摘要

CMS硅条跟踪器拥有超过15000个硅模块和2亿美元的有效硅面积，已经与CMS的其他子系统一起运行了好几年。介绍了该探测器在LHC Run 2数据采集中的性能。将给出信噪比、命中效率和单命中分辨率的结果。我们回顾了系统在超出设计的瞬时亮度下运行时的行为，并描述了在这些条件下观察到的挑战。给出了探测器参数在辐射损伤影响下的演化规律，并与仿真结果进行了比较。

Operation and Performance of the CMS outer tracker

The CMS Silicon Strip Tracker with its more than 15000 silicon modules and 200 m$^2$ of active silicon area has been running together with the other subsystems of CMS for several years. We present the performance of the detector in the LHC Run 2 data taking. Results for signal-to-noise, hit efficiency and single hit resolution will be presented. We review the behavior of the system when running at beyond-design instantaneous luminosity and describe challenges observed under these conditions. The evolution of detector parameters under the influence of radiation damage are presented and compared to simulations.
