II.15 — High-power proton linacs

High-power proton linacs are envisaged as drivers for numerous applications, such as neutron spallation sources for condensed matter study, neutrino factories, muon colliders, hybrid systems for transmutation or energy production, production of rare isotope beams for nuclear physics studies, etc. These linear accelerators are intended to deliver proton beams of up to several MW and tens of MW power and operate with CW or pulsed high-intensity beams. In the rest of this chapter, these accelerator types will be discussed with a focus on one or two projects as examples to demonstrate the building blocks of accelerators and their applications.
