Neutrino Team

The P-25 Neutrino Team performs sterile neutrino and dark matter searches at Fermilab using the MiniBooNE, MicroBooNE, SBND, and ICARUS detectors. MiniBooNE and MicroBooNE are actively taking data, while SBND and ICARUS are under construction.

Major Projects
  • The ICARUS detector is a rectangular LAr TPC that is now being transported from CERN to Fermilab. The TPC has an active volume of 476 tons and will be located 600 m from the neutrino source. ICARUS will have the best sensitivity for neutrino oscillations and sterile neutrinos.
  • The MicroBooNE neutrino experiment has been taking data at Fermilab since 2015. The detector consists of a cylindrical liquid argon (LAr) TPC with an active volume of 89 tons that is located 470 m from the neutrino source. MicroBooNE will determine whether the excess of electron-like events observed by MiniBooNE is due to electrons or gammas.
  • The MiniBooNE neutrino experiment has been taking data at Fermilab since 2002. The detector consists of a 12.2 m diameter sphere filled with 800 tons of mineral oil and covered by 1520 8-inch photomultiplier tubes. The detector is located 541 m from the neutrino source. MiniBooNE has observed a 3.8 sigma excess of electron candidate events that are consistent with muon-neutrino to electron-neutrino oscillations. MiniBooNE has also measured neutrino cross sections on carbon and has searched for low-mass dark matter
  • MiniCAPTAIN
  • The Short Baseline Neutrino Detector (SBND) is under construction at Fermilab and will consist of a rectangular LAr TPC with an active volume of 112 tons that is located 110 m from the neutrino source. SBND will measure neutrino cross sections on argon and will determine the intrinsic neutrino background for searches for neutrino oscillations and sterile neutrinos.
