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360eV,Fe的平均电离度为18.8。
In Thomson scattering experiment on SG-Ⅱlaser 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.
