A new neutrino detector under construction at DOE’s Fermi National Accelerator Laboratory just got its first glimpse at how the elusive particle interacts with matter. On April 1, the first portion of the MINERvA detector, comprised of 24 modules, observed its first neutrinos. When the detector is fully assembled in 2010, it will have 108 modules, each about two inches thick. Using a high-intensity beam of neutrinos provided by the Fermilab accelerator complex, the MINERvA collaboration will study low-energy neutrino interactions, including the strong dynamics of the nucleon and nucleus that affects these interactions. “This is a huge milestone for us,” said MINERvA cospokesperson Kevin McFarland, of the University of Rochester.
