ATLAS探测器的Tile强子量能器自2005年底安装以来，已经在实验大厅进行了广泛的测试。自2007年以来，读出、控制和校准系统已全面投入运行，探测器已成功收集了2008年LHC单束和2009年首次碰撞的数据。本文概述了瓦量热计的性能，测量使用随机触发，校准数据，宇宙射线μ子和单束数据的数据。探测器的运行状态，噪声特性和校准系统的性能，以及最小电离宇宙线μ子数据进行的时间和能量校准的验证。校准系统的精度远低于1%的设计值。全球能量标度的确定是在4%的不确定度下进行的。
The Tile hadronic calorimeter of the ATLAS detector has undergone extensive testing in the experimental hall since its installation in late 2005. The readout, control and calibration systems have been fully operational since 2007 and the detector has successfully collected data from the LHC single beams in 2008 and first collisions in 2009. This paper gives an overview of the Tile Calorimeter performance as measured using random triggers, calibration data, data from cosmic ray muons and single beam data. The detector operation status, noise characteristics and performance of the calibration systems are presented, as well as the validation of the timing and energy calibration carried out with minimum ionising cosmic ray muons data. The calibration systems' precision is well below the design value of 1%. The determination of the global energy scale was performed with an uncertainty of 4%.
