The impact of fusion-born alpha particles on runaway electron dynamics in ITER disruptions
Andrej Lier, Gergely Papp, Philipp Lauber +3
In the event of a tokamak disruption in a D-T plasma, fusion-born alpha particles take several milliseconds longer to thermalise than the background. As the damping rates drop dras…
Modeling the complete prevention of disruption-generated runaway electron beam formation with a passive 3D coil in SPARC
RA Tinguely, VA Izzo, DT Garnier +8
The potential formation of multi-mega-ampere beams of relativistic "runaway" electrons (REs) during sudden terminations of tokamak plasmas poses a significant challenge to the toka…
Edge Momentum Transport by Neutrals: an Interpretive Numerical Framework
J. T. Omotani, S. L. Newton, I. Pusztai +3
Due to their high cross-field mobility, neutrals can contribute to momentum transport even at the low relative densities found inside the separatrix and they can generate intrinsic…
Neoclassical flows in deuterium-helium plasma density pedestals
Stefan Buller, Istvan Pusztai, Sarah Newton +1
In tokamak transport barriers, the radial scale of profile variations can be comparable to a typical ion orbit width, which makes the coupling of the distribution function across f…
Radio frequency induced and neoclassical asymmetries and their effects on turbulent impurity transport in a tokamak
István Pusztai, Matt Landreman, Albert Mollén +2
Poloidal asymmetries in the impurity density can be generated by radio frequency heating in the core and by neoclassical effects in the edge of tokamak plasmas. In a pedestal case…
Possible mechanism responsible for observed impurity outward flow under radio frequency heating
S. Moradi, T. Fülöp, A. Mollén +1
The effect of poloidal asymmetry of impurities on impurity transport driven by electrostatic turbulence in tokamak plasmas is analyzed. It is found that in the presence of in-out a…
