Muons can gain penetrative power as their energy increase, though electrons above 1 MeV start to trigger electromagnetic showers and protons above 1 GeV cause nuclear reactions. Muons accelerated up to about 5 MeV are able to penetrate a living cell (~ 10 um), which is impossible with ultra-high voltage (1 MeV) electron microscopes. In order to accelerate muons, efficient acceleration is necessary because the lifetime of muons is only 2.2 us. In addition, it is important to accelerate muons without increasing their energy dispersion. A cyclotron with a flat-top acceleration system is the best suited for the transmission muon microscope and is being developed at the J-PARC muon facility (MUSE). In this poster, the transmission muon microscope project and the development of the muon cyclotron will be presented.
