RUI: Testing and Characterization of Cryogenic Magnetic Shielding for Photomultiplier Tubes at Liquid Argon Temperatures, and Preparation for Photomultiplier Tube Deployment in the

该奖励为来自明尼苏达大学圣玛丽大学的两名本科生提供设备资金和夏季支持，在2010-2012年的每个夏季提供10周的时间，用于(a)测试MicroBooNE （Fermilab E974）探测器中大直径（8英寸）光电倍增管（PMTs）的磁屏蔽新方法，该探测器是一个液态氩时间投影室（LArTPC），将在费米实验室的助推器中微子束（BNB）线中运行；(b)在探测器安装前和原位参数化屏蔽管的性能特性（定时、增益、角响应等）。更广泛的影响包括为本科生提供一个非凡的和重点突出的物理研究经验，作为一个主要的国家实验室正在进行的实验的一部分，以及使尼纳伯教授与本科生一起准备中微子物理外展会谈，学生可以提供给圣玛丽大学的成员和更广泛的威诺纳，MN社区。预计该项目将对圣玛丽物理系主要项目的本科生研究部分的实力产生直接影响，并将间接提高参与学生在现代物理，量子力学和高级实验课程方面的能力。

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.
