AI 中文摘要
为提高大型强子对撞机高亮度升级（HL-LHC）运行时ATLAS缪子探测器的缪子触发效率和速率承载能力，ATLAS缪子谱仪内桶层的监测漂移管（MDT）探测室将被集成新型窄间隙RPC触发室的小直径缪子漂移管（sMDT）探测室替代。sMDT探测室自2021年1月起进入批量生产，本文档提供了慕尼黑MPI开展的漂移管生产及探测室建造各步骤的详细信息。批量生产包含严格的质量控制程序，以保证探测室的可靠性和高机械精度，该程序涵盖单个漂移管测试、探测室几何测量和气密性验证，生产现场通过宇宙射线完成最终认证。本文还介绍了供sMDT探测室两个生产站点共用的专用质量控制数据库及监控网页界面。
英文摘要
In order to improve the muon trigger efficiency and the rate capability of the ATLAS muon detectors for operation at the high luminosity upgrade of the Large Hadron Collider (HL-LHC), the Monitored Drift Tube (MDT) tracking chambers in the inner barrel layer of the ATLAS Muon Spectrometer will be replaced by small-diameter Muon Drift Tube (sMDT) chambers integrated with new thin-gap RPC trigger chambers. The sMDT chambers are in serial production since January 2021. This documentation provides insight into the drift tube production and every step performed in the chamber construction at the MPI Munich. The serial production involves a stringent quality control program to assure the reliability and high mechanical precision of the chambers. This program consists of tests of the individual drift tubes, measurements of the chamber geometry and proof of gas tightness. Final certification at the production site is provided using cosmic rays. The dedicated quality control database and monitoring Web interface that is used commonly for both production sites of the sMDT chambers is presented
