U.S.-Korea Cooperative Research on Anomalous Transport of Magnetically Confined Plasma

该提案要求资金允许德克萨斯大学奥斯汀分校物理学教授Wendell Horton博士与韩国科学技术院（KAIST）物理学教授Choi Duk-In博士进行为期24个月的等离子体动力学基础理论物理方面的合作研究项目。本研究将重点讨论漂移波型的小尺度波动对等离子体磁约束的影响。研究人员将使用解析理论和数值模拟来确定系统中电子和离子粒子传输的性质。电子温度梯度在驱动短波长的磁波动中的作用将被强调。这项研究的直接动机是受控聚变计划中尚未解决的问题，但研究结果将与恒星、磁层和天体物理等离子体中发生的基本过程相关。美国和韩国的合作者是备受尊敬的科学家，他们不仅在提案领域拥有丰富的研究经验和富有成效的发表记录，而且还在过去的合作中发表了20多篇共同发表的论文，其中包括获得NSF资助的合作。int - 8617403。该项目与美韩合作科学项目的目标相关，该项目旨在通过科学信息、思想、技能和技术的交流以及在互利问题上的合作，提高美韩科学家和工程师之间的合作水平。韩国参与该项目得到了韩国科学工程财团（KOSEF）的支持。

This proposal requests funds to permit Dr. Wendell Horton, Professor of Physics, University of Texas at Austin, to pursue with Dr. Duk-In Choi, Professor of Physics, Korea Advanced Institute of Science and Technology (KAIST), for a period of 24 months, a program of cooperative research on the basic theoretical physics aspects of plasma dynamics. This research will deal especially with the effect of small scale fluctuations of the drift wave type on the magnetic confinement of plasmas. The researchers will use analytic theory and numerical simulations to determine the nature of the electron and ion particle transport in the system. The role of the electron temperature gradient in driving short wavelength magnetic fluctuations will be emphasized. The research is directly motivated by unresolved issues in the controlled fusion program, but results of the research will be relevant to basic processes occurring in stellar, magnetospheric, and astrophysical plasmas. The U.S. and Korean collaborators are highly respected scientists who not only have extensive research experience and productive publication records in the field of the proposal but also have produced more than 20 joint publications from past collaboration which includes collaboration under NSF Grant No. INT-8617403. This project is relevant to the objectives of the U.S.-Korea Cooperative Science Program which seeks to increase the level of cooperation between U.S. and Korean scientists and engineers through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit. Korean participation in the project is supported by the Korea Science and Engineering Foundation (KOSEF).
