The J-PARC E34 experiment aims to measure g-2 with a precision of 0.1 ppm and search for EDM with a sensitivity to 10-{-21} e· cm with high intensity proton beam at J-PARC and a novel technique of making a muon beam with small emittance (the ultra-cold muon beam). The ultra-cold muon beam is generated from a surface muon beam by the thermal muonium (30 meV) production followed by the laser ionization, and acceleration to 212 MeV or 300 MeV/c by the muon dedicated LINAC.

Precision measurements of the muon's anomalous magnetic moment (g-2) and electric dipole moment (EDM) are effective ways to cast light on beyond the standard model of elementary particle physics. The J-PARC E34 experiment aims to measure g-2 with a precision of 0.1 ppm and search for EDM with a sensitivity to 10-{-21} e· cm with high intensity proton beam at J-PARC and a novel technique of making a muon beam with small emittance (the ultra-cold muon beam). The ultra-cold muon beam is generated from a surface muon beam by the thermal muonium (30 meV) production followed by the laser ionization, and acceleration to 212 MeV or 300 MeV/c by the muon dedicated LINAC. The muon LINAC consists of RFQ, inter-digital IH, Disk And Washer (DAW) coupled cell and disk loaded structure. The ultra-cold muons will have an extremely small transverse momentum spread of less than 1 % with a normalized transverse emittance of around 1.5 pi mm-mrad. The muon acceleration to 300 MeV/c will be the first case in the world and it will be one of the base technologies of future accelerator programs. In this talk, design and status of the muon LINAC will be reported.
