The MuSIC (Muon Science Innovative Channel) beam line at RCNP (Research Centre for Nuclear Physics, Osaka) will be the most intense source of muons in the world. A proton beam is incident on a target and, by using a novel capture solenoid, guides the produced pions into the beam line where they subsequently decay to muons. This increased muon flux will allow more precise measurements of cLFV (charge Lepton Flavour Violation) as well as making muon beams more economically feasible. Currently the first 36$^{circ}$ of solenoid beam pipe have been completed and installed for testing with low proton current of 1nA. Measurements of the total particle flux and the muon life time were made. The measurements were taken using thin plastic scintillators coupled to MPPCs (Multi-Pixel Photon Counter) that surrounded a magnesium/copper stopping target. The scintillators were used to record which particles stopped and their subsequent decay times.
