An Experimental Plasma Dynamo Program for Investigations of Fundamental Processes in Heliophysics
Benjamin Brown, Cary Forest, Mark Nornberg +3
Plasma experiments in laboratory settings offer unique opportunities to address fundamental aspects of the solar dynamo and magnetism in the solar atmosphere. We argue here that gr…
Self-consistent kinetic simulations of lower hybrid drift instability resulting in electron current driven by fusion products in tokamak plasmas
J W S Cook, S C Chapman, R O Dendy
We present particle-in-cell (PIC) simulations of minority energetic protons in deuterium plasmas, which demonstrate a collective instability responsible for emission near the lower…
Electron current drive by fusion-product-excited lower hybrid drift instability
J. W. S. Cook, S. C. Chapman, R. O. Dendy
We present first principles simulations of the direct collisionless coupling of the free energy of fusion-born ions into electron current in a magnetically confined fusion plasma.…
Momentum injection in tokamak plasmas and transitions to reduced transport
F. I. Parra, M. Barnes, E. G. Highcock +2
The effect of momentum injection on the temperature gradient in tokamak plasmas is studied. A plausible scenario for transitions to reduced transport regimes is proposed. The trans…
Transport Bifurcation in a Rotating Tokamak Plasma
E. G. Highcock, M. Barnes, A. A. Schekochihin +3
The effect of flow shear on turbulent transport in tokamaks is studied numerically in the experimentally relevant limit of zero magnetic shear. It is found that the plasma is linea…
Turbulent transport in tokamak plasmas with rotational shear
M. Barnes, F. I. Parra, E. G. Highcock +3
Nonlinear gyrokinetic simulations have been conducted to investigate turbulent transport in tokamak plasmas with rotational shear. At sufficiently large flow shears, linear instabi…
