摘要:

提出了一种基于物理动机的函数,用于精确确定电磁量能器中的总吸收峰,并克服了许多常用方法中存在的偏差。该函数是探测器分辨率函数与δ函数和尾函数之和的卷积,δ函数表示能量的完全吸收,尾函数描述能量的部分吸收,并取决于探测器材料和结构。通过对三种典型情况的仿真,验证了该方法的有效性.相对于Crystal Ball函数,提取的峰值、分离度和峰面积的准确度平均提高了一个数量级。

英文摘要:

A physically-motivated function was developed to accurately determine the total absorption peak in an electromagnetic calorimeter and to overcome biases present in many commonly used methods. The function is the convolution of a detector resolution function with the sum of a delta function, which represents the complete absorption of energy, and a tail function, which describes the partial absorption of energy and depends on the detector materials and structures. Its performance was tested with the simulation of three typical cases. The accuracy of the extracted peak value, resolution, and peak area was improved by an order of magnitude on average, relative to the Crystal Ball function.
