项目摘要

We are an experimental research group specialized in quantum materials. Over the last three decades, we have been using Nuclear Magnetic Resonance (NMR) spectroscopy in cryogenic environment to conduct cutting-edge research on quantum spin liquids and novel superconductors. We have built up our expertise in both the field-swept and frequency-swept modes of NMR data acquisition techniques using superconducting magnets energized by Oxford Instruments IPS-120 Superconducting Magnet Power Supply. However, our vintage IPS-120, purchased in 1994, is approaching the end of its useful life. The intermittent instability of the output current from our IPS-120 has become a major safety hazard for both the students and expensive superconducting magnets. This forced us to indefinitely suspend NMR measurements in the field-swept mode, resulting in months long delays in some of the dissertation research projects of my students. In this proposal, I request emergency funding to purchase a modernized replacement, Mercury-IPS-120 Superconducting Magnet Power Supply, at the total cost of $31,618. The new hardware and software platform of Mercury-IPS-120 are compatible with vintage IPS-120's, and hence we can use Mercury-IPS-120 as the drop-in replacement of IPS-120 with no additional delays. This will ensure seamless continuation of our highly competitive research and safe HQP training.

我们是一个专门研究量子材料的实验研究小组。在过去的三十年里，我们一直在低温环境中使用核磁共振（NMR）光谱进行量子自旋液体和新型超导体的前沿研究。我们已经建立了我们的专业知识，在这两个领域扫描和频率扫描模式的核磁共振数据采集技术使用超导磁体由牛津仪器IPS-120超导磁体电源供电。然而，我们1994年购买的IPS-120葡萄酒已接近使用寿命。IPS-120输出电流的间歇性不稳定性已成为学生和昂贵超导磁体的主要安全隐患。这迫使我们无限期地暂停场扫描模式下的NMR测量，导致我的学生的一些论文研究项目延迟数月。在本提案中，我请求提供紧急资金，以购买一个现代化的替代品，即Mercury-IPS-120超导磁体电源，总费用为31 618美元。Mercury-IPS-120的新硬件和软件平台与老式IPS-120兼容，因此我们可以使用Mercury-IPS-120作为IPS-120的直接替代品，没有额外的延迟。这将确保我们高度竞争的研究和安全的HQP培训的无缝延续。
