A muon linac development for a new muon g-2 experiment is now going on at J-PARC. Muons from the muon beam line (H-line) at the J-PARC MLF are once stopped in an silica aerojel target and room temperature muoniums are evaporated from the aerogel. They are dissociated with laser (ultra slow muons), then accelerated up to 212 MeV using a linear accelerator. As the first accelerating structure, an RFQ will be used. We are planning to use a spare RFQ of the J-PARC linac for the first acceleration test. For this acceleration test, an degraded muon beam will be used instead of the ultra slow muon sourece. In this paper, present status of this muon acceleration test using the J-PARC RFQ is presented.

Precision measurements of the muon's anomalous magnetic moment (g-2) and electric dipole moment (EDM) are one of the effective ways to test the standard model. An ultra-cold muon beam is generated from a surface muon beam by a thermal muonium production and accelerated to 300 MeV/c by a linac. The muon linac consists of an RFQ, an inter-digital IH, a Disk And Washer structure, and a disk loaded structure. The ultra-cold muons will have an extremely small momentum spread of 0.3 % with a normalized transverse emittance of around 1.5 pi mm-mrad. The design and status of the muon linac at J-PARC will be presented.
