Abstract

Design studies, for accelerator modules based on an injector cyclotron and a superconducting ring cyclotron able to accelerate H2+_2^+ molecules, are presented. H2+_2^+ molecules are stripped by a foil creating a proton beam, with a maximum energy of 800 MeV and a beam power of 8 MW (CW). This beam would be sent to a beam dump where neutrinos would be produced from pion and muon decays at rest for the Decay At rest Experiment for δCP\delta_{CP} At the Laboratory for Underground Science - DAEδ\deltaALUS. We are discussing the advantage of H2+_2^+ molecules for acceleration and present precise beam dynamics simulations w.r.t. extraction and beam losses. In general, beam losses are one of the most challenging parts in such a high power cyclotron design and must be addressed very early on in the design. We are also addressing H2+_2^+ dissociation and the stripping process, two other characteristic challenges in the DAEδ\deltaALUS design.
