Simulation Center for Runaway Electron Avoidance and Mitigation

and (3) investigate the viability and effectiveness of the leading candidate schemes for runaway mitigation. In all three areas, members of the team have carried out scoping studies that establish the readiness for rapid and critical advances, especially in the deployment and further development of large-to extreme-scale simulation tools. Our multi-pronged computational approach will include (1) relativistic Fokker-Planck solutions in discretized phase space, (2) self-consistent particle-in-cell techniques, (3) particle-based Monte-Carlo solutions, and (4) MHD-particle hybrid simulations. Cross-check between these different methods will provide an additional means for verification and will further bolster the fidelity of our physics prediction. Validation against experimental results will bring confidence to the predictive capability for ITER and likely lead to new ideas for understanding and mitigating the thermal quench driven runaway electron phenomenon.
