CERN高亮度LHC（HL-LHC）升级版ATLAS探测器的新型内跟踪器（ITk）的条形传感器已成功完成预生产交付，并根据其性能开始全面生产。整个交付期预计将持续4年，以完成ITk所需的约22000个传感器。对于质量保证（QA），由Hamamatsu Photonics KK（HPK）代工厂在每个晶圆上生产由合作设计的许多测试结构，沿着大面积二极管和主传感器的微型版本。除了对每个主要传感器进行质量控制（QC）检查外，每个交付批次的QA样品在辐照前后都进行了测试，结果是在暴露于中子、伽马或质子后，其通量和剂量相当于HL-LHC运行后预期的通量和剂量，约为4000 fb-1最终积分光度的1.5倍。在本文中，介绍了程序，并进行了研究，以确定七个ITk QA条传感器辐照和测试地点满足所有要求，以支持整个ITk项目的条传感器生产阶段的这一非常广泛的计划。
The successful pre-production delivery of strip sensors for the new Inner Tracker (ITk) for the upgraded ATLAS detector at the High Luminosity LHC (HL-LHC) at CERN was completed and based on their performance full production has commenced. The overall delivery period is anticipated to last 4 years to complete the approximately 22000 sensors required for the ITk. For Quality Assurance (QA), a number of test structures designed by the collaboration, along with a large area diode and miniature version of the main sensor, are produced in every wafer by the foundry Hamamatsu Photonics KK (HPK). As well as Quality Control (QC) checks on every main sensor, samples of the QA pieces from each delivery batch are tested both before and after irradiation with results after exposure to neutrons, gammas or protons to fluences and doses corresponding to those anticipated after operation at the HL-LHC to roughly 1.5 times the ultimate integrated luminosity of 4000 fb-1. In this paper the procedures are presented and the studies carried out to establish that the seven ITk QA Strip Sensor irradiation and test sites meet all the requirements to support this very extensive programme throughout the strip sensor production phase for the ITk project.
