| 摘 要： | 针对实验室等离子体的辐射物理条件和等离子体箍缩三温的数值模型,提出一种定量计算Z箍缩等离子体辐射能谱的近似方法。在给出计算能谱结构的理论方法之后,再将这种近似计算方法编入到Kr喷气Z箍缩等离子体X射线辐射的二维三温辐射磁流体力学模型中,得出典型Kr喷气Z箍缩X射线辐射的能谱分布。对照"强光一号"加速器Kr喷气箍缩实验测量得到的辐射能谱分布,分析了理论与实测结果之间存在的偏差。

| Abstract: | With the laboratory plasmas radiation and a three-temperature plasma model for Z-pinch,an approximate prediction of the radiation spectrum from Z-pinch is proposed.The mathematical method is incorporated into a two-dimensional,three-temperature radiation magneto-hydrodynamics model for the simulation of the krypton gas-puff Z-pinch,and the energy spectra has been obtained.In comparison with the experimental results on "Qiangguang-I" accelerator,the differences between the predicted and the experimental data are analyzed. |
