This award supports Professor Eric Hellstrom and a junior colleague and graduate student of the University of Wisconsin to collaborate in materials research with Dr. P Majewski and his group at the Institute for Non-Metallic Inorganic Materials of the University of Stuttgart. The objective of their research is to increase the flux pinning in bismuth-based high temperature superconductors. Their approach will be to create flux pinning centers in silver sheathed bismuth-based tape by manipulating the chemistry of the bismuth-based superconductor and varying the thermal processing. The collaboration brings together the expertise of the U.S. group in the scientific issues involved in fabricating, processing and characterizing long lengths of silver-sheathed high temperature superconductors, with the detailed knowledge of phase relations in the bismuth-based system generated at the University of Stuttgart. Increased flux pinning will raise the current density that these superconductors can carry at thirty degrees Kelvin to a level that will greatly expand the applications in which they can be used. The complementary expertise of the U.S. and German groups creates a uniquely qualified collaboration to pursue this valuable objective.

该奖项支持Eric Hellstrom教授，威斯康星大学的初级同事和研究生，与P Majewski博士及其小组合作，在斯图加特大学的非金属无机材料研究所与他的小组合作。 他们研究的目的是增加基于二晶型的高温超导体中的通量固定。 他们的方法是通过操纵基于二抗性的超导体的化学反应并改变热处理，在银色护套的基于bismuth的胶带中创建通量固定中心。 该合作将美国小组的专业知识汇集在制造，加工和表征长长的银色高温高温超导体的科学问题中，以及在斯图加特大学产生的基于二晶鼠系统的相关系统中的详细知识。 增加的通量固定将提高这些超导体可以以三十度开尔文携带的当前密度，从而大大扩展使用它们的应用。 美国和德国团体的互补专业知识创建了一个独特的合格合作，以追求这一宝贵的目标。
