Spin-polarized ultra-low-energy muons (LE-μ + ) with energies in eV–keV range provide a sensitive magnetic microprobe for studying near-surface regions, thin-film samples, multi-layered materials, etc. with depth resolution on a nanometer scale. Yet, worldwide there is currently only one (continuous) source of low-energy muons that is routinely used for such measurements. A pulsed source with many unique parameters (such as low-energy resolution of ∼14eV, time resolution of 7ns, low background and spot size of just 4mm) has been demonstrated at RIKEN-RAL muon facility at ISIS, but its use is limited by a rate of only 15μ + /s. The method of low-energy muon generation is based on a resonant laser ionization of thermal energy muonium and is ideally suited for a pulsed muon source such as J-PARC MUSE, since the pulse structure of the generated LE-μ + is then determined by the laser pulse duration. The double pulse structure of the surface muon beam can, therefore, be converted to a single LE-μ + pulse with a pulse duration that can be as short as 1ns and can also be externally triggered. J-PARC is designed to deliver surface muon beam with rates up to 4×10 8 μ + /s and direct transfer of the same laser technology from RIKEN-RAL to J-PARC would provide a LE-μ + beam with rates comparable to the existing continuous LE-μ + beam at PSI (∼10 4 LE-μ + /s). An improvement in the laser pulse energy could lead to a higher efficiency and higher rates up to 10 6 LE-μ + /s may be possible. Construction of an intense LE-μ + beamline at J-PARC MUSE would open up the possibility to do routine depth-dependent μSR measurements with thin film samples, with the muon implantation depth as low as 1nm. In addition, the unique capability to synchronize the muon implantation with the sample excitation (e.g. by another laser or rf pulse) would allow to carry out pump-probe-type experiments.
