  Neutrino physics focuses on huge detectors deep underground. The Sanford Lab in South Dakota will build a 300 kiloton water-Cherenkov detector 1500 meters deep, for the Long Baseline experiment (LBNE) detecting GeV neutrinos from Fermilab, 1300 km away, studying muon-neutrino oscillation for neutrino mass hierarchy and CP-violation. The DAEdALUS Collaboration plans several neutrino-production sites at closer distances up to 20 km from the 300 kT detector, producing muon antineutrinos from stopped pions. The complementarity with LBNE greatly enhances results, and enthusiasm is mounting to do both experiments. DAEdALUS needs 0.8-1 GeV accelerators with mA proton beams. Three sites at 1.5, 8 and 20 km from the 300 kT detector require several accelerators. The cost per machine must be below 1/10 of existing megawatt-class proton machines. Beyond high power and energy, beam parameters are modest. Challenges are reliability, control of beam loss and minimizing activation. Options being studied are: a compact superconducting cyclotron; a ring cyclotron accelerating (H2)+ (with stripping extraction); and a stacked cyclotron with up to 9 planes sharing the same magnet yoke and rf systems.
