✦ Synopsis

A muon beam intensity distribution perpendicular to the beam has been obtained using imaging plates that are commonly used in X-ray science, medical analysis, and transmission electron microscopy. The resolution of the imaging plates depends on the resolution of the imaging plate reader. We have used BAS-TR2025 imaging plates and a Bio-Imaging Analyzer (BAS-2500 or BAS-3000). The positional resolution is 50 mm  50 mm. When the beam is one kind, because a coincidence measurement is not necessary, the muon distribution perpendicular to the beam is taken in a very short time, and the spatial resolution is 50 mm  50 mm. Such a resolution cannot be obtained by the usual muon measuring method. This is quite convenient to adjust muon beams. When FLA-8000 or FLA-9000 is used, the resolution can be improved to 10 mm  10 mm. Such an intensity resolution of muon beams could not be imagined without using imaging plates. Obtained transmission muon images are also presented. This can be used as a non-destructive test.
