Comparison of local and global gyrokinetic calculations of collisionless zonal flow damping in quasi-symmetric stellarators
J. Smoniewski, E. Sánchez, I. Calvo +2
The linear collisionless damping of zonal flows is calculated for quasi-symmetric stellarator equilibria in flux-tube, flux-surface, and full-volume geometry. Equilibria are studie…
Plasma Confinement Mode Classification Using a Sequence-to-Sequence Neural Network With Attention
Francisco Matos, Vlado Menkovski, Alessandro Pau +2
In a typical fusion experiment, the plasma can have several possible confinement modes. At the TCV tokamak, aside from the Low (L) and High (H) confinement modes, an additional mod…
The JOREK non-linear extended MHD code and applications to large-scale instabilities and their control in magnetically confined fusion plasmas
M Hoelzl, GTA Huijsmans, SJP Pamela +50
JOREK is a massively parallel fully implicit non-linear extended MHD code for realistic tokamak X-point plasmas. It has become a widely used versatile code for studying large-scale…
Tomographic reconstruction of the runaway distribution function in TCV using multispectral synchrotron images
T. A. Wijkamp, A. Perek, J. Decker +8
Synchrotron radiation observed in a quiescent TCV runaway discharge is studied using filtered camera images targeting three distinct wavelength intervals. Through the tomographic S…
The impact of magnetic fields on momentum transport and saturation of shear-flow instability by stable modes
A. E. Fraser, P. W. Terry, E. G. Zweibel +2
The Kelvin-Helmholtz (KH) instability of a shear layer with an initially-uniform magnetic field in the direction of flow is studied in the framework of 2D incompressible magnetohyd…
Topology of the Warm plasma dispersion relation at the second Harmonic Electron Cyclotron Resonance Layer
Pim L. Joostens, Egbert Westerhof
The Warm Plasma Dispersion Relation, for waves in the electron cyclotron resonance range of frequencies, can be cast into the form of a bi-quadratic equation for , where t…
Simulation of positive streamers in CO and in air: the role of photoionization or other electron sources
Behnaz Bagheri, Jannis Teunissen, Ute Ebert
Positive streamer discharges have been studied and modelled extensively in air. Here we study positive streamers in CO with and without oxygen admixtures; they are relevant for…
Exploring zonal flow mediated saturation on stellarators
C. D. Mora Moreno, J. H. E. Proll, G. G. Plunk +1
In stellarators, zonal flow activity depends sensitively on geometry of the three dimensional magnetic field, via an interplay of mechanisms that is not fully understood. In this w…
Transition from no-ELM response to pellet ELM triggering during pedestal build-up -- insights from extended MHD simulations
S Futatani, A Cathey, M Hoelzl +6
Pellet ELM triggering is a well established scheme for decreasing the time between two successive ELM crashes below its natural value. Reliable ELM pacing has been demonstrated exp…
Radiation asymmetry and MHD destabilization during the thermal quench after impurity Shattered Pellet Injection
D. Hu, E. Nardon, M. Hoelzl +7
The radiation response and the MHD destabilization during the thermal quench after a mixed species Shattered Pellet Injection (SPI) with impurity species neon and argon are investi…
Non-linear extended MHD simulations of type-I edge localised mode cycles in ASDEX Upgrade and their underlying triggering mechanism
Andres Cathey, M. Hoelzl, K. Lackner +9
A triggering mechanism responsible for the explosive onset of edge localised modes (ELMs) in fusion plasmas is identified by performing, for the first time, non-linear magnetohydro…
The physics of streamer discharge phenomena
Sander Nijdam, Jannis Teunissen, Ute Ebert
In this review we describe a transient type of gas discharge which is commonly called a streamer discharge, as well as a few related phenomena in pulsed discharges. Streamers are p…
Understanding the reduction of the edge safety factor during hot VDEs and fast edge cooling events
F. J. Artola, K. Lackner, G. T. A. Huijsmans +3
In the present work a simple analytical approach is presented in order to clarify the physics behind the edge current density behaviour of a hot plasma entering in contact with a r…
Addendum to `Mapping electron dynamics in highly transient EUV photon-induced plasmas: a novel diagnostic approach using multi-mode microwave cavity resonance spectroscopy'
Bart Platier, Ferdi van de Wetering, Mark van Ninhuijs +4
A new approach for an in-line beam monitor for ionizing radiation was introduced in a recent publication (Beckers, J., et al. "Mapping electron dynamics in highly transient EUV pho…
Runaway electron synchrotron radiation in a vertically translated plasma
M. Hoppe, G. Papp, T. Wikjamp +6
Synchrotron radiation observed from runaway electrons (REs) in tokamaks depends upon the position and size of the RE beam, the RE energy and pitch distributions, as well as the loc…
Flux-driven integrated modelling of main ion pressure and trace tungsten transport in ASDEX Upgrade
O. Linder, J. Citrin, G. M. D. Hogeweij +9
Neoclassical and turbulent heavy impurity transport in tokamak core plasmas are determined by main ion temperature, density and toroidal rotation profiles. Thus, in order to unders…
