Cosmogenic in-situ 14C refers to the carbon-14 that is formed by cosmic ray interaction within the crystal lattice of surface materials. In-situ 14C allows researchers to measure processes that have occurred in the era of human civilisations, giving us unprecedented ability to measure rates of change prior to, and since, human impacts. Understanding natural processes at these timescales, and the impacts on them of human activity, has immediate and important applications in diverse NERC science fields such as: hazards and risk, soil production and erosion, agricultural development, archaeology, coastal change, glacial and fluvial processes, and tectonic evolution of mountain ranges. In response to UK community demand we propose to develop a new cutting-edge national laboratory to facilitate in situ 14C dating. Specifically, we will deliver the following scientific capability: Sample preparation for separating quartz for 'in-situ 14C' analyses. A single automated, bespoke extraction line for high-throughput extraction of carbon dioxide from mineral samples. Preparation of accelerator mass spectrometry targets for high-precision, low-concentration analyses. This new capability will allow UK researchers to address critical questions about the future of our planet that previously could not be addressed.

宇宙内14C是指由宇宙射线相互作用在表面材料的晶体晶格中形成的碳-14。原位14C允许研究人员衡量在人类文明时代发生的过程，从而使我们具有前所未有的能力，可以在人类的影响之前衡量变化率。了解这些时间尺度的自然过程，以及对人类活动的影响，在不同的NERC科学领域（例如：危害和风险，土壤产量和侵蚀，农业发展，考古学，沿海变化，冰川和河流过程，以及山脉范围的构造进化）都在不同的NERC科学领域中采取了直接和重要的应用。为了应对英国社区的需求，我们建议开发一个新的尖端国家实验室，以促进原位14C约会。具体而言，我们将提供以下科学能力：将石英分离为“原位14C”分析的样本准备。单个自动化的定制提取线，用于从矿物样品中高通量提取二氧化碳。加速器质谱目标的制备，用于高精度，低浓度分析。这种新的能力将使英国的研究人员能够解决有关我们地球未来的关键问题，这些问题以前无法解决。
