Abstract: High intense muons are required by many applications in muon science. A large acceptance channel for surface muons was designed at China Spallation Neutron Source (CSNS) using a superconducting solenoid and an internal target, which can provide a large solid angle to collect intense surface muons. Compared to conventional separate target and collection system based on quadrupole magnets, a superconducting solenoid with large aperture can collect two orders larger of surface muons. This device was simulated by Geant4 and G4beamline. By analyzing the surface muon production ratio produced by the process that protons bombard four different materials, we chose the graphite as the target material. Then comparing the intensity of surface muon by different angles between the axis of the capture solenoids and the proton beam line, we proposed the capture and transport solenoid system with higher muon production ratio. Finally, the yield of surface muon at the exit of decay solenoid can be up to 108/s.
