\subsection{Neutrino source}  The NuMI beam used by NO$\nu$A is fueled by proton collisions that are harnessed by an 8 GeV Booster accelerator and stored in the Main Injector ring. The Small ortions of the  Main Injector beam is extracted are diverted  using 6 sets of magnets and directed down a 350m long path to the NuMI sector where it is focused to a graphite cylinder with dimensions of 6.4x15x940 mm^3. At the point of contact, the beam is 1mm in diameter. The graphite target is separated in into  47 different fins each individually cooled in a stainless steel vacuum canister. The pions that are emitted as a result of the decay are focused by two magnetic horns with maximum of 30 kG of magnetic field, produced by 200 kA of current, that act as a particle selector, filtering out everything but positively charged pions. For increased adjustability, the target is mounted on a rail system.
