利用“星光”激光装置的线聚焦激光束辐照碳铝组合靶，形成Ｘ光点源及铝等离子体的衰减区。用带时间分辨的平场光栅谱仪测量由碳等离子体发射的Ｘ射线在穿过长为３ｍｍ的铝等离子体后强度随时间的变化。测量结果表明该方法用于激光等离子体衰减系数测量是可行的。
A linear focusing laser beam of a “Starlight” laser device is used to irradiate the carbon-aluminum composite target to form an X-ray source and an attenuation region of the aluminum plasma. The intensity of the X-rays emitted from the carbon plasma with time after passing through an aluminum plasma of 3 mm in length was measured with a time-resolved flat-field grating spectrometer. The measurement results show that this method is feasible for laser plasma attenuation coefficient measurement.
