PY - 2021 DA - 2021// TI - Measurements of sensor radiation damage in the ATLAS inner detector using leakage currents T2 - J. Instrum. JO - Journal of Instrumentation SP - P08025 - 46pp VL - 16 IS - 8 PB - IOP Publishing Ltd KW - Radiation damage to detector materials (solid state) KW - Detector modelling and simulations I (interaction of radiation with matter KW - interaction of photons with matter KW - interaction of hadrons with matter KW - etc) AB - Non-ionizing energy loss causes bulk damage to the silicon sensors of the ATLAS pixel and strip detectors. This damage has important implications for data-taking operations, charged-particle track reconstruction, detector simulations, and physics analysis. This paper presents simulations and measurements of the leakage current in the ATLAS pixel detector and semiconductor tracker as a function of location in the detector and time, using data collected in Run 1 (2010-2012) and Run 2 (2015-2018) of the Large Hadron Collider. The extracted fluence shows a much stronger vertical bar z vertical bar-dependence in the innermost layers than is seen in simulation. Furthermore, the overall fluence on the second innermost layer is significantly higher than in simulation, with better agreement in layers at higher radii. These measurements are important for validating the simulation models and can be used in part to justify safety factors for future detector designs and interventions.
