Neutrino physics is very much at the forefront of today's research. Large detectors installed in deep underground locations study neutrino masses, CP violation, and oscillations using neutrino-sources including long- and short-baseline beams of neutrinos from muons decaying in flight. DAEdALUS* looks at neutrinos from stopped muons, “Decay At Rest (DAR)” neutrinos. The DAR neutrino spectrum has no electron antineutrinos (nu-e-bar) (pi-minus are absorbed), so a detector with much hydrogen (water-Cherenkov or liquid scintillator) is sensitive to appearance of nu-e-bar’s oscillating from nu-mu-bar via inverse-beta-decay. Oscillations are studied using shorter baselines, less than 20 km reaching the same range as the current and planned high-energy neutrino lines at Fermilab. As the neutrino flux is not variable, nor is the energy, the baseline is varied, plans call for 3 accelerator-based neutrino sources at 1.5, 8 and 20 km with staggered beam-on cycles. Key is cost-effectively generating megawatt beams of 800 MeV protons. A superconducting ring cyclotron is being designed by L. Calabretta and his group**. This revolutionary design could find application in many ADS-related fields.
