  Neutrino physics is a forefront topic of today's research. Large detectors
installed underground study neutrino properties using neutrino beams from muons
decaying in flight. DAEdALUS looks at neutrinos from stopped muons, "decay at
rest" (DAR) neutrinos. The DAR neutrino spectrum has effectively no electron
antineutrinos (essentially all pi- are absorbed), so a detector with free
protons is sensitive to appearance of nu-e-bar oscillating from nu-mu-bar via
inverse-beta-decay (IBD). Oscillations are studied using sources relatively
near the detector, but which explore the same physics as the high-energy
neutrino beams from Long Baseline experiments. As the DAR spectrum is fixed,
the baseline is varied: plans call for 3 accelerator-based neutrino sources at
1.5, 8 and 20 km with staggered beam-on times. Compact, cost-effective
superconducting ring cyclotrons accelerating molecular hydrogen ions (H2+) to
800 MeV/n with stripping extraction are being designed by L. Calabretta and his
group. This revolutionary design could find application in many ADS-related
fields.
