At the J-PARC Muon Science Facility (MUSE), a new Ultra-Slow Muon beamline is being constructed to extend the SR technique from bulk material to thin lms, thus empowering a wide variety of surface and nano-science studies, and also a novel 3D imaging with the \ultra-slow muon microscope”. Ultra-slow muons will be produced by the re-acceleration of thermal muons regenerated by the laser resonant ionization of muonium atoms evaporated from
a hot tungsten foil, a method that originated from the Meson Science Laboratory at KEK. The design parameters, construction status and initial beam commissioning are reported.
