フェムト同位体分析のための加速器質量分析システムの開発

Accelerator mass spectrometry (AMS) is a mass analysis technique making use of tandem accelerators and high-charge states for determination of ultra-low isotopic ratios from 10⁻¹⁰ to 10⁻¹⁵. The utility of AMS is not limited to ¹⁴C, many other isotopes such as ¹⁰Be, ²⁶Al, ³⁶Cl, ⁴¹Ca and ¹²⁹I are suitable to analyze.The new-generation 6 MV Pelletron tandem accelerator was designed and constructed for the high-sensitivity multi-nuclide AMS at the University of Tsukuba. In this presentation, we report AMS facilities and detection techniques for femto-level isotope analysis.
