Dr Andrew Smith

Principal Research Scientist

Role at ANSTO

Andrew is a Physicist with 23 years' experience in Accelerator Mass Spectrometry [AMS] and 37 years' experience with particle accelerator systems. Andrew commenced work at ANSTO in October 1989 on two projects: the joint Australian National University [ANU]/ANSTO 36CI AMS measurement program and the development of a tandem accelerator facility for AMS at ANSTO. This facility is now known as ANTARES: the Australian National Tandem for Applied Research. Andrew's principal contributions to ANTARES were in the development of the high-intensity, multi-sample negative ion source,the isotope cycling system ('bouncer') and with the ion beam optic modelling of beam line and accelerator compontents.

Between 1996 and 1999 Andrew was leader of the project 'Long-lived radionuclides in Antarctic ice as tracers and chronometers in global climate change studies'. This project involved collaboration between ANSTO, CSIRO, Australian Antarctic Division [AAD] and the National Institute for Water and Atmosphere [NIWA], Wellington, NZ. This collaboration was continued under the 'Historical atmospheric radiomethane' project. In 1997/98 Andrew participated in an expedition to Law Dome, Antarctica, collecting firn air samples for measurement of the 14C of air back to ~ 1942 AD.

Restructuring at ANSTO towards the end of 2002 saw Andrew leading the task 'Radiocarbon signatures of greenhouse gases' in the 'Cosmogenic Archives of the Southern Hemisphere' [CcASH] project, within the Institute for Environmental Research [IER]. In 2005/06 Andrew lead an expedition to Law Dome, retrieving a large diameter, thermally-drilled 'ANSTO' ice core to a depth of 260m (ice age ~ 1615 AD), principally for global climate change studies.

Andrew continues to work on applications of long-lived radionuclides (14C & 10Be) in polar ice sheets as tracers and chronometers and on further development of AMS at ANSTO, particularly in the continuing development of ANSTO's capability to measure 14C in ultra-small carbon samples containing just a few micrograms of carbon and in the measurement of the short-lived radioisotope 7Be. Samples for 7Be studies are taken annually at Law Dome, most recently in the 2011/12 reason. Currently Andrew is leading the task "Ice sheets & microcarbon' in the research area 'Isotopic Proxies of Palaeoclimate' which in turn is included within the "Isotopes for Climate Change and Atmospheric Systems' project.
