Abstract Text:
Realta Fusion is developing an integrated set of codes to simulate mirror plasmas. The Wisconsin HTS Axysimmetric Mirror (WHAM) [1] is a simple mirror that aims to validate these models.
Classical mirror confinement results in highly non-Maxwellian plasmas, requiring Fokker-Planck modeling. The axial potential profile must also be self-consistently evolved. The code CQL3D-m [2] models both plasma transport and ambipolar potential in an axisymmetric geometry, while Pleiades [3] accounts for magnetic equilibrium. The ray-tracing code GENRAY-C [4] models EC wave propagation and linear damping. The Monte Carlo particle code FREYA models neutral beam injection. The cylindrical neutral Boltzmann solver KN1DC models the transport of edge neutrals into the plasma. This edge neutral model has been critical in resolving experimental discrepancies in WHAM, where large charge-exchange losses of fast ions result in hybrid classical - gas dynamic confinement. Predictions at improved vacuum conditions will also be discussed.
The coupling between CQL3D-m / GENRAY-C / KN1DC allow for the kinetic, time-dependent modelling of electron-cyclotron heated (ECH) plasma breakdown and buildup. Validation efforts for low-field-side O1 and high-field side X1 launch will be presented.
