High Power Cyclotrons for Neutrino Experiments

The study of the neutrino properties using decay-at-rest beam requires high intensity proton beams able to produce optimal reaction channels. In particular, the MIT experiments named DAEδALUS (Decay At rest Experiment for δcp At Laboratory for Underground Science) and IsoDAR (Isotope Decay At Rest) require a proton beam current up to 10 mA each. High power cyclotrons able to produce proton beams at the maximum energies of 60 MeV (IsoDAR) and 800 MeV (DAEALUS) are under investigation: the critical points and the proposed solutions are discussed here.
