EAGER: X-ray Diffraction in High Magnetic Fields: A proof of concept diffractometer for the Florida Split Coil 25T Magnet

这个奖项给佛罗里达州立大学是开发一个可行的“概念验证”X射线衍射仪，以利用新的25 T分裂线圈磁铁在国家高磁场实验室（NHMFL）。 X射线衍射和高磁场中的散射技术将用于研究强关联材料中的自旋-晶格耦合、磁致伸缩和轨道有序效应。 这个“概念验证”系统将解决大边缘场对探测器、X射线源和机械部件的影响。待研究的潜在材料将包括多铁性材料、磁电材料和热磁材料、自旋交叉系统和几何阻挫磁系统。“概念验证”X射线衍射仪将是第一台可用于13 T以上稳态磁场的X射线衍射仪。 它将提供一种独特的能力来探测材料中的磁响应，并有望导致新的科学。 新仪器将为下一代衍射系统铺平道路，通过NHMFL向科学界开放增强功能。

This award to Florida State University is to develop a workable 'proof of concept' X-ray diffractometer to take advantage of the new 25T split-coil magnet at the National High Magnetic Field Laboratory (NHMFL). X-ray diffraction and scattering techniques in high magnetic fields will be used to investigate spin-lattice coupling, magnetostriction, and orbital ordering effects in strongly correlated materials. This 'proof of concept' system will address the effects of large fringe fields on detectors, X-ray sources, and mechanical components. Potential materials to be investigated will include, multiferroic, magnetoelectric, and, thermomagnetic materials, spin-cross-over systems, and geometrically frustrated magnetic systems.The 'proof of concept' X-ray diffractometer will be the first available at steady state magnetic fields above 13T. It will provide a unique capability to probe the magnetic responses in materials and is expected to lead to new science. The new instrument will pave the way for a next generation diffraction system with enhanced capabilities open to the scientific community through the NHMFL.
