项目摘要

This award supports Professor Mark W. Meisel of the Microkelvin Research Laboratory at the University of Florida to collaborate in low temperature physics and cryogenic engineering research with Professor Georgio Frossati and others of the Ultralow Temperature Group at the Kamerlingh Onnes Laboratorium of the University of Leiden, Netherlands. The proposed research in physics will focus on several difficult problems associated with the study of phase boundaries and polarization in superfluid Helium-3 and highly polarized forms of normal liquid and superfluid helium-3. Their efforts in cryogenic engineering will address the problems of achieving ultralow temperature in continuous and pulsed ultra-high magnetic fields and on the design of heat exchangers which are tuned to cool pure Helium-3/Helium-4 mixtures to heretofore unattainable low temperatures. The field of experimental ultralow temperature physics, by its nature, requires careful attention and innovative thought in both physics and cryogenic engineering. The proposed international collaboration links two leading ultra-low temperature research groups which are interested in pursuing both the science and the technology necessary to attack fundamental problems in this field. Together, they will be in an even stronger position to design new approaches to questions that require novel techniques to advance the state-of-the-art.

该奖项支持佛罗里达大学微开尔文研究实验室的 Mark W. Meisel 教授与莱顿大学 Kamerlingh Onnes 实验室超低温小组的 Georgio Frossati 教授和其他人在低温物理和低温工程研究方面进行合作，荷兰。拟议的物理学研究将集中于与超流 Helium-3 中的相边界和极化以及正常液体和超流 Helium-3 的高度极化形式研究相关的几个难题。他们在低温工程方面的努力将解决在连续和脉冲超高磁场中实现超低温的问题，以及设计热交换器的问题，这些热交换器可将纯氦 3/氦 4 混合物冷却到迄今为止无法达到的低温。实验超低温物理领域，就其本质而言，需要物理学和低温工程方面的认真关注和创新思维。拟议的国际合作将两个领先的超低温研究小组联系起来，他们有兴趣追求解决该领域基本问题所需的科学和技术。他们将共同处于更有利的位置，设计新方法来解决需要新技术来推进最先进技术的问题。
