Consequently, AMS dating is invaluable to a wide range of disciplines including archaeology, art history, and environmental and biological sciences.and graphitisation lines in 2010 has enabled us to quadruple our throughput and reduce our turnaround time for AMS (now averaging 6 weeks), while maintaining our quality control, improving our background limits and reducing sample size requirements.

The final velocity is a few percent of the speed of light or about 50 million miles per hour.

The analyzing and switching magnets select the mass of the radionuclide of interest, further reducing the intensity of neighboring stable isotopes.

In addition, they eliminate molecules completely by selecting only the highly charged ions that are produced in the terminal stripper.

(Highly charged molecules are unstable since they are missing the electrons that bind the atoms together).

These are repelled from the positive terminal, accelerating again to ground potential at the far end.

The name tandem accelerator comes from this dual acceleration concept.

At this point the beam is about 10 microamps which corresponds to 10 ions per second (mostly the stable isotopes).

The injector magnet bends the negative ion beam by 90 to select the mass of interest, a radioisotope of the element inserted in the sample holder, and reject the much-more-intense neighboring stable isotopes.

Isotope ratios are measured by alternately selecting the stable and radioisotopes with the injector and analyzing magnets.
