With support from the Chemical Measurement and Imaging Program in the Division of Chemistry (CHE), the Established Program to Stimulate Competitive Research (EPSCoR), and the Molecular Biophysics Program in the Division of Molecular and Cellular Biosciences (MCB), Professor Richard Kurtz and his multidisciplinary team at Louisiana State University are developing the capability to recover and reuse the boil-off gas from liquid helium, a non-renewable resource. Liquid helium enables a broad range of low temperature technologies and is crucial to superconducting instrumentation. It is essential that the community move to conserve and recycle helium from the boil-off of these instruments so that new discoveries to improve the intellectual and physical wellbeing of society can continue. This project will allow recovery of helium from the LSU Chemistry Department’s Nuclear Magnetic Resonance (NMR) facility as well as the Center for Advanced Microstructures and Devices (CAMD) synchrotron light source. The boil-off helium gas from these facilities will be collected, compressed, and transported to the LSU’s existing Physics Department Helium Recovery and Liquefaction Center to be re-liquefied and returned for re-use. The superconducting magnets in the LSU NMR facility and the two superconducting insertion devices at the LSU CAMD synchrotron collectively consume a significant volume of liquid helium per year, all of which is currently lost to boil-off. This helium recovery project involves the installation of equipment at each site consisting of gas collection bags, compressors, and recovery gas manifolds to capture this helium boil-off for reliquefaction and re-use. The high rate of recovery expected will be monitored and reported back to NSF. This project will significantly improve our stewardship of this limited resource and the anticipated savings will support multiple NSF-funded programs impacted by the cost and availability of liquid helium.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.

在化学测量和成像计划中的支持（CHE）的支持下，刺激竞争研究的既定计划（EPSCOR）以及分子和细胞生物科学和细胞生物科学分部（MCB）的分子生物物理学计划（MCB），Richard Kurtz教授及其在Louisiana State University的多学科团队中的多学科团队正在恢复不良的能力。液体氦气可实现广泛的低温技术，对于超导仪器至关重要。社区至关重要的是要节省和回收这些工具的沸腾，以便可以继续进行新的发现以改善社会的智力和身体健康。该项目将允许从LSU化学系的核磁共振（NMR）设施以及晚期微观结构和设备中心（CAMD）同步器光源回收氦气。这些设施的沸腾的氦气将被收集，压缩并运送到LSU现有的物理部门氦气回收中心和液化中心，并重新融资并返回以重复使用。 LSU NMR设施中的超导磁铁以及LSU CAMD同步器的两个超导插入设备共同消耗了大量的液态氦气，目前所有这些都丢失了。这个氦恢复项目涉及在每个站点安装设备，包括收集袋，压缩机和恢复气歧管，以捕获此氦气boil，以进行ReliqueFaction和Re-Rese。预期的高回收率将受到监控，并将其报告回NSF。该项目将大大改善我们对这项有限资源的管理，预期的节省将支持多个受NSF资助的计划，这些计划受液体氦气的成本和可用性影响。该奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的影响审查标准来评估通过评估来诚实地支持。
