0.35μm激光与金靶耦合发射X光能谱分析
-
摘要: 利用改进后的More模型计算Au等离子体各电离度离子的Einstein系数和线发射强度。在0.35μm激光与金平面靶耦合产生晕区等离子体条件下,求解离子模型定态速率方程组得到离子布居概率,从而求出X光线发射能谱。将此能谱与JB19程序计算得到的出系统外边界光子能谱进行了比较。Abstract: The Einstein coefficients and line-emission intensities of Au ions are calculated with an improved More model. The population of the ions and the X-ray emission spectrum are given by solving stationary H-like ion-model rate-equations for the corona plasma produced by coupling of laser with Au target. The spectrum is compared with the photon that obtained by multi-group photon diffusion code JB19 simulation.
