摘    要:
介绍了用国内1ns长脉冲和国外多脉冲驱动的类氖锗的实验数据检验X光激光的理论模拟程序系列的工作。在长脉冲驱动时,对波长19.6,23.2和23.6nm三条激光线,理论模拟与实验数据基本符合。在多个短脉冲驱动时,除了与严重过电离的复合等离子体有关的实验外,理论模拟与实验也基本符合。为今后设计激光聚变等离子体诊断所需类氖锗X光激光光源工作打下了基础。

关 键 词:类氖锗   X光激光   电子碰撞激发机制   亚稳态   数值模拟

Abstract:
In order to test X ray laser (XRL) series programs, simulations of some experiments of Ne like Ge XRL were completed, including domestic experiments driven with long pulse (1ns) and international experiments driven with multiple-pulse. In the case of long pulse, for three lines of 19.6, 23.2, 23.6nm, theoretical results are mainly consistent with experimental data. And in the case of multiple pulse, theoretical simulations are also consistent with experiments except the experiments with seriously over ionized recombination plasmas. This work has laid the foundation of later effort to design Ne like Ge XRL resource which is used to diagnose plasma of ICF.
Keywords:ne like ge  x ray laser (xrl)  electron collisional excitation scheme  quasi steady state(qss)  simulation
