Abstract

In order to improve the accuracy of charged-particle radiation therapy, the beam energy was measured precisely using a TOF-system, and the range using a counter telescope system. A Si detector and a Ge detector were used to estimate the range straggling as a $\Delta$E and an E detector, respectively, because they have good energy resolution and the output pulse heights don't depend on the atomic number of detected particles. The results were compared with the theoretical values by a calculation code.
