The ARL-SEMQ electron microprobe in the Department of Marine, Earth, and Atmospheric Sciences (MEAS) at North Carolina State University is critical for acquiring compositional data from geologic material, mainly minerals, within an academic program that serves graduate student and faculty research, and provides information for graduate theses, journal publications, and the general public. The computer that was interfaced with the microprobe in year 2004 has recently failed, and the microprobe has not been professionally serviced since year 2000. While the instrument is still operating, including the rebuilt computer, the instrument overall is failing in areas of electron beam stability, high vacuum, counting electronics, and in some hardware components - and the repaired computer can no longer be trusted. This proposal requests funds for a new instrument-interfaced computer and a one-time visit by a professional service person to bring the electron microprobe up to optimum operating condition.

北卡罗莱纳州立大学海洋、地球和大气科学系（MEAS）的ARL-SEMQ电子显微探针对于从地质材料（主要是矿物）中获取成分数据至关重要，该电子显微探针在一个学术项目中为研究生和教师研究服务，并为研究生论文、期刊出版物和公众提供信息。2004年与微探头连接的计算机最近发生了故障，自2000年以来，微探头就没有进行过专业维修。虽然仪器仍在运行，包括重建的计算机，但仪器总体上在电子束稳定性、高真空、计数电子和一些硬件组件方面出现故障，修复后的计算机不再可信。该提案要求为一台新的仪器接口计算机和专业服务人员的一次访问提供资金，以使电子显微探针达到最佳操作状态。
