摘要:

为ATLAS像素探测器的每个切片构建了演示装置,用于复刻真实探测器,并为其组件的运行与维护提供早期解决方案。本次针对欧洲核子研究中心(CERN)高亮度大型强子对撞机(HL-LHC)上ATLAS实验的全硅内跟踪器(ITk)像素探测器的系统级测试,涵盖了广泛的系统组件,这对于应对HL-LHC预期提升的亮度与辐射水平、进而提升径迹测量性能至关重要。借助先进的硅传感器技术、串行供电方案以及轻质碳纤维结构,演示装置与支撑结构上组装的组件将接受多项验证与调试研究。研究团队针对串行供电、监测系统和数据采集开展了大量测试,确保该系统在未来高能物理实验中的鲁棒性与可靠性。此外,还将介绍新型ITk像素探测器的三个不同子组件,它们分别专为外桶(OB)、外端盖(OEC)和内部系统(IS)部分设计。

英文摘要:

A demonstrator for each slice of the ATLAS pixel detector was built to replicate the real detector and provide early solutions for operating and maintaining its components. This system-level testing of the all-silicon Inner Tracker (ITk) pixel detector for the ATLAS experiment at CERN's HL LHC encompasses a wide array of system components, which is essential for managing the increased luminosity and radiation levels expected at HL LHC, thereby enhancing tracking performance. Utilizing advanced silicon sensor technologies, serial powering, and lightweight carbon fiber structures, the demonstrator and assembled components on the support structure will undergo several studies for verification and commissioning. Extensive tests on serial powering, monitoring, and data acquisition were conducted, ensuring the system's robustness and reliability for future high-energy physics experiments. Additionally, three different sub-components will be introduced for the novel ITk pixel detector, specifically designed for the outer barrel (OB), outer end caps (OEC), and inner system (IS) sections.
