摘要
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.
Electron temperature is very important for understanding of physical processes on energy absorption and transport in laser produced plasma. Experiments were conducted on XingGuang Ⅱ high power laser facility. A spatially resolved crystal spectrometer was used to measure the aluminum line radiation. By comparison of measured spatially resolved aluminum line radiation with calculated ones with coronal equilibrium, spatially resolved electron temperature of aluminum plane target was obtained.
