The Short-Baseline Neutrino (SBN) program at Fermilab, consisting of multiple Liquid Argon time projection chamber (LArTPC) detectors positioned along the Booster Neutrino Beam (BNB), presents an exciting opportunity in experimental neutrino physics. SBN is primarily designed to address the possible existence of 1 eV mass-scale sterile neutrinos through sensitive searches for both electron neutrino appearance and muon neutrino disappearance in a primarily muon neutrino beam at Fermilab. The near detector, SBND (or the Short-Baseline Near Detector), will be a new 112 ton active mass LArTPC sited only 110 m from the neutrino production target. Beginning in 2022, SBND will record millions of neutrino charged-current and neutral-current interactions on argon. By providing such a high statistics measurement of the un-oscillated content of the booster neutrino beam, SBND is a critical element in performing searches for neutrino oscillations at the SBN Program. The large data sample will also be an ideal data set for understanding the challenging physics of neutrino-nucleus scattering at the GeV energy scale. Due to the large detector mass and location close to the target, the science of SBND also includes a rich program, now under active development, for using the detector and beam to search for signatures of New Physics scenarios, in addition to the light sterile neutrino framework. The physics outputs of SBND, in particular the broad program of neutrino-argon interaction measurements, will have direct application for controlling systematic uncertainties in the future long-baseline neutrino oscillation experimental program at the long-baseline Deep Underground Neutrino Experiment (DUNE).
