In FY2021 \, non-destructive analysis was carried out on samples brought back by Hay abusa2 from the asteroid Ryugu\, which are thought to preserve the element al composition of the solar system in its primordial state. \nStable opera tions have been achieved in S1 area of S-line for μSR. In addition\, a gr oup at Okayama University constructed a new experimental area\, S2\, in FY 2020 for muonium 1s-2s measurement. \nU-line\, uses electrostatic lenses t o focus low-energy muons obtained by laser ionization of thermal muonium t o produce energy-variable and high time-resolution ultra-slow pulsed muon beams for various experiments. A muon spin spectrometer for materials scie nce research using the μSR method has been installed in the U1A area\, an d is being upgraded and upgraded for the start of the inter-university use r program. The spectrometer is located on a high-voltage stage and the dep th of penetration into the sample can be controlled in the range from sub- keV to 30 keV.\nThe H line is a high-intensity muon beamline where experim ents such as high-statistics fundamental physics experiments and transmiss ion muon microscopy are planned. The first beam observed in the H1 experim ental area\, the first branch\, in January 2022.\nAt present\, the beam co mmissioning is being carried out in collaboration with several research gr oups that plan to conduct experiments at the H-line.\n\nhttps://indico.stf c.ac.uk/event/53/contributions/3688/ LOCATION:Science and Technology Campus\, University of Parma URL:https://indico.stfc.ac.uk/event/53/contributions/3688/ END:VEVENT END:VCALENDAR
