Atlas半导体跟踪器的性能和运行经验

Performance and operation experience of the Atlas Semiconductor Tracker

Zhijun Liang

摘要:

我们报告的操作和性能的ATLAS半导体跟踪器(SCT),这已经在欧洲核子研究中心的大型强子对撞机的高亮度,高辐射环境中运行了3年。我们还报告了几个改进的SCT预见到高能量运行的LHC。我们发现SCT模块的$99.3\%$是可操作的,噪声占用和命中效率超过设计规格;对准非常接近理想,允许在线轨道重建和不变质量确定。我们将报告检测器的操作和性能,包括所遇到问题的概述。我们观察到一个显着增加,由于非电离辐射的散装损坏的泄漏电流,并与预测进行比较。

英文摘要:

We report on the operation and performance of the ATLAS Semi-Conductor Tracker (SCT), which has been functioning for 3 years in the high luminosity, high radiation environment of the Large Hadron Collider at CERN. We also report on the few improvements of the SCT foreseen for the high energy run of the LHC. We find $99.3\%$ of the SCT modules are operational, the noise occupancy and hit efficiency exceed the design specifications; the alignment is very close to the ideal to allow on-line track reconstruction and invariant mass determination. We will report on the operation and performance of the detector including an overview of the issues encountered. We observe a significant increase in leakage currents from bulk damage due to non-ionizing radiation and make comparisons with the predictions.
