THE ANU AMS SYSTEM AND RESEARCH-PROGRAM

Since the previous conference, the Australian National University AMS system has undergone a series of refinements, and the research program conducted on the facility has expanded significantly. The system is n ow used for the measurement of the isotopes Be-10, C-14, Al-26, Cl-36, Ni-59, and I-129. The research program includes projects in hydrology , geomorphology, environmental geochemistry and biomedicine. Chlorine- 36 remains the principal isotope, but the demand for other heavy isoto pes, especially Al-26, has burgeoned during 1992-93. This paper descri bes the recent advances with AMS measurements on the 14UD, and details the current status and future direction of the AMS research program.
