| 内容記述 | We proposed to apply the MLE method for determining the range of heavy ions and demonstrated the effectiveness of this method by experiments with 12C beams. We performed irradiation experiments with stable 12C ions of mono-energetic 290 MeV/u to a water, a polyethylene and a PMMA target. The theoretical ranges for 12C ions of 290 MeV/u in these targets are 160.5, 157.9 and 139.8 mm, respectively. The anihilation events from positron emitters generated by 12C ions were detected with a positron camera for 500 s just after the irradiation. To evaluate the range of 12C ions, the MLE method was applied to the annihilation gamma ray distribution. The derived ranges for the three targets were 160.6, 158.9 and 140.4 mm, respectively. Therefore, we can conclude that the range of 12C ions was determined within an accuracy of 1.0mm for all targets. |
