摘要
本文着重介绍在“神光”装置上两路对打黑洞靶辐射特性实验研究。利用两台配置时标装置的亚千电子伏能谱仪(Dante)进行时间关联测量,分别监测双束靶吸收转换区和内爆压缩区泄漏X光谱脉冲波形、辐射能谱、辐射温度、辐射时间谱及其辐射温度随时间变化关系。同时进行了大量不同型号黑洞靶实验,给出吸收转换区辐射温度随注入激光能量面密度变化的关系曲线及其定标关系式。实验中,首次把掠入射平面反射镜用于亚千X光能谱测量,并取得预想的结果。
Experiments to study radiation properties of Hohlraum targets with two laser beam illumination from both sides are described. Two sub-keV X-ray spectrometers with time correlation were used to measure X-ray spectra of the conversion region and the implosion region, respectively. The X-ray spectra, radiation temperature, X-ray time spectrum and the relation of temperature with time were obtained. At the same time, many shots with different types of Hohlraum were taken to study the relation of radiation temperature in the conversion region with input laser power density. One of the spectrometer channels was installed with a grazing incidence reflection mirror which gave nice results.
