Abstract

We designed and fabricated a sputtering source with a simple structure to extract metal beam for the RAON heavy ion accelerator. As a test material, Bi with a mass number of 209 was selected, and a beam extraction experiment was conducted. A Bi25+ beam with a current of 3 euA was extracted during the preliminary beam extraction experiment. We confirmed that impurity control and a high-power comparative experiment are necessary for future experiments.
