【 摘 要 】

The primary goal of the NOνA neutrino oscillation experiment is to study the probabilities of transformation of muonic-neutrinos into electron-neutrinos. The experiment is currently under construction and will use a 700 kW accelerator-based NuMI beam (Neutrinos at the Main Injector) and two detectors. The Near Detector (329 t at Fermi National Accelerator Laboratory, Illinois) and the Far Detector (14 kt, Ash River, Minnesota) are aligned to 14 mrad off-axis and separated by 810 km. They are made of active liquid scintillator and readout by avalanche photo-diodes. Recent results from world-wide neutrino experiments indicate that NOνA is in the position to determine the neutrino mass hierarchy as it is also searching for the first hints of CP violation in neutrino sector. The design, the goals and the current status of the NOνA experiment are presented here with the current estimates of its sensitivity to the mass hierarchy measurement.
