Controlling Fusion Plasmas: Energetic Particle Turbulence Gyrokinetic Simulation of Energetic Particle Turbulence & Transport (GSEP) Assessing the effects of energetic particles on the performance of the burning plasmas in ITER Zhihong Lin (project webpage) University of California, Irvine

The goal of the DOE SciDAC Center for Gyrokinetic Simulation of Energetic Particle Turbulence and Transport (GSEP) is to develop predictive capability for assessing the effects of energetic particles on the performance of the burning plasmas in ITER. To achieve this ambitious goal, the GSEP Center has initiated a program of first-principles simulations of energetic particle turbulence and transport by deploying two complementary, global, nonlinear gyrokinetic codes: particle-in-cell GTC and continuum GYRO. The GSEP project focuses on further development of gyrokinetic turbulence codes for energetic particle simulations, comprehensive energetic particle physics studies, extensive verifications through cross-code benchmarks and theory-simulation comparisons, and vigorous validations using data from existing tokamaks including DIII-D experiments dedicated for energetic particle physics.
