| 内容記述 | In ion beam cancer therapy, it is generally essential for a scanning-irradiation method and a rotating gantry system to deliver a circular beam profile with a Gaussian distribution. A slow beam extraction method utilized in a synchrotron ring, however, can not deliver a beam with a Gaussian distribution in the horizontal phase space, because of its extraction mechanism. Thus, we have proposed a thin scatterer method in order to compensate for the phase-space distribution of a slowly extracted beam, although the emittance is slightly enlarged by scattering. As a result of particle tracking, we verified that the proposed method could change an asymmetric distribution to a Gaussian one in the horizontal phase space and realize a symmetric beam condition for the rotating gantry. |
