ATLAS ITk strip sensor quality assurance tests and results of ATLAS18 pre-production sensors

Popis výsledku v původním jazyce

Towards the high luminosity (HL) operation of the Large Hadron Collider (LHC), the inner tracking system of the ATLAS detector will be replaced by a fully silicon-based inner tracker (ITk). Its outer region consists of 17,888 n+-in-p silicon strip sensors. In order to confirm key properties of the production sensors as well as to establish a solid workflow of quality inspection and monitoring of the various sensor properties, about 5% of the total strip sensors were produced in 2020 as a preproduction run. As a quality assurance (QA) program, irradiation of dedicated QA test pieces was periodically performed. The fluences of proton, neutron and γ-ray irradiations were up to 1.6×1015 1MeVneutrons/cm2 and 0.66 MGy,whichareequivalent to the maximum expected radiation fluences at the HL-LHC operation with a safety factor of 1.5. Results from 154 QA test pieces demonstrated high quality of the strip sensors through the pre-production. Detailed understanding of post-irradiated strip sensors was acquired, and the procedures of irradiation and post-irradiation QA testing were fully established. Consequently, the 3.8-year project of the strip sensor production for the ATLAS ITk detector was initiated in July 2021.
