9413337 Donahue This award provides partial funding for the upgrade of a 2-megavolt tandem particle accelerator operated at the University of Arizona as part of the NSF-Arizona AMS Facility (Accelerator-based Mass Spectrometry). The accelerator is operated as a multi-user facility for 14C age dating of a wide variety of natural samples and artifacts. Science applications range from global change to archeological. The upgrade will consist of the addition of a high-energy analyzing magnet system, accelerator terminal insulating supports, a high frequency pulser, and an injection system electrostatic analyzer. The upgrade is aimed specifically at decreasing the turn-around time for analyses by increasing the throughput capabilities of the accelerator and decreasing the chances of machine down-time. ***

该合同为亚利桑那大学运行的2兆伏特串联粒子加速器的升级提供部分资金，该加速器是NSF-Arizona AMS设施（加速器质谱）的一部分。加速器作为一个多用户设施运行，用于各种自然样品和人工制品的14C年龄测定。科学应用范围从全球变化到考古学。升级将包括增加一个高能分析磁铁系统、加速器终端绝缘支撑、一个高频脉冲发生器和一个注入系统静电分析仪。升级的目的是通过提高加速器的吞吐能力和减少机器停机的机会来减少分析的周转时间。＊＊＊
