目前正在研制一台Muon直线加速器，用于用再加速的热Muon束精确测量Muon反常磁矩(g−2)和电偶极矩(EDM)。研制了一台紫外光驱动的H-−光源，用于进行介子加速实验。在加速实验之前，由于加速后的Muon强度非常低，使用该H−束流进行了光束线调试。我们成功地测量了磁刚性，这是识别加速的µ子所必需的。该H-−源可用作其他光束线的通用束源。
A muon linac is under development for the precise measurement of the muon anomalous magnetic moment (g− 2) and electric dipole moment (EDM) with a reaccelerated thermal muon beam. An H− source driven by an ultraviolet light has been developed for the muon acceleration experiment. Prior to the acceleration experiment, a beamline commissioning was performed using this H− beam, since the accelerated muon intensity is very low. We successfully measured the magnetic rigidity, which is essential for identifying the accelerated muons. This H− source is capable of utilizing as a general-purpose beam source for other beamline.
