标题： First Years of Running for the LHCb Calorimeter System

摘要： LHCb量热计系统分为四个子探测器，以确保其纵向分段：一个闪烁垫探测器（SPD），随后是一个预闪光器（PS），然后是电磁（ECAL）和强子（HCAL）量热计。 在描述这些探测器之后，讨论了为校准其响应而开发的程序，以及由于恶劣条件（硬辐射和高电流）导致的响应退化。 给出了在物理数据采集最高效的两年，即2011年和2012年的量热计性能的初步结果。 显示英文摘要

摘要： The calorimeter system of LHCb is subdivided into four sub-detectors which ensure its longitudinal segmentation: a Scintillator Pad Detector (SPD) followed by a Preshower (PS) and then an electromagnetic (ECAL) an hadronic (HCAL) calorimeter. After a description of these detectors, procedures developed to calibrate their response are discussed together with the degradation of response observed due to the harsh conditions (hard radiation and high current). First results on the calorimeter performance over the two most productive years of physics data taking, 2011 and 2012 are given.
