LHCb外跟踪器是一种气体探测器，覆盖面积为5 x 6 m（2），具有12个双层吸管。探测器及其服务与调试和校准程序一起描述。基于2010 - 2012年LHC首个运行周期的数据，介绍了LHC读出电子学的性能以及单次命中的分辨率和效率，估算出在吸管中半部分探测命中的效率为99.2%，位置分辨率约为200 μ m。外跟踪器在最热区域接受了相当于0.12 C/cm的剂量，未观察到增益退化或其他老化效应的迹象。
The LHCb Outer Tracker is a gaseous detector covering an area of 5 x 6 m(2) with 12 double layers of straw tubes. The detector with its services are described together with the commissioning and calibration procedures. Based on data of the first LHC running period from 2010 to 2012, the performance of the readout electronics and the single hit resolution and efficiency are presented.The efficiency to detect a hit in the central half of the straw is estimated to be 99.2%, and the position resolution is determined to be approximately 200 mu m. The Outer Tracker received a dose in the hottest region corresponding to 0.12 C/cm, and no signs of gain deterioration or other ageing effects are observed.
