The Institute of Earth Environment of the Chinese Academy of Sciences and Xi'an Jiaotong University have jointly created an AMS center and acquired from HVEE a 3MV multi-element (¹⁰Be, ¹⁴C, ²⁶Al and ¹²⁹I) AMS system. The main focus of the Xi'an AMS center will be earth environmental studies, archeology and biomedical research. The AMS system chosen is the fourth production of bouncer-based AMS systems by HVEE. It is currently under installation and test at Xi'an, and is expected to be fully operational in early 2006. The general layout of this system, as well as some specific features and possible improvements, will be described from an end-user's point of view. During the system's planning stage, we once suggested a unique low energy spectrometer layout, which would accommodate injection modes of both recombinator for high precision ¹⁴C measurement, and sequential bouncer for general multi-element applications. This will also be described briefly.
