Outline of Final Research Achievements |
We have developed an electron-attachment-type negative fullerene (C60) ion source to intensify the incident negative ion beam current to a tandem accelerator. In this ion source, the sublimated C60 is negatively ionized by capturing a low-energy electron. An ion source with a filament as an electron source was constructed, and negative ion beam current extracted from the ion source was measured. In the result, the intensity of the negative C60 ion beam by the ion source became ten thousand times higher than that by the cesium sputter type ion source.
