摘要
确定了影响辐射温度测量的软X光能谱仪各种光学元件、电子器件的不确定度及还原算法等不确定度来源。建立了基于蒙特卡罗随机采样的不确定度分析方法,获得了各种不确定度综合影响下的辐射温度不确定度。通过单独对谱仪各个探测通道时间对齐进行的分析,显示这一因素对辐射温度不确定度有较大影响。
Abstract
Soft-X-ray spectrometers are used in diagnosis of the equivalent radiation temperature of hohlraum in indirectly driven inertial confinement fusion experiments. Uncertainties of the soft-X-ray optical elements and electronic devices of the spectrometer, and the recovery methods are determined, which influence the measurement of the radiation temperature. The uncertainty analysis method based on Monte-Carlo sampling is implemented and uncertainty of the radiation temperature including all kinds of uncertainty factors is obtained. The alignment of signals from different detection channels of the multi-channel spectrometer is analyzed separately, which proves to be a large uncertainty source.
