Description
In order to facilitate specialized applications involving broad-band white light neutron and muon sources, the China Spallation Neutron Source (CSNS) plans to construct a Fixed-Field Alternating Gradient (FFAG) accelerator. With the 300 MeV injector of the CSNS-II, the FFAG accelerator will increase the beam energy from 300 MeV to 600 MeV and then to bombard a target, thereby generating the requisite copious neutrons for the applications. This paper will provide a comprehensive overview of the physics design of the FFAG accelerator, such as the beam injection and extraction, Lattice, beam dynamics, error correction, beam optics, beam collimation, beam loss control, nonlinear studies, and so on. Finally, a preliminary design proposal for the CSNS-II FFAG accelerator will be present.
