The MicroBooNE Experiment

Located at Fermilab, the MicroBooNE collaboration is currently operating a large 170 ton Liquid Argon Time Projection Chamber (LAr TPC) that is located on the Booster neutrino beam line at Fermilab. The experiment first started collecting neutrino data in October 2015. MicroBooNE will measure low energy neutrino cross sections and investigate the low energy excess events observed by the MiniBooNE experiment. The detector also serves as a next step in a phased program towards the construction of massive kiloton scale LAr TPC detectors for future long-baseline neutrino physics (DUNE) and is the first detector in the short-baseline neutrino program at Fermilab.
