Fully-kinetic Ion Simulation of Global Electrostatic Turbulent Transport in C-2U

Understanding the nature of particle and energy transport in field-reversed configuration (FRC) plasmas is a crucial step towards an FRC-based fusion reactor. The C-2U device at Tri Alpha Energy (TAE) achieved macroscopically stable plasmas and electron energy confinement time which scaled favorably with electron temperature$^{\mathrm{[1]}}$. This success led to experimental and theoretical investigation of turbulence in C-2U$^{\mathrm{[2],[3],[4],[5]}}$, including gyrokinetic ion simulations with the Gyrokinetic Toroidal Code (GTC). A primary objective of TAE's new C-2W device is to explore transport scaling in an extended parameter regime. In concert with the C-2W experimental campaign, numerical efforts have also been extended in A New Code (ANC) to use fully-kinetic (FK) ions and a Vlasov-Poisson field solver. Global FK ion simulations are presented. Future code development is also discussed. $^{\mathrm{[1]}}$ M. Binderbauer et al, Phys. Plasmas 22, 056110 (2015). $^{\mathrm{[2]}}$ L. Schmitz et al, Nat.
