SUPERCONDUCTINGCAVITIES FOR NEUTRON SPALLATIONSOURCES AND OTHER HIGH INTENSITY PROTON ACCELERATORS

High intensity linear proton or deuteron accelerators are at present intensively studied for applications in pulsed spallation sources, for fusion material research and for nuclear waste transmutation. Superconducting cavities could offer an interesting option for high intensity linacs. The specific merits and the requirements for their use are reviewed and illustrated by the proposal of a 5 MW pulsed European Spallation Source and by a CW linear accelerator considered at Los Alamos for nuclear waste transmutation.
