\subsection{Upgrades to NuMI}
As part of the NO$\nu$A project, a series of upgrades were installed in the NuMI beam infrastructure to provide a higher intensity neutrino beam than before possible. The first of which is an adaptation of the Recylcer ring from the recently concluded collider run, which used to store anti-protons, to be used as a pre-injector to the Main Injector beam. This reduces the from 2.2 seconds to 1.3, allowing the Main Injector to ramp up at the same time as the next injection to the loop \cite{Patterson_2012}, resulting in an 80\% increase in the beam power while only increasing the number of protons per bunch by 10\%. In order to support this addition to the Main Injector, the magnets used to deflect the NuMI line must be upgraded to support the additional beam power. Furthermore, the target was upgraded with a new cooling system. There are two possible upgrades that are being discussed at Fermilab. The first, "SNuMI", uses the Accumulator ring to stack multiple proton packets from the booster ring in order to increase the beam flux. This would increase the NuMI beam to 1.2 MW. The second, dubbed "Project X" is to replace the Booster ring all togther with a proton linear acceleration to be built which owuld increase the beam intensity to 2.3 MW \footnote{This data comes from Fermilab at http://www-nova.fnal.gov/nova_beam_anu.html}.
