Detector Physics with MicroBooNE

The MicroBooNE detector is a liquid argon time projection chamber (LArTPC), designed for the short-baseline neutrino physics program in the Booster neutrino beamline at Fermilab. Because of their exceptional calorimetric and tracking capabilities, LArTPCs are employed in many current and future neutrino experiments. MicroBooNE, as an operating physics experiment, plays a crucial role in characterising the performance of this technology. We present an overview of the ongoing detector physics studies in MicroBooNE, including a brief introduction to the detector sub-systems and a procedure for calibrating calorimetry in LArTPC. The latter involves studies of signal processing, charge uniformity, ionised electron lifetime and charge recombination. Through the laser system in MicroBooNE, we demonstrate that profound knowledge of the electric field is essential to conduct a neutrino experiment with LArTPCs.
