Theory and Computational Sciences

The mission of the Theory group at General Atomics is: 

  • to perform fundamental theoretical research in the theory of fusion plasmas

  • to provide theoretical support to the DIII-D National Fusion Facility
  • to facilitate scientific discovery in fusion research through the application of advanced computer science techniques.

The General Atomics Theory and Simulation of Fusion Plasmas Program (GA Theory Group) supports the Department of Energy, Office of Fusion Energy Sciences' (OFES) overarching goals of advancing fundamental understanding of plasma science, advancing understanding and innovation in high-performance fusion plasmas, including burning plasmas, and resolving outstanding scientific issues and establishing reduced-cost paths to more attractive fusion energy systems.

The GA Theory Group and DIII-D National Fusion Facility staff work closely in identifying and addressing key physics issues relevant to the OFES goals. Analytic theories are developed to model physical effects, and numerical codes are implemented to treat realistic geometries and to integrate interrelated complex phenomena. Code verification and validation are performed against experimental data in order to reliably predict the performance of fusion systems.
