[18a-D411-10] Magnetic field imaging by cosmic-ray muons (Magic-μ)
– Simulation of magnetic fields in scattering muography –
Keywords:magnetic field muography, cosmic-ray muon, scattering muography
Cosmic-ray muons provide a powerful tool for imaging and inspection of various targets,
and applications are evolving every year. The imaging technique is known as muography, and
there are two different techniques for using these high-energy particles: scattering muography
and absorption muography. Of all the applications of cosmic-ray muons, the most interesting
to governments is the use of cosmic-ray muons in security and cargo inspection, where muons
can penetrate to the thickness of 100 cm of steel and detect shielded high-z material and
provide a 3D image of the materials in the inspection area.
Considering the Lorentz force, the force exerted on a charged particle moving through an
electric field and a magnetic field, our group proposed MAGnetic field Imaging by Cosmic-
ray Muon (Magic-μ), since muons are also charged particles. We have considered
several possible applications for this technique, such as imaging the strong magnetic field of
fusion reactors or accelerators. In this study, we focus on the simulation of magnetic fields
in scattering muography, where the position of muons before and after crossing the region of
interest is recorded with position-sensitive detectors. To study the effect of magnetic fields,
the simulation was performed in two steps. First, the image of the target was obtained using
the Point of Closest Approach (POCA) reconstruction algorithm, and then the target was
placed in a dipole magnetic field region with different magnetic flux densities. The results
demonstrate that the image of the target in the magnetic field is different from the original
image and it may be necessary for inspection systems using cosmic-ray muons to verify that
there is a magnet in the inspection region.
