Abstract

A new compressor ring for 790-MeV protons is proposed at Los Alamos National Laboratory to provide 1 MW of beam power for a spallation-neutron source. The design has unit-transfer-matrix achromatic arcs. Bunching, beam-control, and extraction elements reside in dispersionless straight sections. The arc symmetry and further high-order corrections maximize tune space available to the beam. The ring-injection scheme uses direct H^- injection and care is taken in disposing of the unstripped and partially stripped beams. The lattice design allows for transverse phase-space painting to maximize particle storage, as well as minimize stored-beam foil traversals
