Equipment Upgrade for the Cameca SX-50 Electron Microprobe at the University of Oregon

小行星9510026 俄勒冈州大学地质科学系将升级他们现有的Cameca SX-50电子探针显微分析仪（EPMA）。该仪器构成了他们分析设施的核心，对他们近一半部门目前正在进行的研究至关重要。 升级将包括购买一个SUN SPARCstation 5，作为通过Cameca提供的“SXPACK”升级的一部分，图像处理软件和两个用于精确分析轻元素的X射线衍射假晶体。 SUN计算机将取代一台DEC PDP-11小型计算机，这台小型计算机的使用寿命即将结束，更重要的是，在软件开发方面不再得到支持。 如果没有这种升级，PI的科学创造力和生产力将受到过时的计算机系统的严重限制。 此外，基于太阳能的计算机系统将提供一个现代化的计算平台，与其网络上的现有机器完全兼容，并将能够访问最近开发的软件包，这些软件包旨在充分利用SX-50的能力。 赝晶体技术和分析技术的最新进展使分析从硼到氧范围内的元素的能力达到了通常与较重元素相关的精确度和准确度。正在进行和计划中的研究项目需要对各种散装成分中的氧和硼进行相对精确的分析。 ***

9510026 Rice The Department of Geological Sciences at the University of Oregon will upgrade their present Cameca SX-50 electron probe microanalyzer (EPMA). This instrument forms the core of their analytical facilities and is crucial for research currently being conducted by nearly half of their department. The upgrade will include the purchase of a SUN SPARCstation 5 as part as part of a "SXPACK" upgrade offered though Cameca, image processing software and two x-ray diffracting pseudocrystals used for the precise analysis of light elements. The SUN computer will replace a DEC PDP-11 minicomputer that is at the end of its useful life, and more importantly is no longer supported in terms of software development. Without this upgrade, the PI's scientific creativity and productivity would be severely limited by an antiquated computer system. Additionallly, the SUN-based computer system will provide a modern computing platform that is fully compatible with existing machines on their network and will enable access to recently developed software packages designed to fully utilize the capabilities of the SX-50. Recent advances in pseudocrystal technology and analytical techniques have resulted in the capability of analyzing elements in the range from boron to oxygen with precision and accuracy approaching that commonly associated with heavier elements. Ongoing and planned research projects require relatively precise analyses of oxygen and boron in a variety of bulk compositions. ***
