摘要: 提出了一种包含内外筒、细线径、多起端密绕的螺旋脉冲形成线(PFL)结构，与Tesla变压器有机组合，构建了长脉冲产生装置，可以实现较高的能量效率，并且结构紧凑，适于重复频率工作。以最大充电电压为结构设计原则，螺旋PFL波阻抗为12.6倍慢波系数，且形成线纵横比大于3.1时，Tesla变压器的耦合度能达到0.95；以形成线最大储能为结构设计原则，螺旋PFL波阻抗为7.5倍慢波系数，且形成线纵横比大于2.0时，Tesla变压器的耦合度能达到0.95。实验结果与理论分析吻合得较好。Abstract: A spiral pulse forming line was presented, which consisted of inner cylinder and outer cylinder, and was densely wound by thin lines with multiple origins. Combining it with Tesla transformer, a compact long pulse generator was constructed, which had high energy efficiency, compact structure, and could work at repetitive rate. On the design principle of maximizing charging voltage, the impedance value of the forming line would be 12.6 times the slow wave coefficient, and high coupling coefficient 0.95 of Tesla transformer would be obtained when the aspect ratio of the line was greater than 3.1. On the design principle of maximizing stored energy, the impedance value of the line would be 7.5 times the slow wave coefficient, and high coupling coefficient 0.95 of Tesla transformer would be ob
