| 摘 要： | 喷气Z箍缩的负载参数（如质量线密度及半径）必须和脉冲驱动源的电流（幅值和上升时间）相匹配。作者利用微型快速电离规测量了喷气Z箍缩中超音速喷嘴产生的气体负载的密度分布，并由此得到了负载质量线密度为43μg/cm，这符合原定的喷嘴设计指标。

| Abstract: | For a particular pulsed-power generator, i.e.with, fixed pinch current as well as its rise time, the Z-pinch load (initial radius r 0 and line mass density m 0 ) should be optimized to maximize the X-radiation. The radial density profile of the gas load produced by a supersonic nozzle used in gas puff z-pinch was measured with a miniature fast ionization gauge and it yields a line mass density of 43 μg/cm meets the requirement of the nozzle design. |
