【摘要】 采用数值模拟与实验测量相结合的方法,完成了探测系统刻度,得到了该探测器对单能光子的能量全响应函数,在此基础上探索出改进的剥谱法,对测量得到的连续硬X射线能谱进行解析,扣除了测量谱中非光电效应对每道计数的贡献,复现了测量位置处的实际能谱,并对该能谱测量方法进行了误差分析,提出了进一步完善措施。更多还原

【Abstract】 The method of spectrum unfolded was studied and applied to correct continuous hard X-ray measurement spectrum on the base of energy respond function of single-energy photon and relative effi- ciency curve for the HPGe detector which had been got by simulated calculation and measurement,the in- fluence of counts for each channels coming from nophotoelectric effect has been avoided in the measure- ment spectrum.The reality spectrum was rebuilt and the improve measures of precision for this measure- ment method of spectrum were advanced by error analyse.更多还原
