摘要The China Spallation Neutron Source (CSNS) accelerators consist of an 80MeV proton linac, and a 1.6GeV rapid cycling synchrotron. The ring accumulates 1.88x 10(13) protons via H- stripping injection in the phase CSNS- I. The injected beam is painted into a large transverse phase space to alleviate space-charge effects. The uniformity of the beam emittance after the injection is important in reducing the tune shift/spread due to the space-charge effects. The paper introduces three parameters to evaluate the uniformity of a beam distribution. To control emittance growth and reduce halo generation, different painting schemes have been compared by using the 3D simulation code ORBIT. The detailed studies on painting schemes and the dependence on the lattice tune, the injection peak current, and chopping rate are also presented.
