| 摘 要： | 在神光Ⅱ激光装置上，利用激光加热金腔产生的X射线辐射场加热Fe/Al样品，随后用激光探针光入射Fe/Al等离子体并在90散射方向采集散射光谱，同时也记录下了样品的自发辐射光谱。实验观察到了清晰的散射光谱以及Fe等离子体自发辐射光谱，诊断结果表明，Fe/Al等离子体的平均电子温度为360 eV，Fe的平均电离度为18.8。

| Abstract: | In Thomson scattering experiment on SG-Ⅱ laser facility, X-ray radiation produced by laser interaction with Au hohlraum was used to heat the Fe/Al sample. The scattering spectra of the probe laser beam were measured at 90. The self-emission from the sample plasma was also recorded. Analyzing and fitting these two spectra, the average electron temperature was 360 eV, and the ionization degree of Fe was 18.8. |
