- Measurement of IAEA <14>^C standard materials with the 2nd Tandetron AMS machine at Nagoya University : estimates of precision and accuracy
この論文をさがす
説明
A Tandetron accelerator mass spectrometer, an apparatus dedicated to high sensitivity radiocarbon (^<14>C) measurements, manufactured by General Ionex Corporation, USA, has been used since 1983 to measure the ^<14>C concentrations of environmental samples as well as ^<14>C dates of geological and archaeological materials, at the Center for Chronological Research (CCR), Nagoya University. A so-called second generation AMS ^<14>C apparatus manufactured by High Voltage Engineering Europe, BV, the Netherlands has been installed at CCR in 1997 and has been tested of its performance on ^<14>C measurements. The authors present here a brief review of the present performance and status of the Tandetron-I and Tandetron-II AMS systems. The ^<14>C measurement error (one sigma error) of the Tandetron-II is around +/-20-+/-40 years, which is clearly smaller than that of the Tandetron-I (around+/-50-+/-90 years). In addition, the reproducibility tests of ^<14>C measurements for the IAEA C1-C8 ^<14>C standards suggests that accuracy of ^<14>C measurement can be as good as around 0.5%.
