# Fusion Theory and Computations

The LLNL FESP Fusion Theory and Computations Group has research programs in tokamak core and edge physics (turbulence, transport, equilibrium, stability), tokamak divertor physics, plasma-wall interactions, integrated modeling of experiments, magnetohydrodynamics, laser-plasma interactions, and computational plasma physics. With respect to core tokamak physics, the LLNL FESP remains as a leader in the arena of turbulence code validation and verification. Both the boundary and core physics research efforts have served as the basis for recent success in SciDAC competitions aimed at advancing our understanding of turbulence and in developing approaches for coupling simulations and models so as to make progress in the more ambitious goals of predicting burning plasma performance.

The MFE Theory and Computations Group also conducts theory and simulation of laser-plasma interactions in support of the ignition campaign in NIF, fast ignition, high energy density laboratory plasmas (HEDLP).
