The J-PARC muon facility is a pulsed muon beam facility located in the Materials and Life Science Experimental Facility.
It has four muon beamlines and seven experimental areas in operation, and a new beamline (H-line) and two new experimental areas (H1 and S2 area) started operation in January 2022.
They are used for fundamental physics experiments, such as precise measurements of muoniums, and a search for $\mu$-e conversion.
Further extension of the H-line is ongoing to develop a novel low emittance muon beam for a muon $g-2$/EDM experiment and a muon transmission microscope.
For more future planning, the conceptual design of a new target station, which allows for over 50 times more intense muons, is underway.
