| 摘 要： | 设计了一个用于为L波段同轴相对论返波振荡器提供导引磁场的双线绕制、分段磁场线圈系统。根据粒子模拟中对磁场的要求和实验室已有的条件来确定磁场的各参数,通过数学软件Mathcad和全电磁粒子模拟程序Karat对设计出的轴向磁场位形进行验证。采用基于Hall效应的Tesla计对加工好的磁场线圈产生轴向磁场空间分布进行了测量,同时利用电子束轰击尼龙靶来考察电子束被导引的效果。利用绕制好的磁场线圈开展了初步实验研究,在二极管电压655kV,电子束流为10.4kA,导引磁场0.7T的条件下,输出微波峰值功率约为864MW,微波波形半高宽为23ns,功率转换效率约为12.7%,频率1.61GHz。

| Abstract: | A solenoid using the double winding technique has been designed to drive a coaxial relativistic backward wave oscillator(RBWO). First, the solenoid parameters were chosen by the particle simulation and practical applications. In addition, the magnetic field distribution was validated by numerical calculations with the Mathcad code and the particle-in-cell(PIC) Karat code. Then the profile of the axial magnetic field distribution was measured by a Tesla-meter based on the Hall effect, and the guiding effect ... |
