The MINERνA Detector (http://minerva.fnal.gov) (Main Injector ExpeRiment νA) is a high statistics experiment in the Fermilab NuMI line. Its main goals are to measure the interactions neutrino (antineutrino) Nucleus at low energies in order to improve neutrino oscillation studies and study the dynamics between neutrinos (antineutrino) and nucleons within nuclei. The detector is completely installed and collecting data. For calibration, the MINERνA collaboration created the MINERνA Test Beam experiment. This was designed, constructed and commissioned successfully. In summer of 2010, it finished its first data run; analyzes are in progress. I'll report on this successful calibration experiment and present some preliminary results.
