| 内容記述 | The multi-ion radiotherapy with dose distribution and Liner Energy Transfer optimization is being studied at QST-NIRS. Helium, carbon, oxygen and neon ions are considered as ion species for multi-ion radiotherapy. A basic experiment using these ion beams has being carried out at the HIMAC. We have developing the new ECR ion source with all permanent magnets for multi-ion radiotherapy. Ionization gases were helium, methane, oxygen, and neon to produce He2+, C4+, O6+ and Ne7+ ions. Requirement values of beam current were 940 µA correspond to He2+, 290 µA to C4+, 330 µA to O6+, and 245 µA to Ne7+. We did some beam tests for design of compact ECR ion source at existing the 18 GHz NIRS-HEC ion source. In order to reproduce the magnetic field during experiments of NIRS-HEC, the structure of the permanent magnet was examined using the POISSON/SUPERFISH code. As a result of the calculation, it was found that a sufficient magnetic field could be obtained. Therefore, the structure of the ion source such as plasma chamber, extraction electrode, introduction of microwave and gas was injection examined according to the structure of the permanent magnet. | |||||
