Description
"The High-Granularity Timing Detector (HGTD) is an important upgrade of the ATLAS detector for the HL-LHC, providing precise timing information in the forward region to reduce the impact of high pileup. A reliable timing calibration is therefore essential for stable detector performance.
In this study, different calibration granularities are investigated using simulated samples, from large detector regions down to individual modules. Independent samples are used for calibration and performance evaluation, and the dependence on available statistics is also studied. A timing residual of about 26 ps is achieved for most calibration granularities, while module-level calibration requires significantly more statistics.
This presentation will introduce the HGTD timing calibration method, compare different calibration granularities, and summarize the latest validation results."
