 note = {A Tandetrno accelerator mass spectrometer (AMS), an apparatus dedicated to radiocarbon (^<14>C) measurements with high sensitivity, manufactured by General Ionex Corporation, USA, has been used since 1983 to measure ^<14gt;C concentrations of environmental samples as well as ^<14>C dates of geological and archeological materials at the Dating and Materials Research Center (DMRC), Nagoya University. No serious problem has occurred with the machine, which resulted in that 770 samples were measured in 1997,and totally 7,371 samples in various fields have been measured since the installation of the machine. Though the Tandetron AMS has been operated intensively, the number of samples analyzed annually is rather limited to several hundreds which is far smaller than the number of samples brought to the DMRC by many users from various research fields, mainly owing to lower negative current intensity from an ion source (HICONEX-844,modified for loading 18 targets at a time), as well as a rather low throughput of the total system. We could have fortunately introduced a new-generation Tandetron which is manufactured by High Voltage Engineering Europe (HVEE) BV, the Netherlands. Two sets of similar HVEE AMS system have been installed successfully at the University of Groningen, Holland, and at the University of Christian-Albrechts, Kiel, Germany. They have already shown excellent performances in carbon-isotope-ratio measurments : reproducibility of ^<12>C/^<13>C ratio as ±0.1%; error and reproducibility of ^<14>C/^<12>C ratio as ±0.15%-±0.22% and ±0.3%, respectively. We are planning to perform high accuracy and high precision ^<14>C dating of mainly cultural property materials of historical age, archeological and geological samples, by using the new-generation machine., タンデトロン加速器質量分析計業績報告 Summaries of Researches Using AMS 1997 (平成9)年度},
