Abstract

New low-cost, high-power proton cyclotrons open the opportunity for a novel precision search for CP violation in the neutrino sector. The accelerators can produce decay-at-rest neutrino beams located at multiple distances from a Gd-doped ultra-large water Cerenkov detector in order to search for CP violation in anti-nu_mu to anti-nu_e at short baseline. This new type of search complements presently proposed experiments, providing measurements that could lead to a substantially better exploration of CP violation in the neutrino sector.
