Normal and Transient Plasma/interactions with Material Surfaces-Issues and Supercomputing Challenges

Jeffrey Brooks
Purdue University

Plasma/material interactions are among the most critical issues for fusion power development. Key issues include plasma facing components erosion-limited lifetime, plasma contamination, and tritium inventory. This talk reviews modeling/simulation packages for 1) sputtering erosion/redeposition and related normal-plasma effects, and 2) plasma transient (edge localized modes, disruptions, etc.) response. New proposed work focuses on “Super Packages” for integrated, multiphysics, multi-scale simulations of these issues using coupled codes for plasma edge solutions, erosion/redeposition, transient surface and bulk material response, and self-consistent material response/evolution, and using ~10^5 core petascale supercomputing.
