This award will fund upgrades to the existing in situ 14C extraction and CO2 purification systems at the University of Arizona with automated electromechanical valve actuators and associated control systems, and will install automated liquid N2 delivery systems. In addition, thermal control equipment for the in situ 14C graphitization systems will be upgraded to provide more reliable temperature control and to facilitate future improvements to our graphitization procedures. Because we are retrofitting our existing vacuum systems, implementing these technologies will require only minimal re-characterization of the systems' behavior. In all, we project that the proposed upgrades will enable an increase of our annual laboratory sample throughput by up to a factor of four - without additional extraction systems and with half of the current personnel. The new automation systems will significantly broaden the impact of in situ 14C on process-oriented geomorphic and Quaternary geologic research. It will also simplify and shorten the process of training additional personnel, which will allow greater interaction with and involvement of graduate students and outside researchers, and will expand opportunities for collaboration both within and outside the University of Arizona.

该奖项将资助亚利桑那大学现有的原位14C提取和二氧化碳纯化系统，并使用自动机电阀执行器和关联的控制系统进行升级，并将安装自动液体N2输送系统。此外，将升级原位14C石墨化系统的热控制设备，以提供更可靠的温度控制，并促进我们的石墨化程序的未来改进。因为我们正在改造现有的真空系统，所以实施这些技术只需要对系统行为的最小重新特征。总的来说，我们预测拟议的升级将使我们的年度实验室样本吞吐量增加多达四倍 - 没有其他提取系统，并且有一半的当前人员。新的自动化系统将显着扩大原位14C对以过程为导向的地质和第四纪地质研究的影响。它还将简化和缩短培训其他人员的过程，这将允许与研究生和外部研究人员的更多互动和参与，并将扩大亚利桑那大学内外协作的机会。
