SEOUL NATIONAL UNIVERSITY ACCELERATOR MASS SPECTROMETRY (SNU-AMS) RADIOCARBON DATE LIST I

Abstract

The accelerator mass spectrometry facility at Seoul National University (SNU-AMS) began functioning

in December 1998 and was first reported at the Vienna AMS conference in October 1999

and at the 17th International Radiocarbon Conference in Israel in June 2000. At the Vienna conference,

we reported our accelerator system (Kim et al. 2000) and details of the basic sample preparation

system (Lee et al. 2000), such as the combustion line to produce CO2; the catalytic reduction

line for the graphitization of CO2; and the pretreatment procedures for wood, charcoal, and peat

samples. The recent progress of the AMS facility (Kim et al. 2001) and the extension of the sample

pretreatment system to iron and bone samples were reported at the 17th International Radiocarbon

Conference (Cheoun et al. 2001). In the meantime, extensive testing of accuracy and reproducibility

has been carried out, and ~1000 unknown archaeological and geological samples have been measured

every year. In this report, the archaeological, geological, and environmental data carried out in

1999 are presented in terms of yr BP.
