Emergency Replacement of Vintage Superconducting Magnet Power Supply

点击翻译按钮获取中文摘要

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.
