用类氖锗X光激光实验检验理论模拟
Test of simulation by experiments of Nelike Ge Xray lasers

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。Abstract: In order to test Xray laser (XRL) series programs, simulations of some experiments of Nelike Ge XRL were completed, including domestic experiments driven with longpulse (1ns) and international experiments driven with multiple-pulse. In the case of longpulse, for three lines of 19.6, 23.2, 23.6nm, theoretical results are mainly consistent with experimental data. And in the case of multiplepulse, theoretical simulations are also consistent with experiments except the experiments with seriously overionized recombination plasmas. This work has laid the foundation of later effort to design Nelike Ge XRL resource which is used to diagnose plasma of ICF.
