摘　　要：Purpose The Experimental Muon Source(EMuS)project proposed at the China Spallation Neutron Source(CSNS)is a facility for muon applications and neutrino physics research.The EMuS target station adopts a superconducting solenoid scheme to meet the requirements of muon and pion capture.The capture solenoid consists of four solenoids with different apertures to meet the requirements of the central magnetic field up to 5T.Due to the high-irradiation environment,the capture solenoid adopts aluminum-stabilized Rutherford cable winding scheme to reduce the heat deposition on the coil.The magnet design considers the degradation of properties of aluminum stabilizer after continuous neutral irradiation.Due to the characteristics of the coil material,the magnet has different steady-state thermal characteristics and quench performance during different operating periods.Method and result Through the analysis of the operating characteristics,this paper proposes the design of the magnet structure and quench protection scheme.According to the simulation,the current design can satisfy a continous operating time of 200 days per year.
