Detection of cosmogenic nuclides by accelerator mass spectrometry and applications for geochemical research

Abstract

Accelerator mass spectrometry is a method for detecting nuclides by accelerating to MeV energy region using an accelerator, and then separating from interfering isobar. The 6 MV tandem accelerator mass spectrometer enables highly sensitive detection of femto-isotope levels for nuclides such as Be-10, C-14, Al-26, Cl-36, Ca-41 and I-129. In this presentation, the latest AMS equipment for multi-nuclide measurement will be introduced. In addition, I report on the progress of the detection technology for cosmogenic nuclides and the application to geochemical research.
