Abstract：
The 1.6GeV synchrotron of China Spallation Neutron Source (CSNS) project is a Rapid Cycling Synchrotron (RCS), which accelerates a high-intensity proton beam from 80MeV to 1.6GeV at a repetition rate of 25Hz. The RCS magnet system consists of 24 dipole magnets (main dipoles), 48 quadrupole magnets (main quadrupoles), 16 sextupole magnets, some tune shift quadrupoles and corrector magnets. All the magnets are of large aperture for a high beam power
of 0.1MW, one design issue is the fringe field at pole end. And the main dipoles and main quadrupoles work at 25Hz repetition rate, the eddy current is an additional issue. In this paper the magnet design of the two kinds of main magnets will be described.
