| 内容記述 | We proposed application of the maximum likelihood estimation (MLE) method for determination of the range of incident ions in a target. To demonstrate the effectiveness of the method with experiments, we performed irradiation experiments with 4 kinds of stable ion beams to a gelatinous water, a polyethylene, and a PMMA target. The mean ranges were measured with a parallel plate ion chamber. The annihilation events from the positron emitters generated through the reactions of incident ions with target unclei were detected with a positron camera for 500 s just after the irradiation. To evaluate the range of 4 kinds of beams, the MLE method was applied to the annihilation gamma ray distribution. For all the combinations of incident beams and targets, the range of incident ions could by determined within an accuracy on 1.5 mm. | |||||
