A new compact AMS system at Peking University

A compact 14C 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 14C 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 δ13C measurements, is presented. Several important applications are also described briefly.
