Description

High-speed charged particles (such as electrons) are scattered in matter by the electric field of the atomic nucleus producing the Bremsstrahlung X-rays (light). Since the efficiency of Bremsstrahlung is inversely proportional to the square of the mass, in principle, $\mu^{\pm}$ which is 200 times heavier than an electron, can produce 40000 times less Bremsstrahlung than an electron. On the other hand, the fast protons (9 times heavier than muons) undergo nuclear reactions in matter and are transformed into pions and K-mesons. Although $\mu^{\pm}$ has a mass between that of an electron and a proton, it neither change into other particles nor easily scattered. This is the physical reason for their excellent permeability.
The accelerator muons are a million times more intense than cosmic muons. These muons will be used for 3D imaging of thick materials as well as the 3D distribution of electromagnetic fields inside the objects.
At the symposium we are going to report the current status of J-PARC, Muon Science Establishment (MUSE) and in particular, activity on the 3D muon imaging at J-PARC to improve special resolution.
