Acquisition compact helium re liquefier

项目摘要

This proposal seeks financial support for the acquisition of equipment to re-liquefy helium boil-off from cryogenic equipment. The reliquefier will be used continuously year-round in McMaster Low-Temperature High-Field Laboratory (Mac LTHF Lab). I founded Mac LTHF Lab in 2002 in the Brockhouse Institute for Materials Research based on funding from NSERC, CFI (Canadian Foundation for Innovation), OIT (Ontario Innovation Trust), and McMaster, with the total budget exceeding $1,000,000. It has a wide variety of cryogenic equipment for NMR, transport, ac susceptibility, and high-pressure measurements. Mac LTHF Lab is by far the biggest user of liquid helium in McMaster. Currently, our helium liquefier in the Brockhouse Institute is unable to supply sufficient amount of liquid helium when Mac LTHF Lab is operating at the full capacity. Our recent acquisition of a top-loading dilution refrigerator and a 16 Tesla superconducting magnet will exacerbate the helium shortage in McMaster. In order to gain the maximum scientific dividend from the large financial investment into Mac LTHF Lab, we need to ensure that affordable and sufficient liquid helium is available on time. The proposed acquisition will not only resolve the helium shortage issue, but also yield significant savings of the operational cost of Mac LTHF Lab. The total savings of our operational cost in the coming 5 years will exceed the modest cost of the acquisition ($50,080) of the re-liquefier.

该提案寻求财政支持，以获取设备以从低温设备中重新煮沸。 Reliquefier将全年使用McMaster低温高场实验室（MAC LTHF实验室）使用。我根据NSERC，CFI（加拿大创新基金会），OIT（安大略省创新信托基金）和麦克马斯特（McMaster）和麦克马斯特（McMaster）的资助，于2002年在Brockhouse材料研究所创立了Mac LTHF实验室，总预算超过100万美元。它具有多种用于NMR，运输，AC敏感性和高压测量值的低温设备。 Mac LTHF实验室是迄今为止麦克马斯特液态氦气的最大用户。目前，当Mac LTHF实验室全部运行时，我们在Brockhouse Institute的氦气液体无法提供足够的液态氦气。我们最近收购了上装载稀释冰箱和16特斯拉超导磁铁，这将加剧麦克马斯特的氦短缺。为了从大型金融投资到Mac LTHF实验室获得最大的科学股息，我们需要确保可以按时提供负担得起的足够的液态氦气。拟议的收购不仅将解决氦短缺问题，还可以节省Mac LTHF实验室的运营成本。未来5年内我们的运营成本的总节省将超过Re-Liquefier收购（$ 50,080）的适度成本。
