The NEC Single Stage Accelerator Mass Spectrometer at the Research School of Earth Sciences, Australian National University was installed in January 2007. Over the years many modifications have been performed. For example, a newly designed extractor lens, helium stripping and increased vacuum pumping. This presentation highlights the changes to the NEC SSAMS over the past 14 years highlighting increases in transmission, a discussion of instrumental background, online d13C measurement and sample throughput.
I trained as a marine scientist and geochemist at the University of San Diego and The Australian National University, obtaining a PhD in isotope geochemistry in 2001. I then went to the Center for Accelerator Mass Spectrometry at Lawrence Livermore National Laboratory to learn radiocarbon preparation and measurements using AMS. In 2006 I returned to Australia to take up a research Fellow position as the Head of the newly refurbished Radiocarbon Dating Laboratory at the Research School of Earth Sciences, The Australian National University, where I currently reside.
