This project is designed to contribute significantly to providing interesting laboratory and research opportunities for undergraduate students in the area of solid state physics and to providing students with the opportunity to share in the excitement of the recent developments in high temperature superconductivity. The major acquisition will be a closed cycle helium gas cryosystem capable of controlling temperature within the 10K - 330K range. Used in conjunction with a current source and nanovoltmeter, this system will provide for solid state laboratory experiments and undergraduate research in the fields of superconductivity and transport properties such as resistivity and Hall effect. The university will match the award with an equal amount of funds.

该项目旨在为固体物理领域的本科生提供有趣的实验室和研究机会，并为学生提供分享高温超导最新发展的机会，做出重大贡献。 此次收购的主要项目是一个闭式循环氦气低温系统，能够将温度控制在 10K - 330K 范围内。 该系统与电流源和纳伏表结合使用，将为超导和电阻率和霍尔效应等输运特性领域的固态实验室实验和本科生研究提供支持。 大学将为该奖项提供同等数额的资金。
