A new approach to search for CP violation in the neutrino sector is proposed by the experiment called DAEALUS (Decay At rest Experiment for cp At Laboratory for Underground Science). DAEALUS needs three sources of neutrino fluxes, each one located at 1.5, 8 and 20 km from the underground detector. Each source has to be supplied with a proton beam with power higher than 1, 2 and 5 MW respectively. The study for a Superconducting Ring Cyclotron able to accelerate the H_2⁺ molecules and to deliver proton beam with maximum energy of 800 MeV and the required power, will be presented. Although the average power for the first 2 sites are 1 and 2 MW, the 20% duty cycle, required by the experiment, has the consequence that the peak power should stay in the range 5-10 MW and a peak current of about 4.5 mA of H_2⁺ is necessary. The description of superconducting magnetic sector simulated by the code TOSCA, the isochronous magnetic field produced and the magnetic forces acting on the coils, will be discussed. Some evaluation on the feasibility of the ring cyclotron, the advantages and problems relates with acceleration of the H_2⁺ molecules, and the main features of a injector cyclotron will be also presented.
