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.
