| 内容記述 | National Institute of Radiological Sciences (NIRS) promotes multiple ion therapies that form LET and dose distribution with ideal relative biological effectiveness in cancer treatment by irradiating several types of ions to the target. We are developing a compact ECR ion source of all permanent magnets that produces four ions (He2+, C4+, O3+, Ne7+) used in multiple ion therapy. We produced four ions with NIRS-HEC in a fixed magnetic field. As a result, it was obtained ion beam with sufficient intensity for multi-ion treatment. At present, there is a request of high energy beams for biological/physical experiments in addition to therapeutic use in heavy ion radiotherapy facilities. Also, considering cost reduction of the injector, it is necessary to produce ions other than carbon in the ion source and to produce an ion beam having a higher charge than that during treatment supply. Therefore, it is confirmed whether the new ion source can be applied to applications other than treatment supply. We performed C4+ and C5+ production tests in a fixed magnetic field with NIRS-HEC. As a result of using two gases and afterglow tuning, it was obtained that sufficient ion beam of 800 μA for C4+ and 500 μA for C5+. | |||||
