This photo shows the ground electrode of the negative-hydrogen-ion source for the Project X Injector Experiment. The source, manufactured by D-Pace Inc. and licensed from TRIUMF laboratory in Vancouver, Canada, will be installed next month at Fermilab’s Cryomodule Test Facility. Once operating, it will produce ionized hydrogen atoms in its plasma chamber (not shown) and extract them through the aperture (into the plane of the picture) to form particle beams.

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.
