Applications of Imaging Plates to the Study of Positron and

A muon beam intensity distribution perpendicular to the beam has been obtained using imaging plates which are commonly used in X-ray science, transmission electron microscopy, bio and medical analysis. The resolution of imaging plates depends on the resolution of an imaging plate reader. We have used BAS-TR2025 imaging plates and Bio- Imaging Analyzer BAS-2500 or BAS-3000. The positional resolution is 50 μm x 50 μm. When the beam is one kind, the coincidence measurement is not necessary so that the muon distribution perpendicular to the beam is taken in a very short time and the spatial resolution is 50 μm x 50 μm. Such a resolution cannot be obtained by 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 μm x 10 μm. Such intensity resolution of muon beams could not be imagined without using imaging plates. Transmission muon images obtained are also presented. This can be used as a non-destructive test.
