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 envisioned and initiated a program of first-principles simulations of energetic particle turbulence and transport by deploying two complementary, global, nonlinear gyrokinetic turbulence codes: particle-in-cell GTC and continuum GYRO.
