The next generation of high energy physics experiments will require high intensity proton beams with currents in excess of 10 milliAmps. In order to provide these high intensity beams, a new generation of high power proton accelerators is required. These high power proton accelerators will form the basis for a broad range of accelerator facilities, including upgrades to the Large Hadron Collider at CERN, neutron scattering measurements at high intensity neutron spallation sources, high flux neutron beams at a neutrino factory and future energy sources in the form of nuclear waste transmutation and accelerator driven sub-critical reactors.
