| Outline of Final Research Achievements |
Ultra-high sensitivity analysis of presolar grains that predate the formation of our solar system is expected to provide important information in tracing a history of the solar system. However, because the analysis of presolar grains was very difficult, the development of analysis method using the most advanced equipment was needed.
In this study, I succeeded in development of elemental technologies for applying the analysis of presolar grains by the most advanced equipment “LIMAS”. These results were applied to analyze space samples and semiconductors. Based on these results, it is expected that the development of analysis method for tracing a history of the solar system will advance in future.
