潘尼管是利用电子在高频结构中的位置选择机制实现注波净能量交换的回旋器件,具有高效率与低磁场的显著特点。本文在简述其基本原理的基础上,研究了其设计理论与方法,进行了相应的数值计算,设计了一只8 mm波段三次回旋谐波潘尼管:采用4开槽渐变到圆波导的开放式谐振腔高频结构,2π工作模式,束电压43.5 kV,束电流1.45 A,最后采用3D-PIC模拟软件进行验证、优化。模拟结果显示,该器件可获得37.8 kW平均输出功率,器件效率可达到60%,展示了其作为高效永磁包装器件的良好应用前景。
Penny tube is the use of electronic structure in the high-frequency position selection mechanism to achieve the net energy exchange wave injection device, with high efficiency and low magnetic field of the salient features. Based on the basic principle of this method, the design theory and method are studied. Corresponding numerical calculations are carried out. An 8-nm triple-harmonic harmonic Penny tube is designed: Open-cavity high-frequency structure, 2π mode, beam voltage of 43.5 kV, beam current of 1.45 A, and finally using 3D-PIC simulation software to verify and optimize. Simulation results show that the device can achieve an average output power of 37.8 kW, the device efficiency can reach 60%, demonstrating its good application prospects as a highly efficient permanent magnet packaging device.
