The semiconductor tracker (SCT) is one of the tracking systems for charged particles in the ATLAS detector. It consists of 4088 silicon strip sensor modules. During Run 2 (2015–2018) the Large Hadron Collider delivered an integrated luminosity of 156 fb^-1 to the ATLAS experiment at a centre-of-mass proton-proton collision energy of 13 TeV. The instantaneous luminosity and pile-up conditions were far in excess of those assumed in the original design of the SCT detector. Due to improvements to the data acquisition system, the SCT operated stably throughout Run 2. It was available for 99.9% of the integrated luminosity and achieved a data-quality efficiency of 99.85%. Detailed studies have been made of the leakage current in SCT modules and the evolution of the full depletion voltage, which are used to study the impact of radiation damage to the modules.

LHC Run 2 中 ATLAS 半导体跟踪器的操作和性能

半导体跟踪器（SCT）是ATLAS探测器中带电粒子跟踪系统之一。它由4088个硅条传感器模块组成。在第 2 次运行（2015-2018 年）期间，大型强子对撞机提供了 156 fb ^{-1的综合光度}在 13 TeV 的质心质子-质子碰撞能量下进行 ATLAS 实验。瞬时光度和堆积条件远远超过 SCT 探测器原始设计中假设的条件。由于数据采集系统的改进，SCT 在整个运行 2 中稳定运行。它可用于 99.9% 的集成光度，并实现了 99.85% 的数据质量效率。详细研究了SCT组件中的漏电流和全耗尽电压的演变，用于研究辐射损伤对组件的影响。
