Detector Physics Measurements and Calibrations in the MicroBooNE LArTPC

The MicroBooNE liquid argon time projection chamber (LArTPC) experiment was exposed to Fermilab's Booster and NUMI neutrino beams from 2015 to 2021, and has since established a rich and active physics program. MicroBooNE utilizes both the ionization charge and scintillation light produced inside the TPC to select and reconstruct its events. Crucial to the experiment's physics program is a detailed understanding of the detector's performance over time. This talk will summarize the experiment's state-of-the-art measurements of detector physics quantities such as electron lifetime, diffusion, and scintillation light yield. In addition, MicroBooNE has developed and demonstrated novel capabilities in light-based nanosecond interaction timing resolution and MeV-scale reconstruction and calibration of charge signals, both of which are foundational to expanding the physics reach of future LArTPC detectors.
