项目摘要

This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2). It will provide funds to upgrade a Fourier Transform Infrared spectrometer (DA3-FTIR). The instrument covers a wide range of light wavelengths and has accessories for high and low temperatures as well as high pressure which makes the instrument useful in addressing an extensive range of problems. Examples of the breadth of supported research are collaborative studies in medicine (bone growth) and ongoing studies in astronomy (identifying dust ejected from old stars). However, the primary focus of the instrument has been on problems important to the geological, planetary and materials science. The upgraded instrument will add to the infrastructure and will help advance fundamental issues while providing opportunities for education and training. The instrument has been used by students at all levels plus students of other faculty at Washington U. and at U. Missouri. The laboratory plans to continue probing the fundamental principles that govern the interaction of heat with matter, and to apply these findings to the Earth and beyond.The existing Fourier Transform Infrared spectrometer (DA3-FTIR) in this laboratory has been used in diverse and numerous research projects since its funding by NSF three decades ago. The DA3-FTIR is a high-end research instrument, with 5 pairs of detectors and beam-splitters that altogether cover the far-IR to the visible. Accessories include a liquid helium cryostat, heaters, and diamond anvil cells to acquire spectra from ~10 to 700 K or at pressure to 50 GPa. Two IR-microscopes are used for very small samples. This instrument is no longer maintained by its manufacturer. The problems are largely electronic. Due to its popularity and robust mechanical components, a small company has filled the market need by offering an upgrade, electronics replacement, and support for this instrument. The upgraded instrument will add to the infrastructure and will help advance fundamental issues in the geological and planetary sciences. Ongoing and planned projects use this instrument and are important to geophysics, volcanology, petrology, and planetary science. Acquiring quantitative spectra vs frequency and T will permit extrapolating to unattainable conditions and will improve understanding of the thermal state and evolution of planets.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项的全部或部分资金根据《2021 年美国救援计划法案》（公法 117-2）提供。它将提供资金升级傅里叶变换红外光谱仪（DA3-FTIR）。该仪器涵盖了广泛的光波长，并具有适用于高温、低温以及高压的附件，这使得该仪器可用于解决广泛的问题。支持研究范围广泛的例子包括医学合作研究（骨骼生长）和正在进行的天文学研究（识别老恒星喷射的尘埃）。然而，该仪器的主要关注点是对地质、行星和材料科学重要的问题。升级后的工具将增加基础设施，有助于解决基本问题，同时提供教育和培训机会。该仪器已被华盛顿大学和密苏里大学各级学生以及其他教师的学生使用。该实验室计划继续探索控制热与物质相互作用的基本原理，并将这些发现应用到地球及其他地区。该实验室现有的傅里叶变换红外光谱仪（DA3-FTIR）已被用于多种领域自三十年前获得国家科学基金会资助以来的研究项目。 DA3-FTIR 是一款高端研究仪器，具有 5 对探测器和分束器，完全覆盖远红外到可见光。配件包括液氦低温恒温器、加热器和金刚石砧座，可获取约 10 至 700 K 或压力至 50 GPa 的光谱。两台红外显微镜用于非常小的样品。该仪器不再由其制造商维护。这些问题主要是电子问题。由于其受欢迎程度和坚固的机械部件，一家小公司通过提供该仪器的升级、电子产品更换和支持来满足市场需求。升级后的仪器将增加基础设施，并将有助于推进地质和行星科学的基本问题。正在进行和计划中的项目使用该仪器，对地球物理学、火山学、岩石学和行星科学很重要。获取定量光谱与频率和 T 的关系将允许推断无法达到的条件，并将提高对行星热状态和演化的理解。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查进行评估，被认为值得支持标准。
