Short-Baseline Near Detector (SBND)

The Short-Baseline Near Detector (SBND) will be one of three liquid argon neutrino detectors sitting in the Booster Neutrino Beam (BNB) at Fermilab as part of the Short-Baseline Neutrino Program. MicroBooNE and ICARUS are the intermediate and far detectors in the program, respectively.

SBND is a 112 ton active volume liquid argon time projection chamber (LArTPC) to be located only 110 m from the BNB neutrino source. The detector is currently being assembled and is anticipated to begin operation in 2023.

SBND will record over a million neutrino interactions per year. By providing such a high statistics measurement of the un-oscillated content of the booster neutrino beam, SBND plays a critical role in performing searches for neutrino oscillations at the Fermilab Short-Baseline Program. The large data sample will also allow studies of neutrino-argon interactions in the GeV energy range with unprecedented precision. The physics of these interactions is an important element of future neutrino experiments that will employ the LArTPC technology, such as the long-baseline Deep Underground Neutrino Experiment, DUNE.
