This award is made in response to a proposal submitted to and reviewed under the NSF/DOE Partnership in Basic Plasma Science and Engineering joint solicitation NSF 09-596. The award provides funds to support undergraduate participation in the overall research effort, which is being funded separately by the DOE under contract to University of Wisconsin (Grant DE-FG02-05ER54831).This project would continue supporting magnetohydrodynamic (MHD) experiments addressing questions on the selfgeneration of magnetic fields (dynamos) from flows of liquid sodium and expand this line of research into studies of plasma dynamos. The experimental approach of this research complements more traditional analytical and computational approaches to understanding how magnetic fields can be generated in planets and stars.Two experiments are part of this proposal: a liquid sodium experiment expected to be dynamo from theory, that is operational and making scientific discoveries, and a plasma based experiment under construction (with support from the NSF Major Research Instrumentation program) that will be operational in approximately three years. The goal of both experiments is to experimentally investigate fundamental processes related to self-generation of magnetic fields in naturally occurring dynamos. Both begin as unmagnetized, flowing conducting fluid with large magnetic Reynolds numbers (the key dimensionless number characterizing magnetic field evolution).A central part of the dynamo research includes the training and mentoring of undergraduate and graduate students. Students are involved in all aspects of the project and are regularly sent to scientific meetings where they present their results and are exposed to the larger scientific community. Outreach activities include public lectures, press releases coordinated by the UW Media Relations and websites.The NSF support of undergraduate participation adds a broader educational impact through the early-year training of students by introducing them to scientific research as a possible career path.

该裁决是针对基本等离子科学与工程联合招标NSF 09-596的NSF/DOE合作伙伴关系提交和审查的提案。 The award provides funds to support undergraduate participation in the overall research effort, which is being funded separately by the DOE under contract to University of Wisconsin (Grant DE-FG02-05ER54831).This project would continue supporting magnetohydrodynamic (MHD) experiments addressing questions on the selfgeneration of magnetic fields (dynamos) from flows of liquid sodium and expand this line of research into studies of plasma发电机。这项研究的实验方法补充了更传统的分析和计算方法，以了解如何在行星和星星中产生磁场。这是该建议的一部分：这是该提案的一部分：一种液体钠实验，预计将是从理论上发电的，这是运营的，并且是基于科学的发现，以及基于等离子体的实验，以及在NSF研究中的支持，该计划是由NSF大型研究工具的支持。两个实验的目的是实验研究与自然发生的发电机中磁场自生成相关的基本过程。两者都以磁性磁力较大的数字（表征磁场演化的关键无量纲数字）的流动流动开始。发电机研究的中心部分包​​括对本科生和研究生的培训和指导。学生参与该项目的各个方面，并定期将其送到科学会议，在那里他们呈现结果，并接触到更大的科学界。外展活动包括公开讲座，由大学媒体关系和网站协调的新闻发布。NSF对本科参与的支持通过将学生介绍给科学研究作为可能的职业道路，从而通过对学生的早期培训来增加更广泛的教育影响。
