Paving the way to study the chronology of the early solar system

Radionuclides can serve as tracers and chronometers for environmental processes. The time scale for these clocks is set by the half-life of the respective radioisotope. Using accelerator mass spectrometry and decay counting this project aims investigate the chronology of the Early Solar System.

Single atom counting for stellar nuclear synthesis studies

In this project accelerator mass spectrometry at the 14-million volt accelerator at ANU is used to determine nuclear reaction probabilities relevant for astrophysics.

Strontium-90 in the environment

Strontium is a naturally occurring element that accumulates in bones, with its radioactive isotope Sr-90 posing environmental concerns due its presence in nature.

Total recall – memory effects in negative ion sources

This project investigates contamination effects in negative ion sources used for accelerator mass spectrometry particularly relevant for the measurement of ultra-trace amounts of the long-lived radionuclides Chlorine-36 and Iodine-129 in environmental samples.
