论文摘要

描述了LHC在运行1和2中LHCB量热计系统的校准和性能。在对子检测器及其在触发器中的作用进行了简要描述后，审查了用于系统每个部分的校准方法。解释了随着运行2中的梁能量增加而发生的变化。详细介绍了$γ$和$π^0 $的量热法的性能。显示了以$ \ sqrt {s} $ = 7、8和13 TEV记录的碰撞结果。

The calibration and performance of the LHCb Calorimeter system in Run 1 and 2 at the LHC are described. After a brief description of the sub-detectors and of their role in the trigger, the calibration methods used for each part of the system are reviewed. The changes which occurred with the increase of beam energy in Run 2 are explained. The performances of the calorimetry for $γ$ and $π^0$ are detailed. A few results from collisions recorded at $\sqrt {s}$ = 7, 8 and 13 TeV are shown.
