Progress in XCAMS at Tianjin University

A compact 14C AMS system extended for 10Be and 26Al (XCAMS) was installed at Tianjin University in October 2017. As an initial testing result, a detection limit of 4.4 × 10−16 for 14C/12C, 3.8 × 10−15 for 10Be/9Be and 6.9 × 10−15 for 26Al/27Al was achieved, respectively.
The system was gradually smoothed and optimized based on a series of standard, blank and real samples measurement.
The detection limit was down to 4.0 × 10−16 for 14C/12C, 2.2 × 10−15 for 10Be/9Be and 5.6 × 10−15 for 26Al/27Al, respectively. More than one thousand samples of 14C, 10Be and 26Al have been successfully measured and analyzed.
The cosmogenic multi-nuclide of 14C, 10Be and 26Al AMS has been available for studies in archaeology, Earth science and environmental science, and some significant jobs still need to be carried out in the near future.
