Multi-nuclide AMS performances at MALT

Measurements of cross sections for production of light nuclides by 300MeV proton bombardment of Cu and Y

“…The rest of the procedure is the same as that described in the previous paragraph. The isotopic ratios of 10 Be/ 9 Be and 26 Al/ 27 Al in the Y target were determined by AMS at MALT [12]. The isotopic ratios of both AMS measurements were normalized using the same 10 Be, 26 Al, and 36 Cl AMS standards [13][14][15].…”

Trace element variations in fossil corals from Tahiti collected by IODP Expedition 310: Reconstruction of marine environments during the last deglaciation (15 to 9 ka)

“…Radiocarbon dating on corals were conducted under the protocol described in Yokoyama et al (2007b) and measured at the University of Tokyo (Matsuzaki et al, 2007). It is well known that the last glacial radiocarbon age calibrations have some issues (eg., Esat and Yokoyama, 2008), yet more robust calibration protocol is available during the deglaciation.…”

Quantitative determination of long-term erosion rates of weathered granitic soil surfaces in western Abukuma, Japan using cosmogenic 10Be and 26Al depth profile

“…The purified quartz samples were dissolved with HF and were spiked with a Be carrier (~0.4 mg). Aliquots for Be and Al were separated by a series of column chromatography and then oxidized for AMS measurements ( 10 Be/ 9 Be and 26 Al/ 27 Al) at The University of Tokyo following the method of Matsuzaki et al (2007). Standard materials of KNB5-1 and KN5-1 are used for AMS measurements of Be and Al, respectively (Nishiizumi et al, 2007).…”
