| Outline of Final Research Achievements |
Nuclear physics experiment using RI beams are usually performed at large scale experimental facilities. We are studying a possibility to construct a small-scale low-cost RI beam generator, as a complementary tool for RI beam experiments. For the RI beam generator, we are developing the "gas-transport single-accelerator post-acceleration ISOL" method, utilizing advantages of a tandem electrostatic accelerator (low operation cost, capability of quickly changing beam nuclide and energy, small beam emittances, etc.). For the present method, we tested an RI production gas target tube and a negative ion source which can accept gasses. From the present test results, RI beam intensities, expected in the future, were roughly estimated. The result were 370/s for carbon-11 and 6200/s for tritium, which demonstrated the feasibility of the present method.
