Conventional low-energy AMS has seen major progress in measurement efficiency via optimized beam stripping in the accelerator but also in measurement selectivity via improved suppression of molecular and atomic isobars after the accelerator. This led to a separation of systems specialized either on measurements of radiocarbon or on determination of a broader spectrum of radionuclides ranging...
The Xi'an AMS Center is equipped with a 3 MV accelerator mass spectrometer for multi-nuclides measurements, which provides a background of 10Be/9Be ratio up to 1.56×10-16, giving us favorable conditions to carry out environmental tracing study by using Chinese loess 10Be. Chinese loess-paleosol sequences are considered as one of three pillars for the global change research, along with marine...
Interferences from isobars typically restrict the applicability of AMS to selected long-lived radionuclides. The novel Ion-Laser InterAction Mass Spectrometry (ILIAMS) technique at the Vienna Environmental Research Accelerator (VERA) can overcome this limitation in many cases by highly-efficient isobar removal at eV-energies in a gas-filled radiofrequency quadrupole. The virtually complete...
Constraining the sources, transport, and burial of OC in marine sediments is of fundamental importance for understanding the carbon cycle on a range of spatial and temporal scales. Marginal seas receive substantial terrestrial inputs from rivers and comprise hotspots for both organic carbon (OC) burial and remineralization. However, much remains unknown about factors that control the sources,...
Modern AMS instruments are still following design concepts of the pioneering experimental setups as invented during the early times of AMS. However, measurement procedures have undergone a continuous evolution. Groundbreaking progress was made when molecular isobaric interferences could be eliminated by collisional interaction of swift ions with the stripper gas atoms. Radiocarbon detection,...
