Upgrades to the Fermilab NuMI beamline

The NuMI beamline at Fermilab has been delivering high-intensity muon neutrino beams to the MINOS experiment since the spring of 2005. A total of 3.4 times 10
²⁰
protons has been delivered to the NuMI target and a maximum beam power of 320 kW has been achieved. An upgrade of the NuMI facility increasing the beam power capability to 700 kW is planned as part of the NOvA experiment. The plans for this upgrade are presented and the possibility of upgrading the NuMI beamline to handle 1.2 MW is considered.
