Reduction of electrostatic turbulence in a quasi-helically symmetric stellarator via critical gradient optimization
G. T. Roberg-Clark, P. Xanthopoulos, G. G. Plunk
We present a stellarator configuration optimized for a large threshold (``critical gradient'') for the onset of the ion temperature gradient (ITG) driven mode, which achieves the l…
Scattering of energetic electrons by heat-flux-driven whistlers in flares
G. T. Roberg-Clark, O. V. Agapitov, J. F. Drake +1
The scattering of electrons by heat-flux-driven whistler waves is explored with a particle-in-cell (PIC) simulation relevant to the transport of energetic electrons in flares. The…
Wave generation and heat flux suppression in astrophysical plasma systems
G. T. Roberg-Clark, J. F. Drake, M. Swisdak +1
Heat flux suppression in collisionless plasmas for a large range of plasma is explored using two-dimensional particle-in-cell simulations with a strong, sustained thermal gradi…
Suppression of electron thermal conduction by whistler turbulence in a sustained thermal gradient
G. T. Roberg-Clark, J. F. Drake, C. S. Reynolds +1
The dynamics of weakly magnetized collisionless plasmas in the presence of an imposed temperature gradient along an ambient magnetic field is explored with particle-in-cell simulat…
