Partnership Center for High-Fidelity Boundary Plasma Simulation

simpler approaches in which the plasma is characterized only by average properties have not fared well. This challenge is exacerbated by the boundary region's complex geometry.

The XGC suite of advanced high fidelity kinetic simulation codes, run on extreme-scale computers, is designed to address the physics challenges arising in this boundary region. XGC uses first-principles based equations to maximize physics fidelity, with the degree of fidelity increasing as the capabilities of leadership class computers continue to grow. This project is essential to understanding existing tokamak experiments and to predicting with greater confidence the operation and performance of the ITER international fusion reactor, under construction in France, and of future fusion reactors. To address these challenges, we have assembled a team of world experts in physics, computer science, applied mathematics, and data management to collaboratively keep XGC at the cutting edge of computational and algorithmic development, as well as of physics fidelity.
