| Outline of Final Research Achievements |
A new method of high-purity radioactive ion beam acceleration by a FFAG accelerator has been proposed. Development of the method using the FFAG accelerator in Kyushu University has been carried out. To ensure large acceptance of the FFAG, magnetic field correction coil of pole surface type has been designed and its prototype has been tested. Acceleration of radioactive 16N produced by the d(15N,16N)p reaction using a 15N beam derived from the tandem accelerator is planned to be demonstrated after the completion of the fabrication of pole surface coils for 12 cells of the magnets. The beta-delayed alpha spectrum from 16N reliable enough for the determination of the astrophysical nuclear reaction rate of 12C+α is expected to be obtained by the realization of high-purity 16N beam applying the proposed method.
