INTRODUCTION
These webpages describe MicroBooNE, an experiment
with stage-1 approval at Fermilab to build a large liquid Argon Time
Projection Chamber (LArTPC) that will be exposed to the Booster neutrino beam
and the NuMI neutrino beam. The experiment will address the
low energy excess observed by the MiniBooNE experiment, measure low
energy neutrino cross sections, and serve as the necessary next step
in a phased program towards massive Liquid Argon TPC detectors.
