论文摘要
为Calice模拟强体量热仪开发的软件补偿算法扩展以结合细胞水平的时间信息,并在Geant4模拟中研究了具有高粒状sipm-in tile量热量表的检测器模型。与基于本地能量密度相比,本地软件补偿的纳秒级时分辨率的添加可显着改善能源分辨率约3%至4%,仅基于局部能量密度,可以通过局部能量密度进行大量改善,并且可以通过更好的定时分辨率进一步改善。能量密度和时间变量的高相关性表明,两者都对相关的基础淋浴特征提供了敏感性,这限制了将定时信息用作全局而不是局部变量的潜力。
The software compensation algorithms developed for the CALICE Analog Hadron Calorimeter are extended to incorporate time information on the cell level, and the performance is studied in GEANT4 simulations with a detector model of a highly-granular SiPM-on-tile calorimeter. The addition of nanosecond-level time resolution is found to result in significant improvement of the energy resolution by approximately 3% to 4% for local software compensation compared to the software compensation based on local energy density alone, with further improvement possible with better timing resolution. The high correlation of energy density and time variables show that both provide sensitivity to correlated underlying shower features, which limits the potential of timing information when used as a global rather than a local variable.
