Muon设施J-PARC(Muon科学机构；MUSE)自2008年第一束以来一直在运行。从一束200kW的质子束流开始，束流强度已经达到了3×106/Muons/S，这是世界上最强的脉冲µ子束。一个2厘米厚的石墨靶可以提取四个次级µ子束。计划建设一条全新的梁线--H线。新的光束线被设计成有很大的接受度，将提供调节动量的能力，并使用Kicker磁铁和/或Wien过滤器。这条束线将为需要高统计量的实验提供强流束流，并且必须占用实验区较长的时间。
The muon facility, J-PARC (Muon Science Establishment; MUSE), has been operated since first beam in 2008. Starting with a 200 kW proton beam, the beam intensity has reached 3× 10 6/muons/s, the most intense pulsed muon beam in the world. A 2 cm thick graphite target permits the extraction of four secondary muon beams. A brand new beam line, the H line, is planned to be constructed. The new beam line is designed to have a large acceptance, will provide the ability to tune the momentum, and use a kicker magnet and/or Wien filter. This beam line will provide an intense beam for experiments that require high statistics and must occupy the experimental areas for a relatively long period.
