The JAEA-AMS-TONO facility was established in 1997 at the Tono Geoscience Center, Japan Atomic Energy Agency. Our AMS system has been made available for $$^{14}$$C- and $$^{10}$$Be-AMS. At present, the development of $$^{26}$$Al-AMS has been conducted to enhance the capability for multi-nuclide AMS. In this presentation, we report the progress on multi nuclide AMS in addition to the status of our facility.

Steady progress has been made in the development of a multi-nuclide AMS system for measurement of rare radionuclides ($$^{10}$$Be, $$^{14}$$C, and $$^{26}$$Al) to apply geochronological dating methods. In this article we will report the current status of the JAEA-AMS-TONO.

Cosmogenic nuclides of $$^{10}$$Be and $$^{26}$$Al are used for studies such as estimation of exposure age and erosion rate of rock. In order to measure traces of $$^{10}$$Be and $$^{26}$$Al by accelerator mass spectrometry (AMS) in these studies, reagents with low levels of $$^{10}$$Be and $$^{26}$$Al are needed. In this study, ratios of $$^{10}$$Be/$$^{9}$$Be or $$^{26}$$Al/$$^{27}$$Al in several reagents were compared. The reagents were oxides for evaluation of blank in measurement and standard solutions for atomic absorption spectrometry (AAS) or inductively coupled plasma optical emission / mass spectrometry (ICP) for carrier and evaluation of process blank. The ratios were measured in JAEA-AMS-TONO. The ratios of $$^{10}$$Be/$$^{9}$$Be in the Be oxides and the Be standard solutions were approximately 10$$^{-14}$$$$sim$$10$$^{-15}$$ levels. The Be Standard solutions for AAS and ICP supplied by Merck had lower ratios of $$^{10}$$Be/$$^{9}$$Be than those supplied by Wako and Kanto chemical.

The JAEA-AMS-TONO facility at the Tono Geosciences Center, Japan Atomic Energy Agency has an AMS system. Since November 2014, the Toki Research Institute of Isotope Geology and Geochronology has been established at the Center, developing multiple radiometric dating of geological samples and the JAEA-AMS-TONO is the main facility in the institute. The facility has routinely analyzed $$^{14}$$C and $$^{10}$$Be for investigations into deep underground environments and has performed test measurement of $$^{26}$$Al. In this presentation, we report our present status.
