AbstractA 3MV multi-element accelerator mass spectrometer (AMS) has been installed in Xian, China, and preliminary tests have been completed. The results of both background and precision tests for 4 nuclides are 3.1 x 10^-16, 0.2% (14C); 1.8 x 10^-14, 1.4% (10Be); 2.3 x 10^-15, 1.14% (26Al); and 2.0 x 10^-14, 1.75% (129I). The unique features of this facility are the newly developed ion source accepting solid and CO2 samples; the specially designed low-energy injector, including a beam blanking unit and Q-snout; the acceleration tube structure with the combined magnetic and electrostatic suppression; and the function of the slit stabilization in the post-acceleration system. These features are discussed in terms of the end-users point of view.
