摘要：

There is more than three standard-deviations discrepancy between measurement and theoretical prediction of the muon anomalous magnetic moment. We are going to measure the precision value of muon g-2 and search for physics beyond standard model. In addition, we can search for muon EDM which violates CP symmetry. CP violation in charged lepton sector is currently not found. We are developing the "Ultra Cold Muon Beam" instead of tertiary muon beam with electric focusing. Ultra cold muon is realized by laser ionization of muonium (bound state of a muon and an electron) from the production target. Increase of muonium yield is essential for our experimental goal; 0.1ppm statistical precision. Muonium production experiment at J-PARC MLF MUSE is planned in 2012 autumn. In this paper, we discuss the development of muonium production target and positron detector for the study.
