the first UV laser track seen in the MicroBooNE TPC (drift HV at 58 kV) - see more images here!

The MicroBooNE Experiment

Located at Fermilab, the experiment will build and operate a large 170 ton Liquid Argon Time Projection Chamber (LArTPC) located along the Booster neutrino beam line. The experiment will measure low energy neutrino cross sections and investigate the low energy excess events observed by the MiniBooNE experiment. The detector serves as a next step in a phased program towards the construction of massive kiloton scale LArTPC detectors.
