Micrometer-sized particles condense in the atmosphere of exploding stars and their isotopic composition records the nucleosynthesis processes in the star. These particles, called stardust or presolar grains, formed before the formation of our sun and solar system. These stardust grains were ultimately incorporated in the cloud of matter that our solar system formed from. Because isotopic...

For taking out nuclear fuel debris safely, there is a strong need for analysis methods of debris precisely. The most important thing in the debris analysis is isotope ratio of a certain elements, because the ratio is closely related to both the accident progress and the state of debris. Secondary ion mass spectrometry (SIMS) is a candidate for the analysis. However, isobaric interferences...

One of the strengths of Resonance Ionization Mass Spectrometry (RIMS) is its selectivity, that is the ability to ionize only one element in a sample containing many different elements and thereby eliminating the need for chemical purification prior to analysis. However, in cases where backgrounds are unavoidable, such as ultra-trace analysis or when overwhelming excesses of isobaric atoms are...
