This report provides a first design for H2+ accelerators as the DAEdALUS neutrino sources. A description of all aspects of the system, from the ion source to the extracted beam, is provided. The analysis provides a first proof of principle of a full
cyclotron system which can provide the necessary beam power for the CP violation search proposed by the DAEdALUS Collaboration.
A new approach to search for CP violation in the neutrino sector [1,2] is proposed by the experiment called DAE{delta}ALUS (Decay At rest Experiment for {delta}cp At Laboratory for Underground Science). DAE{delta}ALUS needs three sources of neutrino
fluxes, each one located at 1.5, 8 and 20 km from the underground detector. Here we present the study for a Superconducting Ring Cyclotron able to accelerate the H2+ molecules and to deliver proton beam with maximum energy of 800 MeV and the required high power. The magnetic field produced by the proposed superconducting magnetic sector, simulated by the code TOSCA, the isochronous magnetic field, some preliminary feature on the beam dynamic and the magnetic forces acting on the coils are here presented.
A Multi Megawatt Cyclotron complex able to accelerate H2+ to 800 MeV/amu is under study. It consists of an injector cyclotron able to accelerate the injected beam up to 50 MeV/n and of a booster ring made of 8 magnetic sectors and 8 RF cavities. The
magnetic field and the forces on the superconducting coils are evaluated using the 3-D code OPERA. The injection and extraction trajectories are evaluated using the well tested codes developed by the MSU group in the 80s. The advantages to accelerate H2+ are described and preliminary evaluations on the feasibility and expected problems to build the injector cyclotron and the ring booster are here presented.
