SOFT: A synthetic synchrotron diagnostic for runaway electrons
Mathias Hoppe, Ola Embréus, R. Alexander Tinguely +3
Improved understanding of the dynamics of runaway electrons can be obtained by measurement and interpretation of their synchrotron radiation emission. Models for synchrotron radiat…
Collisionless Reconnection in Magnetohydrodynamic and Kinetic Turbulence
N. F. Loureiro, S. Boldyrev
It has recently been proposed (Loureiro & Boldyrev 2017; Mallet et al. 2017) that the inertial interval in magnetohydrodynamic (MHD) turbulence is terminated at small scales not by…
A positive-definite form of bounce-averaged quasilinear velocity diffusion for the parallel inhomogeneity in a tokamak
Jungpyo Lee, David Smithe, John Wright +1
In this paper, the analytical form of the quasilinear diffusion coefficients is modified from the Kennel-Engelmann diffusion coefficients to guarantee the positive definiteness of…
Magnetohydrodynamic turbulence mediated by reconnection
Stanislav Boldyrev, Nuno F. Loureiro
Magnetic field fluctuations in MHD turbulence can be viewed as current sheets that are progressively more anisotropic at smaller scales. As suggested by Loureiro & Boldyrev (2017)…
Fully kinetic versus reduced-kinetic modelling of collisionless plasma turbulence
D. Groselj, S. S. Cerri, A. Banon Navarro +5
We report the results of a direct comparison between different kinetic models of collisionless plasma turbulence in two spatial dimensions. The models considered include a first pr…
Experimental observations and modelling of intrinsic rotation reversals in tokamaks
Y. Camenen, C. Angioni, A. Bortolon +8
The progress made in understanding spontaneous toroidal rotation reversals in tokamaks is reviewed and current ideas to solve this ten-year-old puzzle are explored. The paper inclu…
