摘要

We have developed and installed electrostatic deflectors at the injection magnet entrance and exit to enable fast switching between isotopes in AMS measurements. The fast selection of the injected isotope, stable isotope current measurements, and rare isotope detection are all performed with three synchronized real-time NI-PXI computers. With the improvements, we are able to attain a precision of better than 0.2% for the C-14/C-13 ratio of modern samples.
