Work to fill the NOvA far-detector blocks in Ash River, Minn., with scintillator oil began last week. Here, a Wayne Transport truck unloads the scintillator oil that will fill the NOvA far-detector blocks. When a neutrino strikes an atom in the liquid scintillator that fills the 15-kiloton far detector, it releases a burst of charged particles. Scientists can detect these particles and use them to learn about neutrino interactions.
