Description
Preparations of a new experiment which aims to measure the muon’s anomalous magnetic moment (g−2) and its electric dipole moment (EDM) at the J-PARC muon facility at MLF, MUSE, are underway.
Apart from conventional experimental method as E821(BNL) or E989(FNAL), dedicated muon beam line, we have developed a brand-new experimental method, and we expect the sensitivity goal is 0.46 parts per million (ppm) in the begining (~2028), aiming for 0.1 ppm as a ultimate goal.
In this presentation, overview of new challenges of very low-emittance muon beam line, beam storage method in MRI-sized storage magnet and tracking detector which realize reconstruction of muon beam's motion in the precisely adjusted magnetic field, as well as a current status of beam line construction.
