2009年12月，ATLAS实验在质心能量为0.9 TeV和2.36 TeV时收集了50多万次LHC碰撞数据的最小偏差事件。本文报告的ATLAS探测器从这些数据的初始性能的研究。数据和蒙特卡罗预测之间的比较显示几个轨道和量热计为基础的数量的分布。ATLAS探测器在这些第一批数据中的良好性能为在更高能量下成功运行提供了信心。
More than half a million minimum-bias events of LHC collision data were collected by the ATLAS experiment in December 2009 at centre-of-mass energies of 0.9 TeV and 2.36 TeV. This paper reports on studies of the initial performance of the ATLAS detector from these data. Comparisons between data and Monte Carlo predictions are shown for distributions of several track- and calorimeter-based quantities. The good performance of the ATLAS detector in these first data gives confidence for successful running at higher energies.
