项目摘要

The proposed electron microprobe is an instrument for the chemical analysis of sampleswith high spatial resolution and detection limits down to the 10 ppm range. It is requestedas replacement for an old and somewhat outdated instrument, which was acquired in2001. The latter instrument was already the replacement for a previous machine thatwas in operation since 1989.The electron microprobe will be located at Bayerisches Geoinstitut (BGI), a researchcenter at Bayreuth University. BGI is generally considered to be one of the world´sleading institutions in high-pressure research in Earth sciences. The mission of theinstitute is to study the structure and dynamics of the Earth and of planets by experimentsin the laboratory. Current areas of active research include the formation and earlyevolution of the Earth and of the terrestrial planets, the mass transport processes insubduction zones, rheology and dynamics of the Earth´s mantle, the composition ofEarth´s core, the formation of critical metal deposits, and experimental volcanology. Theanalysis of the chemical composition of samples by electron microprobe is central tomost research projects and the instrument is usually in automatic operation 24 hours perday. Since 2020, an additional research group in geochemistry and cosmochemistry hasbeen established at BGI, which complements the experimental research by chemicalanalyses of terrestrial and extra-terrestrial samples. Moreover, the electron microprobefacility, as the only instrument of this kind in Bayreuth, provides analytical services forthe entire university, including in particular for the departments of chemistry,environmental sciences, and materials science.

所提出的电子微探针是对具有高空间分辨率的样品进行化学分析的仪器，检测限至10 ppm范围。要求替代一种旧的和一些过时的仪器，该乐器是在2001年收购的。后一种仪器已经是自1989年以来运行的先前机器的替代品。电子微型探针将位于Bayreuth University的研究中心Bayerisches Geoinstitut（BGI）。 BGI通常被认为是地球科学高压研究中世界上倡导的机构之一。该研究所的任务是通过实验室中研究地球和行星的结构和动态。当前积极研究的领域包括地球和地球行星的形成和早期演变，质量运输过程不服从区域，地球披风的流变学和动力学，地球核心的组成，关键金属沉积物的形成以及实验火山学。通过电子微探针对样品的化学组成的分析是大多数研究项目的核心，并且该仪器通常每天24小时自动操作。自2020年以来，在BGI建立了一个地球化学和宇宙化学研究小组，该小组符合了陆地和横向样品的化学杂志的实验研究。此外，作为Bayreuth的唯一这种工具，电子微型预科性为整个大学提供了分析服务，包括化学，环境科学和材料科学部门。
