A new-generation gas-source radiocarbon system for integrated environmental and archaeological research

这里提出的一种超灵敏的放射性碳分析系统，是澳大利亚气候、自然资源和生态系统过去波动的多机构新研究的核心。这项研究聚焦于人类存在的4万年，是对澳大利亚地区地球系统变化的综合方法。该设备是一种单级加速器质谱仪(SAMS)，具有创新的气体馈送离子源和自动气体处理系统，与现有的AMS设施相比，处理更简单，样品更少。未来的发展包括自动多样品处理以及与用于复杂物质的微尺度放射性碳分析的微探针和色谱分析仪的耦合。

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.
