MicroBooNE: Liquid argon TPC at Fermilab

MicroBooNE is a short baseline neutrino oscillation experiment at the Fermi National Accelerator Laboratory which will use neutrinos from the Booster Neutrino Beam (BNB) using a 170 ton liquid-argon Time Projection Chamber (LArTPC). The primary physics goal of the experiment is to answer the question of whether the observed low energy excess in the MiniBooNE data, which could be interpreted as an oscillation signal involving sterile neutrinos, is related to an excess of single electron or single photon events. While both experiments are exposed to a similar neutrino flux, MicroBooNE will have excellent particle identification, tracking, and calorimetry information, which will significantly improve the background and signal separation. The experiment is also an important R and D project for future LArTPC experiments in terms of both detector technology and physics including measurements of low energy neutrino cross-sections.
