Abstract :
A new beamline for a fundamental physics experiment is under construction at BL05 port in the Materials and Life Science Facility (MLF) at Japan Proton Accelerator Research Complex (J-PARC); this beamline is designed using novel techniques of neutron optics and it is termed “Neutron Optics and Physics.” The beam from the moderator is deflected by multi-channel supermirrors and split into three branches for individual experiments. In this study, we have optimized the design of the beam optics and shields using the Monte Carlo simulation package PHITS. The neutron fluxes of beams are expected to be 9.2×105 /cm2/μstr/s/MW, 1.2×109 /cm2/s/MW, and 4.0×108 /cm2/s/MW, with polarization of 99.8%.
