Fermilab’s NOvA neutrino experiment studies neutrino oscillations using a powerful neutrino beam produced by the lab’s accelerator complex. The beam, made of muon neutrinos, is sent to NOvA’s two detectors — one located at Fermilab and one located about 800 kilometers away in Minnesota pictured here. The NOvA far detector looks to identify the fraction of muon neutrinos in the NuMI beam that oscillated into electron neutrinos and the fraction of muon neutrinos that oscillated to a different flavor.
