Study of Superconducting Curved Solenoids for a High Intensity Muon Beam Line

A study of superconducting curved solenoids have been carried out for a high intensity muon beamline at JPARC project at KEK. The curved solenoid is designed with 6 segmented short solenoids combined with tapered spacers in series. A pair of model coils were successfully developed and assembled with the tapered spacer to demonstrate the technical concept and the practical assembly. The cool down and excitation tests were successfully carried out. The design and test results are discussed.
