Strong gradient neoclassical transport in the plateau regime
Silvia Trinczek, Felix I. Parra, Peter J. Catto +1
Strong gradient regions in tokamaks such as the pedestal or internal transport barriers are regions of reduced turbulence where neoclassical transport can play a dominant role. In…
Collisional passing alpha energy transport in nearly quasisymmetric stellarators
Miguel Calvo-Carrera, Peter J. Catto
Recent advances in stellarator optimization have found nearly precise quasisymmetric configurations. These are expected to reduce the non-turbulent background plasma transport to a…
Strong gradient effects on neoclassical electron transport and the bootstrap current
Silvia Trinczek, Felix I. Parra, Peter J. Catto
Standard approaches to neoclassical theory do not extend into regions of strong gradients in tokamaks such as the pedestal and internal transport barriers. Here, we calculate the m…
Quasilinear drift kinetic theory of alpha particle transport by neoclassical tearing modes
Elizabeth A. Tolman, Peter J. Catto
Kinetic theory of particles near resonances is a current topic of discussion in plasma physics and astrophysics. We extend this discussion to the kinetic theory of the interaction…
