The AMS system

The AMS system of the Leibniz-Laboratory

The Leibniz-Labor accelerator mass spectrometry (AMS) system is a 3 Million Volt Tandetron 4130 AMS system from High Voltage Engineering designed for the analysis of 14C.

The AMS system is equipped with a single cesium sputter ion source. The basic layout of the system is shown in the schematic below.

The distinguishing feature of our AMS system is the simultaneous acceleration and measurement of all three carbon isotopes (12C,13C, 14C), made possible by a separator-recombinator magnet system, shown in the photograph, with mechanical attenuation of the 12C beam intensity („chopper“).
