Plasma Surface Interactions: Predicting the Performance and Impact of Dynamic PFC Surfaces

This project seeks to develop and integrate high-performance simulation tools for predicting plasma facing component (PFC) operating lifetime and the impact of the evolving surface morphology and composition of tungsten-based PFCs on plasma contamination.

This project will enable discovery of phenomena controlling critical PFC performance issues and will quantitatively predict their impact on both steady-state and transient plasma conditions.

The outcome of this project will be a suite of coupled plasma and materials modeling tools and a leadership- class PFC simulator to predict PFC evolution and feedback to the boundary plasma.
