LET INDEPENDENCE PEAK DETECTION METHOD, DOSE DISTRIBUTION MEASUREMENT METHOD, AND DETERMINATION METHOD OF THERMAL FLUORESCENT CHARACTERISTIC

摘要

PROBLEM TO BE SOLVED: To provide a determination method that can find the dose distribution of a particle beam and determine the thermal fluorescent characteristic of a thermal phosphor, by establishing a method of measuring the LET dependence accurately and simply (method of detecting a peak having no dependence).SOLUTION: An LET independence peak detection method detects an independence peak having no LET dependence, by a process of irradiating a thermal phosphor with a particle beam, heating the thermal phosphor after the irradiation at a predetermined temperature increase rate, and measuring the thermal fluorescent characteristic, or a process of measuring the thermal fluorescent characteristic using only light of a specific wavelength.SELECTED DRAWING: Figure 1
