This award provides equipment funds and summer support for two undergraduate students from Saint Mary's University of Minnesota for ten weeks in each of the summers of 2010-2012, to be engaged (a) in testing a new approach to magnetic shielding for large (eight-inch) diameter photomultiplier tubes (PMTs) in the MicroBooNE (Fermilab E974) detector, a liquid argon time projection chamber (LArTPC) that will run in the Booster Neutrino Beam (BNB) line at Fermilab; and (b) in parameterizing shielded tube performance characteristics (timing, gain, angular response, etc.) prior to installation and in situ in the detector. The broader impact includes providing an extraordinary and well-focused physics research experience for undergraduate students to work as part of an ongoing experiment at a major national laboratory as well as enabling Professor Nienaber to work with the undergraduate students to prepare neutrino physics outreach talks that the students can deliver to members of the Saint Mary's University and wider Winona, MN communities. It is anticipated that this project would have direct impact on the strength of the undergraduate research component of Saint Mary's Physics Department's major programs, and would indirectly improve participating students' ability to contribute to department offerings in modern physics, quantum mechanics, and upper-division laboratory courses.

该奖项为明尼苏达圣玛丽大学的两名本科生提供设备资金和暑期支助，他们将在2010-2012年夏季每年十周从事：(A)测试MicroBooNE(Fermilab E974)探测器中大直径(8英寸)光电倍增管(PMT)的磁屏蔽新方法；(B)测试将在Fermilab的助推中微子束(BNB)生产线上运行的液体Ar时间投影室(LArTPC)；以及(B)对屏蔽管的性能特性(定时、增益、角响应等)进行参数化。在安装之前并在检测器中就地安装。更广泛的影响包括为本科生提供非凡和专注的物理研究体验，作为正在进行的国家主要实验室实验的一部分，以及使Nienaber教授能够与本科生合作准备中微子物理拓展讲座，学生可以向圣玛丽大学和更广泛的明尼苏达州威诺纳社区的成员进行演讲。预计该项目将对圣玛丽大学物理系主修课程的本科生研究部分的实力产生直接影响，并间接提高参与项目的学生为现代物理、量子力学和高级实验室课程的系级课程做出贡献的能力。
