A New 1MV AMS Facility at KIGAM

Abstract

A 1MV AMS was installed in KIGAM (Korea Institute of Geoscience and Mineral Resources). After 4 months of installation, the AMS started normal operation from January 2008. This multi-element AMS was developed by HVEE to measure 14 C, 10 Be, and 26 Al. The results of an acceptance test demonstrate that this machine is capable of routine 14 C age dating and of measurements of other radioisotopes in terms of accuracy and precision as well as the background level. After installation, an investigation aimed at determining the stable operating conditions was conducted, and background levels were determined to be as low as 10 –15 for 14 C and 10 –14 for 10 Be and 26 Al.
