Abstract
Since 2001, the Center for Applied Isotope Studies at the University of Georgia has analyzed more than 10,000 samples using a compact AMS system for carbon isotope measurement. The system, manufactured by National Electrostatics Corporation, utilizes a Model 1.5SDH-1 Pelletron accelerator with a maximum terminal voltage of 0.5 MV. The source has recently been modified, doubling the count rate and improving efficiency more than 50%. Background values have reached 0.12 pMC and the precision is below 0.4 pMC for modern samples. The control and data acquisition system has also been upgraded.
