Size and Surface Effects in 3He and Other Materials at Low Temperatures

所提出的研究涉及从毫克开尔文到微开尔文范围内材料的性质的研究。他们建议继续研究3He中的激发如何与表面相互作用，特别是将研究3He-硅界面的相互作用。他们还计划将他们关于抑制~3He超流转变的测量扩展到更小的孔隙尺寸，并使用不同的池设计，使他们能够同时测试对转变温度的抑制以及对孔隙中超流体部分的抑制。最后，提出了与新的微开尔文和顶部加载设备相关的实验，包括研究饱和混合物中的邻近效应引起的超流性，以及尺寸和表面散射对材料内耗的影响。

The research proposed is concerned with the study of the properties of materials in the millikelvin to microkelvin regimes. They propose to continue the study of how excitations in 3He interact with surfaces, and in particular will study the interaction of the 3He-Silicon interface. They also plan to extend their measurements on the suppression of the superfluid transiton of 3He to smaller pore sizes and with a different cell design which will permit them to assay both the suppression of the transition temperature as well as the suppression of the superfluid fraction in the pores. Finally, experiments associated with the new microkelvin and top loading facilities are proposed which include the study of proximity effect induced superfluidity in a saturated mixture as well as size and surface scattering effects on internal friction in materials.
