Comprehensive evaluation of the linear stability of Alfvén eigenmodes driven by alpha particles in an ITER baseline scenario
A. C. A. Figueiredo, P. Rodrigues, D. Borba +8
The linear stability of Alfvén eigenmodes in the presence of fusion-born alpha particles is thoroughly assessed for two variants of an ITER baseline scenario, which differ signific…
The generation of magnetic fields by the Biermann battery and the interplay with the Weibel instability
K. M. Schoeffler, N. F. Loureiro, R. A. Fonseca +1
An investigation of magnetic fields generated in an expanding bubble of plasma with misaligned temperature and density gradients (driving the Biermann battery mechanism) is perform…
Viriato: a Fourier-Hermite spectral code for strongly magnetised fluid-kinetic plasma dynamics
N. F. Loureiro, W. Dorland, L. Fazendeiro +4
We report on the algorithms and numerical methods used in Viriato, a novel fluid-kinetic code that solves two distinct sets of equations: (i) the Kinetic Reduced Electron Heating M…
Kinetic microtearing modes and reconnecting modes in strongly magnetised slab plasmas
A Zocco, N F Loureiro, D Dickinson +2
The problem of the linear microtearing mode in a slab magnetised plasma, and its connection to kinetic reconnecting modes, is addressed. Electrons are described using a novel hybri…
A systematic approach to the linear-stability assessment of Alfvén eigenmodes in the presence of fusion-born alpha particles for ITER-like equilibria
P. Rodrigues, A. Figueiredo, J. Ferreira +6
A systematic approach to assess the linear stability of Alfvén eigenmodes in the presence of fusion-born alpha particles is described. Because experimental results for ITER are not…
Fluctuation-dissipation relations for a plasma-kinetic Langevin equation
A. Kanekar, A. A. Schekochihin, W. Dorland +1
A linearised kinetic equation describing electrostatic perturbations of a Maxwellian equilibrium in a weakly collisional plasma forced by a random source is considered. The problem…
Intrinsic momentum transport in up-down asymmetric tokamaks
Justin Ball, Felix I. Parra, Michael Barnes +4
Recent work demonstrated that breaking the up-down symmetry of tokamak flux surfaces removes a constraint that limits intrinsic momentum transport, and hence toroidal rotation, to…
Electromagnetic effects in the stabilization of turbulence by sheared flow
M. D. J. Cole, S. L. Newton, S. C. Cowley +4
We have extended our study of the competition between the drive and stabilization of plasma microinstabilities by sheared flow to include electromagnetic effects at low plasma …
Gyrokinetic simulations of the tearing instability
R. Numata, W. Dorland, G. G. Howes +3
Linear gyrokinetic simulations covering the collisional -- collisionless transitional regime of the tearing instability are performed. It is shown that the growth rate scaling with…
