大型强子对撞机预测，在2030年之前，峰值亮度将从2022年增加到105 ×1034cm−2s−1，积分亮度为10300fb −1。目前的ATLAS内部探测器将无法承受预测的辐射水平，也无法承受预期的命中率大幅增加。因此，必须在相对较短的时间内设计、建造和安装新的内部跟踪器。目前的布局假设一个全硅跟踪器与像素探测器的最内层和带模块在更高的半径。主要的限制因素是抗辐射传感器、高效配电、最低材料预算、可承受的成本以及快速可靠的生产。本说明报告了用于升级的ATLAS内部跟踪器的短带区域的双面硅带模块的设计。描述了模块的不同组件。讨论了其热性能。第一模块原型的组装顺序进行了详细说明。
The LHC foresees a peak luminosity increase of up to ∼5×1034cm−2s−1 from ∼2022 with an integrated luminosity of ∼3000fb−1 before 2030. The current ATLAS Inner Detector will not stand the predicted radiation levels nor the expected large increase in the hit occupancy rates. A new inner tracker must therefore be designed, built and installed in a relatively short time-scale. The current layout assumes an all-silicon tracker with pixel detectors for the innermost layers and strip modules at higher radii. Major constraints are the requirements of radiation-hard sensors, efficient power distribution, minimum material budget, affordable cost, and fast and reliable production. This note reports on the design of double-sided silicon strip modules for the short-strip region of the upgraded ATLAS inner tracker. The different components of the module are described. The thermal performance is discussed. The assembly sequence of first module prototypes is explained in detail.
