Dynamics of cold pulses induced by super-sonic molecular beam injection in the EAST tokamak
Yong Liu, Yuejiang Shi, Tao Zhang +9
Evolution of electron temperature, electron density and its fluctuation with high spatial and temporal resolutions are presented for the cold pulse propagation induced by super-son…
Electron acceleration in a JET disruption simulation
Cristian Sommariva, Eric Nardon, Peter Beyer +2
Runaways are suprathermal electrons having sufficiently high energy to be continuously accelerated up to tens of MeV by a driving electric field [1]. Highly energetic runaway elect…
Kinetic Theory of Transport Driven Current in Centrally fuelled Plasmas
J. M. Rax, J. Robiche, R. Gueroult +1
When a steady-state cylindrical plasma discharge is centrally fuelled, the collisionless radial electron flux is canonically coupled to an axial current. The identification and ana…
Non-Maxwellian fast particle effects in gyrokinetic GENE simulations
A. Di Siena, T. Görler, H. Doerk +6
Fast ions have recently been found to significantly impact and partially suppress plasma turbulence both in experimental and numerical studies in a number of scenarios. Understandi…
Collisional relaxation and dynamical scaling in multiparticle collisions dynamics
Stefano Lepri, Hugo Bufferand, Guido Ciraolo +3
We present the Multi-Particle-Collision (MPC) dynamics approach to simulate properties of low-dimensional systems. In particular, we illustrate the method for a simple model: a one…
Fluid and kinetic modelling for non-local heat transport in magnetic fusion devices
Guido Ciraolo, Hugo Bufferand, Pierfrancesco Di Cintio +7
In order to improve the presently used ad hoc flux limiter treatment of parallel heat flux transport in edge plasma fluid codes we consider here a generalized version of the Fourie…
