内容简介：

The aim of the lecture is to provide a comprehensive introduction of boundary plasma physics, plasma-material interactions (PMI), and computational PMI modelling with an emphasis on fusion plasmas. The critical challenge for fusion development nowadays is how to keep the tokamak core hot and meanwhile the plasma facing components ‘cold’, separating by an extremely narrow boundary plasma region. This lecture will address rising interest in these areas and will in part introduce the breadth and depth of the subject including edge plasma physics, the scrape-off layer physics, plasma-surface interactions in fusion edge plasmas, and modeling of the plasma edge and materials.

报告人简介：

Xueqiao Xu (徐学桥）is a theoretical and computational plasma physicist with general interests in plasma physics, and scientific computing. Specific plasma physics experience: particle simulations, continuum simulations, gyro-fluid simulations, fluid simulations, linear and nonlinear theory of micro-instabilities, turbulence, transport, and boundary plasma physics. Specific achievements include: (1) Developed the BOUT two-fluid edge turbulence code and developed the BOUT++ code jointly with University of York; (2) Lead physics developer for 5D continuum edge gyrokinetic code TEMPEST; (3) Co-invented new Monte Carlo scheme for usual gyro-kinetic df particle-in-cell plasma micro-turbulence simulations for modeling Coulomb collisions; (4) leads an international collaboration for ongoing development of the BOUT++ code on ELMs and edge turbulence modelling with collaborative groups from US, UK, China, R. Korea, and Japan. He is a co-author of 2014 Nuclear Fusion Prize paper with Phil Snyder.
