电子温度是ICF研究中最基本的物理参数,对于了解激光吸收、X光转换和辐射输运等物理过程有着重要的物理意义。在星光Ⅱ装置(0.35μm,70J,700ps)上,采用空间分辨晶体谱仪从发泡铝平面靶切向方向观测,测得了铝平面靶沿激光轴向方向发射的空间分辨线谱,理论上采用日冕模型计算,二者配合给出了铝靶电子温度空间分布0.4keV～1.4keV Electron temperature is the most basic physical parameter in ICF research and has important physical meaning for understanding physical processes such as laser absorption, X-ray conversion and radiation transport. Spatially resolved crystal spectrometer was used to observe the tangential direction of the aluminum flat target in the direction of the laser axial direction in the Star Ⅱ device (0.35μm, 70J, 700ps). Theoretically, Using coronal model calculation, the two are given with the aluminum target electron temperature spatial distribution 0.4keV ~ 1.4keV
