Acquisition of a New 3 MV Accelerator Mass Spectrometer

9413337 Donahue 该奖项为亚利桑那大学运行的 2 兆伏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（基于加速器的质谱法）的一部分。该加速器作为多用户设施运行，用于对各种自然样品和人工制品进行 14C 年龄测定。 科学应用范围从全球变化到考古。升级将包括增加高能分析磁体系统、加速器终端绝缘支架、高频脉冲发生器和注入系统静电分析仪。此次升级的具体目的是通过提高加速器的吞吐能力并减少机器停机的机会来减少分析周转时间。 ***

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. ***
