The inner detector of the present ATLAS experiment has been designed and developed to function in the environment of the present Large Hadron Collider (LHC). At the ATLAS Phase-II Upgrade, the particle densities and radiation levels will exceed current levels by a factor of ten. The instantaneous luminosity is expected to reach unprecedented values, resulting in up to 200 proton-proton interactions in a typical bunch crossing. The new detectors must be faster and they need to be more highly segmented. The sensors used also need to be far more resistant to radiation, and they require much greater power delivery to the front-end systems. At the same time, they cannot introduce excess material which could undermine tracking performance. For those reasons, the inner tracker of the ATLAS detector was redesigned and will be rebuilt completely. The ATLAS Upgrade Inner Tracker (ITk) consists of several layers of silicon particle detectors. The innermost layers will be composed of silicon pixel sensors, and the outer layers will consist of silicon microstrip sensors. This contribution focuses on the strip region of the ITk. The central part of the strip tracker (barrel) will be composed of rectangular short (∼2.5 cm) and long (∼5 cm) strip sensors. The forward regions of the strip tracker (end-caps) consist of six disks per side, with trapezoidal shaped sensors of various lengths and strip pitches. After the completion of final design reviews in key areas, such as Sensors, Modules, Front-End electronics, and ASICs, a large scale prototyping program has been completed in all areas successfully. We present an overview of the Strip System and highlight the final design choices of sensors, module designs and ASICs. We will summarise results achieved during prototyping and the current status of pre-production and production on various detector components, with an emphasis on QA and QC procedures.

用于第二阶段升级的 ATLAS ITk 条带检测器

目前 ATLAS 实验的内部探测器是为在现有大型强子对撞机 (LHC) 环境中运行而设计和开发的。在 ATLAS 第二阶段升级中，粒子密度和辐射水平将超过当前水平十倍。瞬时光度预计将达到前所未有的值，在典型的束团交叉中产生多达 200 次质子-质子相互作用。新的探测器必须更快，并且需要更高度分段。所使用的传感器还需要具有更强的抗辐射能力，并且需要向前端系统提供更大的功率。同时，他们不能引入过多的材料，这可能会损害跟踪性能。由于这些原因，ATLAS探测器的内部跟踪器被重新设计，并将被完全重建。 ATLAS 升级内部跟踪器 (ITk) 由多层硅粒子探测器组成。最内层将由硅像素传感器组成，外层将由硅微带传感器组成。本贡献重点关注 ITk 的地带区域。带材跟踪器（桶）的中心部分将由矩形短（∼2.5 cm）和长（∼5 cm）带材传感器组成。带材跟踪器的前部区域（端盖）每侧由六个圆盘组成，带有不同长度和带材节距的梯形传感器。在完成传感器、模块、前端电子设备和 ASIC 等关键领域的最终设计审查后，所有领域的大规模原型设计计划均已成功完成。我们概述了 Strip 系统，并重点介绍了传感器、模块设计和 ASIC 的最终设计选择。我们将总结原型设计过程中取得的成果以及各种探测器组件预生产和生产的现状，重点是质量保证和质量控制程序。
