A new DC muon beam line has been constructed at RCNP, Osaka University. The MuSIC, which has the highest muon production efficiency using superconducting solenoidal magnets, has successfully demonstrated to provide a 3 × 108 [μ+/s/μA]. In 2014, the solenoidal magnets of the MuSIC were extended by a new beam line with normal conducting magnets. The new beamline consists of beam slits, quadrupole magnets, bending magnets and a DC separator. This new beamline is designed for muon experiments such as μSR experiments and muonic X-ray measurements. To study the performance of the beams provided by the beamline, a beam test was done in December 2014 and February 2015. In this paper, a detail design of MuSIC including the new beamline and result of the beam test are written.
