本文提出了一种计算在横向分段量热计中测量的电磁和强子簇射能量空间分布的一阶矩和二阶矩的方法。该技术使用在各个探测器单元中观察到的能量分数的对数加权。它快速简单，不需要拟合或复杂的位置或入射角校正。该方法证明了与GEANT模拟的BGO探测器阵列。发现位置分辨结果和e/pi分离结果等于或上级于用更复杂技术获得的结果。
A method is proposed to calculate the first and second moments of the, spatial distribution of the energy of electromagnetic and hadronic showers measured in laterally segmented calorimeters. The technique uses a logarithmic weighting of the energy fraction observed in the individual detector cells. It is fast and simple requiring no fitting or complicated corrections for the position or angle of incidence. The method is demonstrated with GEANT simulations of a BGO detector array. The position resolution results and the e/pi separation results are found to be equal or superior to those obtained with more complicated techniques.
