Neoclassical transport in strong gradient regions of large aspect ratio tokamaks
Autor: Silvia Trinczek, Felix I. Parra, Peter J. Catto, Iván Calvo, Matt Landreman
Publikováno v: Journal of Plasma Physics. 89
We present a new neoclassical transport model for large aspect ratio tokamaks where the gradient scale lengths are of the size of the poloidal gyroradius. Previous work on neoclassical transport across transport barriers assumed large density and pot

Merging of the superbanana plateau and transport regimes in nearly quasisymmetric stellarators
Autor: Peter J. Catto, Elizabeth A. Tolman, Felix I. Parra
Publikováno v: Journal of Plasma Physics. 89
Alpha particle confinement is one of the most demanding issues for stellarators. It now seems clear that it is possible to design optimized stellarators that confine the background plasma at near tokamak radial transport levels. Moreover, adequate co

Lower hybrid current drive in a tokamak for correlated passes through resonance
Autor: Peter J. Catto
Publikováno v: Journal of Plasma Physics. 87
Standard quasilinear descriptions are based on the constant magnetic field form of the quasilinear operator so improperly treat the trapped electron modifications associated with tokamak geometry. Moreover, successive poloidal transits of the Landau

Reimagining full wave rf quasilinear theory in a tokamak
Autor: Peter J. Catto, E.A. Tolman
Publikováno v: Journal of Plasma Physics. 87
The velocity dependent resonant interaction of particles with applied radiofrequency (rf) waves during heating and current drive in the presence of pitch angle scattering collisions gives rise to narrow collisional velocity space boundary layers that

Collisional effects on resonant particles in quasilinear theory
Autor: Peter J. Catto
Publikováno v: Journal of Plasma Physics. 86
A careful examination of the effects of collisions on resonant wave–particle interactions leads to an alternate interpretation and deeper understanding of the quasilinear operator originally formulated by Kennel & Engelmann (Phys. Fluids, vol. 9, 1

Drift kinetic theory of alpha transport by tokamak perturbations
Autor: Peter J. Catto, E.A. Tolman
Upcoming tokamak experiments fueled with deuterium and tritium are expected to have large alpha particle populations. Such experiments motivate new attention to the theory of alpha particle confinement and transport. A key topic is the interaction of

Practical gyrokinetics
Autor: Peter J. Catto
Publikováno v: Journal of Plasma Physics. 85
Thousands of gyrokinetic papers have been published since the introduction of the gyrokinetic change of variables. The intent here is not to review the field, but rather the goal is to present a tutorial providing insight into why gyrokinetics is an
