Abstract
In February 2007, a single stage AMS from the National Electrostatics Corporation (NEC) was installed at the Research School of Earth Sciences at the Australian National University. This instrument is equipped with a gas/graphite hybrid ion source allowing direct analysis of CO2 as well as traditional graphite targets. The instrument was funded by an Australian Research Council grant and by a consortium of eight universities plus the CSIRO Division of Land and Water. Its purpose is to support integrated environmental and archaeological research and access is open to the wider research community. In the first year â¼1500 samples have been analysed. A precision of â¼3â° is routinely observed. The background for processed graphite (coal, calcite, Carrera marble) is better than 45,000Â years. This paper summarizes the first year of measurements.
