| Outline of Final Research Achievements |
The final goal of this study is to achieve the isotopic analyses with high precision for multiple elements, base on the customizing the ECRIS-MS, which was developed as a new mass spectrometry in RIKEN. The development of the system has been carried out as the following steps: 1. We customized the detection system as the multi-collector system (using a mobile slit and large faraday-cup). 2. The sputtering and the laser-ablation system were equipped to sample introduction mechanism of the ion source. 3. Mo isotope ratios were measured for standard materials to make sure the abundance sensitivity and precision. This system is being applied to the isotopic examination on the planetary materials and will be the basic system for establishing the isotopic imaging system as the next step.
