Abstract Text:
TAE Technologies, Inc, has an active fusion plasma research program centered around the FRC (Field Reversed Configuration) magnetic topology and the existing C-2W (aka Norman) experiment. The main goals of our current FRC research program are 1) to study confinement of energy at high electron temperatures in the C-2W experiment, and 2) to master plasma control methods needed to increase plasma temperatures to commercializable fusion conditions in a future device.
Two particle-in-cell HPC (High Performance Computing) codes are under development to support the main goals of TAE’s research program: 1) the ANC kinetic micro-stability code to understand energy confinement in FRC plasmas, and 2) the FPIC kinetic macro-stability code to model global stability of FRC plasmas and to study plasma control methods that could be deployed on C-2W and future devices. Recent physics and model advances for these two codes include: 1) increased physics understanding of the difference between experimentally measured and computationally simulated turbulence; 2) electron model improvement and benchmarking for the ANC turbulence code; 3) development of theoretical stability models suggested by the results of FPIC global stability simulations, and 4) benchmark of the FPIC code against normal modes. Numerical algorithm improvements include the 5) coupled core-edge turbulence simulation, 6) continuity methods, and (7) ADIOS2 implementation in ANC; and 8) the particle/boundary interaction method of FPIC.
These two simulation codes are the most computationally demanding components of the Integrated Modeling project at TAE, dubbed the FRC Whole Device Model (WDM). The WDM is a hierarchy of models which will use a global transport model as the framework to integrate microstability, macrostability, electron dynamics, neutral transport, and neutral beam and RF source terms to perform full system simulations.
