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 08-589. The award provides funds to support undergraduate participation in the overall research effort, which is being funded separately by the DoE [OFES Science report #09ER55049]. The project is devoted to analytic and numerical study of nonlinear interaction and turbulence of Alfven waves in the Large Plasma Device (LAPD) which is a part of the Basic Plasma Science Facility (BAPSF) at UCLA. The proposed research is aimed at extending the results obtained for incompressible magnetohydrodynamic turbulence to plasma turbulence, and at providing analytic and numerical support to the experiments on Alfvenic turbulence conducted in LAPD. The research will be strongly integrated with teaching. It is proposed to develop the new course onMHD Turbulence on the graduate level, and the new course on Plasma Astrophysics for graduate and advanced undergraduate students. The courses will reflect the interdisciplinary nature of the proposed research, and will cater to students in Physics, Astronomy and Engineering Departments. An essential part of the project is effective integration of state-of-the art analytic and numerical methods with laboratory studies, which is indispensable in training graduate and undergraduate student. This NSF award provides travel support for the Graduate Research Assistant involved with this research project.

该奖项是为了响应向 NSF/DoE 基础等离子体科学与工程合作伙伴联合征集 NSF 08-589 提交并审查的提案而颁发的。该奖项提供资金支持本科生参与整体研究工作，该研究工作由美国能源部单独资助 [OFES 科学报告#09ER55049]。该项目致力于对大型等离子体装置 (LAPD) 中阿尔芬波的非线性相互作用和湍流进行分析和数值研究，该装置是加州大学洛杉矶分校基础等离子体科学设施 (BAPSF) 的一部分。拟议的研究旨在将不可压缩磁流体动力湍流所获得的结果扩展到等离子体湍流，并为在洛杉矶警察局进行的阿尔芬湍流实验提供分析和数值支持。 研究将与教学紧密结合。 建议为研究生开设MHD湍流新课程，为研究生和高年级本科生开设等离子体天体物理学新课程。这些课程将反映拟议研究的跨学科性质，并将迎合物理、天文学和工程系的学生。该项目的一个重要部分是将最先进的分析和数值方法与实验室研究有效结合，这对于培养研究生和本科生来说是不可或缺的。该 NSF 奖项为参与该研究项目的研究生研究助理提供差旅支持。
