| 摘 要： | 分析了电流爬升阶段等离子体密度和电流爬升率对逃逸电子行为的影响，研究了低杂波辅助电流驱动条件下的逃逸电子辐射行为。结果发现:电流爬升阶段等离子体密度的大小严重影响了电流爬升阶段甚至电流平顶阶段逃逸电子的行为，较低的等离子体密度将会导致放电过程中比较强的逃逸电子辐射；低能逃逸电子辐射随着电流爬升率的增大而增强；低杂波辅助电流爬升可以有效地节约装置的伏秒数；降低放电过程中的环电压，可有效抑制逃逸电子的产生。

| Abstract: | Approximate series solutions of the output pulse waveforms and transmission efficiencies of transmission line with exponential impedance profile have been developed based on distributed-parameter model for typical incident pulses suitable for next generation of Z-pinch plasma drivers.The transmission efficiencies are studied computationally with these solutions for petawatt-class Z-pinch driver's exponential transmission line taking account of the line's length and ratio of output impedance to the input as ... |
