Description
NOvA (NuMI Off-axis νe Appearance) is a long baseline neutrino oscillation experiment designed to search for both νe appearance and νμ disappearance. Fermilab NuMI (Neutrinos at Main Injector) facility produces an intense neutrino beam (narrow band νμ beam peaked at 2 GeV in energy with 700kW beam power) colliding 120 GeV protons from the Main Injector into a long target with a set of two magnetic horns (Horn1 and Horn2) to focus the pions produced at the target. We studied different target designs and Horn2 configuration to optimize the neutrino yield. Here, we present the New Target design which increases the νμ yield at the NOvA Far detector by about 21% compared to the event yield with the current NuMI target.
