Fiducial system for the diagnosis of temporal evolution of radiation fluxes with soft-X-ray spectrometer in inertial confinement fusion experiments

摘要: 介绍了时标系统的构成、原理和数据处理方法,并对时间关联的不确定度进行了分析.该时标系统成功将软X射线能谱仪自身多个探测通道的信号以及三台不同位置处的谱仪的时间信号关联起来,关联精度约为70ps.在神光Ⅲ原型激光装置上进行的实验中用软X射线能谱仪从不同方向测得辐射源和辐射输运管末端口辐射能流随时间的演化曲线,反映了输运管内热波沿轴向传输以及软X射线辐射流衰减的物理过程.

Abstract: In inertial confinement fusion experiments,a fiducial system is established in order to correlate the signals from different channels of one spectrometer and the signals from different spectrometers to obtain time-related experimental data.The constitution,the principle and the data processing method,together with the uncertainty analysis are introduced.Signals from different channels and from three spectrometers diagnosing from different directions are correlated with an uncertainty of 70 ps.The time-related historical radiation fluxes from a cylinder target,measured from three different directions,are obtained in the experiments on Shenguang II prototype laser facility,offering the physical information about the heat wave propagation along the axis of the cylinder and the attenuation of soft X-ray radiation flux.
