Overview of the MicroBooNE LArTPC Detector Calibration

The MicroBooNE experiment at Fermilab uses a liquid argon time projection chamber (LArTPC) to investigate the excess of low energy electromagnetic events observed by the MiniBooNE experiment and measure neutrino-argon cross sections. LArTPCs provide exceptional calorimetry and tracking capabilities to reconstruct both particle track direction and energy with high precision. Effects such as non-optimally performing TPC channels, space charge effects, electron attenuation, diffusion and recombination will degrade the energy resolution of the detector and thereby impact particle identification of the neutrino final states. Therefore, precision calibration is absolutely essential to achieve the experiment’s physics goal. We will give an overview on how the MicroBooNE LArTPC detector calibration is carried out and the status of calibration measurements using MicroBooNE data.
