SGER: Superleak Superfluid Helium Free-Jets: Development and Use

探索研究特别补助金（SGER）奖提供资金支持超慢、超冷“超级泄漏”超流氦束的科学应用的建设、测试和开发。 除了超流体本身固有的新颖的相干性之外，超级泄漏氦束还提供了似乎前所未有的方向性和强度。 虽然超级泄漏源仍然处于发展阶段，但它似乎越来越有可能提供非凡的和全新的方法来研究超流氦以及表征和合成材料，特别是在纳米尺度上。

This Special Grant for Exploratory Research (SGER) award provides funds to support the construction, testing, and development for scientific use of an ultra-slow, ultra-cold "superleak" superfluid helium beam. The superleak helium beam offers seemingly unprecedented directionality and intensity in addition to the novel coherence properties intrinsic to the superfluid itself. Although the superleak source is still very much in a developmental stage, it seems increasingly likely to offer extraordinary and completely novel ways of investigating superfluid helium and of characterizing and synthesizing materials, particularly on nanoscale dimensions.
