在J-PARC μ子设施（MUSE）上，新的光束线最近开始运行。h线是一种用于基础物理实验的高强度脉冲介子光束线。2022年1月，h线的第一束光束被送到了它的第一个分支（H1区），在那里将进行μ-e超精细结构的精确测量和μ-e转换的研究。进一步扩展h线第二分支用于μ子g-2/EDM实验和透射μ子显微镜项目也在进行中。此外，在2021财年，开放了表面μ子光束线的第二条分支（s线的S2区域）用于μ子1S-2S光谱实验。本文介绍了J-PARC介子设施的最新升级和现状，并对其发展前景进行了展望。
At the J-PARC muon facility (MUSE), new beamlines started operation recently. H-line is a high-intensity pulsed muon beamline for fundamental physics experiments. The first beam of the H-line was delivered to its first branch (H1 area) in January 2022, where a precise measurement of the muonium hyperfine structure and a search for μ-e conversion will be conducted. Further extension of the second branch of the H-line for a muon g-2/EDM experiment and a transmission muon microscope project is also ongoing. In addition, the second branch of the surface muon beamline (S2 area of the S-line) was opened for a muonium 1S-2S spectroscopy experiment in FY2021. In this paper, the recent upgrade and present status of the J-PARC muon facility and its prospects are presented.
