A compact C-14 AMS system manufactured by the National Electrostatics Corporation has been installed at the Institute of Heavy Ion Physics, Peking University. The system is based on a Model 1.5SDH-1 Pelletron accelerator with a maximum terminal voltage of 0.6 MV. The C-14 measurement accuracy with this system is better than 0.4% and the machine background is lower than 0.03 pMC. The performance of the new system, especially the background and the delta C-13 measurements, is presented. Several important applications are also described briefly.
