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%., 第13回名古屋大学タンデトロン加速器質量分析計シンポジウム(平成12 (2000)年度)報告 名古屋大学タンデトロン加速器質量分析計第2号機の研究成果と利用計画}, pages = {35--43}, title = {名古屋大学タンデトロン2号機による<14>^C濃度既知の標準試料(IAEA C1-C8)の測定 : 測定精度と正確度の検定}, volume = {12}, year = {2001} }
