Upgrade of the Electron Microprobe Laboratory, University Of Oklahoma

这项NSF拨款将升级和翻新俄克拉荷马州大学（俄克拉荷马州）老化的Cameca SX 50电子探针实验室（EMPL）。我们的仪器安装于1988年;这是北美第三台这样的机器。该仪器前两次进行了部分升级，但硬件故障更加频繁，关键部件老化，因此需要对仪器进行全面翻新，以确保实验室的持续运作。这些升级将提高仪器的可靠性以及成像和X射线信号的质量。该设施为NSF和其他联邦机构赞助的研究人员、麻省理工学院和其他地区大学和学院的本科生和研究生以及包括个人和大公司在内的私营部门提供服务。EMPL通过以极具竞争力的成本向私营部门提供高质量的分析服务，为国家的经济发展做出了贡献。自1989年成立以来，仪器使用平均约为200小时/月，停机时间最短。EMPL得到了研究副总裁办公室（OVPR）的年度基本预算的大力支持，OVPR已承诺提供额外资金，以确保此次升级奋进的成功。

This NSF grant will upgrade and renovate an aging Cameca SX50 Electron Microprobe Laboratory (EMPL) at the University of Oklahoma (OU). Our instrument was installed in 1988; it was the third such machine in North America. The instrument has been partially upgraded on two previous occasions, but more frequent hardware malfunctions and aging of key components dictate the need for a complete renovation of the instrument to ensure the continued operation of the laboratory. These upgrades will improve the reliability of the instrument and the quality of imaging and x-ray signals. The facility serves researchers sponsored by NSF and other Federal agencies, undergraduate and graduate students at OU and other regional universities and colleges, and the private sector including individuals and large companies. The EMPL contributes to the economic development of the state by making high-quality analytical services available to the private sector at very competitive cost. Instrument usage has averaged approximately 200 hrs/month since inception in 1989 with minimal down time. The EMPL is well supported by an annual base budget from the Office of the Vice President of Research (OVPR) at OU, and the OVPR has committed additional funds to ensure the success of this upgrade endeavor.
