MINOS+ was a continuation of the MINOS experiment (Main injector neutrino oscillation search) to measure neutrino oscillation with improved electronics.
The experiment has ended and a 6-month dismantling project began in early October 2016.
To produce the beamline, 120 GeV proton pulses from the Main Injector hit a water-cooled graphite target.
The resulting interactions of protons with the target material produce pions and kaons, which are focused by a system of magnetic horns.
NOνA sits 14 milliradians off the central line of the NuMI beam.
