Tuning of the ultra slow muon beamline by utilizing ionized hydrogen

The ultra-slow muon beam is expected to be a new probe for surface and interface physics. A new beamline for the ultra-slow muon is now under construction at the J-PARC. Before transporting ultra-slow muons through the transport system, we tuned the system utilizing laser ionized hydrogen ions as ultra-slow beam. We successfully transported ions to the end of the beam line. Optimization of the beam transport system is in progress to be ready for generating the ultra-slow muon beam
