An ultra-sensitive radiocarbon analysis system, proposed here, is central to new, multi-institution research into past fluctuations of Australia's climate, natural resources and ecosystems. Focussed on the 40,000 years of human presence, the research is an integrated approach to changes of earth systems in the Australian region.The equipment is a single-stage accelerator mass spectrometer (SSAMS) with an innovative gas-fed ion source and automated gas-handling system, with simpler processing and smaller samples than present AMS facilities. Future developments include automated multi-sample handling and coupling to microprobe and chromatographic analysers for microscale radiocarbon analysis of complex substances.

这里提出的一种超灵敏的放射性碳分析系统，是对澳大利亚气候、自然资源和生态系统过去波动的新多机构研究的核心。该研究集中于人类存在的4万年，是对澳大利亚地区地球系统变化的综合研究方法。该设备是一个单级加速器质谱仪（SSAMS），具有创新的气供离子源和自动化气体处理系统，处理过程更简单，样品更小。未来的发展包括自动化多样品处理和耦合到微探针和色谱分析仪，用于复杂物质的微尺度放射性碳分析。
