摘要

欧洲核子研究中心(CERN)的大型强子对撞机(LHC)的光度将提升到7。5 × 10 34 cm−1 s−2。光度的增加导致探测器中粒子通量和电离剂量的增加。CMS实验的跟踪探测器将进行升级，以适应新的运行条件。用于CMS内部跟踪器升级的原型混合像素传感器由三家不同的制造商生产，具有矩形100µm × 25µm像素，并由RD53A芯片读出，对辐照前后的影响进行了表征，其影响高达Φ eq = 2。0 × 10 16cm−2。本文的表征结果表明，所有传感器都满足高亮度LHC的工作要求。

Characterization of Planar Pixel Sensors for the High-Luminosity Upgrade of the CMS Detector

The luminosity of the Large Hadron Collider (LHC) at CERN will be upgraded to 7 . 5 × 10 34 cm − 1 s − 2 . The increased luminosity leads to an increased particle ﬂuence and ionizing dose in the detectors. The tracking detectors of the CMS experiment will be upgraded in order to cope with the new operating conditions. Prototype hybrid pixels sensors for the CMS Inner Tracker upgrade with rectangular 100 µ m × 25 µ m pixels produced by three diﬀerent manufacturers and readout by the RD53A chip were characterized before and after irradiation to ﬂuences up to Φ eq = 2 . 0 × 10 16 cm − 2 . The characterization results presented in this paper demonstrate that all sensors meet the requirements for operation at the high-luminosity LHC.
