In the meanwhile, a so-called second generation AMS ^<14>C apparatus (Tandetron-II AMS system) manufactured by High Voltage Engineering Europe, BV, the Netherlands has been installed successfully at CCR in 1997. Though we had experienced a lot of difficulties with the Tandetron-II just two years after its installation, we were able to start ^<14>C measurements with the machine in acceptable precision since the end of 1999. 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 suggest that accuracy of ^<14>C measurement can be as good as around 0.5% We participated the Forth International Radiocarbon Intercomparison (FIRI) program started in 1999,after its set up at the time of the 15^<th> International Radiocarbon Conference at the University of Groningen, the Netherlands, in 1997. In the FIRI program, 10 samples of different materials were distributed to 92 ^<14>C laboratories of three different ^<14>C detection methods (25 AMS labs., 18 GPC labs. and 49 LSC labs.) from 37 different countries. Our AMS group of Nagoya University is one of the 25 AMS labs. The FIRI results have been reported preliminarily at the Edinburgh workshop on March 2001. We can also get the results by the web site of Radiocarbon (www. radiocarbon. org). We briefly summarize the report in relation with our own results, which are consistent with the mean values of ^<14>C results reported from 25 AMS labs.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_9_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"第14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13
