Analysis of unstable leakage current in ATLAS18 Strip Sensors after long-term tests

Christoph Thomas Klein, A. Affolder, K. Affolder, J. R. Dandoy et autres

With the upgrade of the LHC to the High-Luminosity LHC (HL-LHC), the ATLAS Inner Detector will be replaced with the new all-silicon ATLAS Inner Tracker (ITk) to maintain tracking performance in a high-occupancy environment and to cope with the increase in the …

Summary of quality control (QC) of ATLAS18 production ITk strip sensors

P. Federičováa, A. Affolder, K. Affolder, A. Awais et autres

To address the demanding operational requirements of the High-Luminosity upgrade of the Large Hadron Collider (HL-LHC), the ATLAS experiment is replacing its current Inner Detector with a new all-silicon Inner Tracker (ITk). The ITk will feature an active area of 165 m2, …

Evaluation of performance of the p-stop fabrication process variations in ATLAS18 strip sensors, pre- and post-irradiation

J. Kozáková, A. Affolder, K. Affolder, A. Awais et autres

The High-Luminosity upgrade of the Large Hadron Collider (HL-LHC) requires the replacement of the ATLAS Inner Detector with a new all-silicon Inner Tracker (ITk). Radiation-hard n + -in- p micro-strip sensors were developed for use in the ITk. During quality control (QC) …

Simulation of the electrical performance of the ITk ATLAS18 test diode and strip main sensors before irradiation

Y. Zhao, C. -T. Klein, J. Dandoy, J. Keller et autres

This paper presents a two-dimensional (2D) Sentaurus TCAD model tuned using optical and electrical characterization data from test diodes fabricated on the same wafer as the strip sensors. The simulation incorporates bulk defect models extracted from deep-level transient spectroscopy (DLTS) measurements, together …

Precision calibration of calorimeter signals in the ATLAS experiment using an uncertainty-aware neural network

A.T.L.A.S. Collaboration, G. Aad, E. Aakvaag, B.K. Abbott et autres

The ATLAS experiment at the Large Hadron Collider explores the use of modern neural networks for a multi-dimensional calibration of its calorimeter signal defined by clusters of topologically connected cells (topo-clusters). The Bayesian neural network (BNN) approach not only yields a continuous …
