Outline of Final Research Achievements

This study aimed to development of a beam monitor for measurement of intensity distribution of hundreds MeV ion microbeam. Specifically, the beam intensity was measured by imaging devices covered with scintillator. Calcium fluoride was selected as scintillator because it has the high degree of transparency and luminance, and little damage by beam irradiation. CCD and CMOS were used as imaging devices. As a result of irradiation experiment with 260 MeV neon beam, it was possible for the monitor to detect irradiation positions of the beams of a few counts per second with the spatial resolution of less than 7 μm in the case of CCD. Furthermore, the beams of hundreds counts per second were detectable in the case of COMS.
