辐射温度的数据处理方法
Data processing method for radiation temperature
-
摘要: 辐射温度是间接驱动惯性约束聚变实验中可以定量测量的重要物理量。引进了一种通过直接计算辐射通量来得到辐射温度的方法，该方法的主要优点是计算简单，避免了某些时刻不能计算辐射温度的情况。由该方法得到的辐射温度与传统方法计算结果符合较好，不确定度均为7%。通过与冲击波测量温度峰值的结果对比确认了数据处理方法的正确性。在此基础上建立了国内某大型激光装置上的新型15道软X光能谱仪的数据处理系统。Abstract: Radiation temperature could be quantified in indirect-drive ICF experiments. This paper introduces a new method for calculating radiation temperature without unfolding. It is a simple method which can provide the real time temperature. Radiation temperature obtained by this method is in accordance with that calculated by traditional methods with an uncertainty of about 7%. The result by measuring shock wave’s velocity has proved this method to be correct. With this method, we have built a new data processing system for 15-channel soft X-ray spectrometer.
