Description
The MuSIC muon beamline at RCNP, University of Osaka provides a continuous muon beam with the K140 and K400 cyclotron accelerators. The employment of large capture solenoid magnets and a long cylindrical production target facilitates the utilization of high-intensity muon beams. The first muon beam was observed in 2012, and then user experiments were conducted between 2016 and 2019. However, the beamline was deactivated due to an extended shutdown for maintenance of the K140 AVF cyclotron accelerator and the failure of the solenoid magnets. Repairs to the solenoid have been completed in March 2025. The beam commissioning has recently been conducted for a novel user experiment plan.
Muon beams at MuSIC are utilized for a variety of purposes, including the analysis of muon-induced X-ray emission, nuclear physics allowing for the evaluation of muon-induced nuclear reactions, verification of semiconductor soft errors induced by cosmic-ray muons, and mSR to date. The most active application is non-destructive elemental analysis, including the study of meteorites, the investigation of archaeological materials, and other analytical studies. Moreover, a beam transport simulation has been initiated with the objective of upgrading the beamline to further enhance experimental use.
The presentation will introduce the present status of the facility and provide a brief overview of the experiments to date. It will also include plans for future improvements to the equipments and beamlines.
