While conventional muon beam can be used to investigate rather small samples, there is a strong requirement for still lower energy ultra-slow muons that can be stopped near sample surfaces, in thin films and near multi-layer interfaces. A number of cooling techniques have been suggested to produce ultra-slow muons, such as two-photon laser resonant ionization of muonium atoms and energy moderation of muons in a thin foil-degrader. In this work, in close collaboration with the Muon Science Establishment (MUSE) at Material and Life science experimental Facility of J-PARC, we provide a brief overview of the primary muon production target, where two of the four associated secondary beam transport lines which are dedicated to experiments employing the ultra-slow muons. In particular, we present the results for simulation of the ultra-slow muon production with tunable energies in the range of energies between 5.65 and 30 keV based on the simple energy moderation of transported muon beam in thin foil-degrader. In addition, we discuss accelerator optics design and beam acceleration simulation results for muon microscopy, which can provide a microbeam.
