MicroBooNE is a neutrino experiment at Fermi National Laboratory that will look for the possible existence of new physics beyond the Standard Model. One way it will do this will be to study precisely how a beam of neutrinos of a certain type (from muon neutrinos) changes into another (to electron neutrinos). The detector technology MicroBooNE employs — Liquid Argon Time projection chambers — provide very high-resolution images of the interactions. This allows it to remove certain backgrounds more efficiently than previous experiments.
Fun link: someone (not anyone in this group) made a 3D-printable model of the MicroBooNE detector!
