mH and 0.61 respectively. The target experiment testifies that the intense relativistic electron beam can be well guided by the designed magnetic field system.
