Evaluation of the Dreicer runaway generation rate in the presence of high-Z impurities using a neural network
L Hesslow, L Unnerfelt, O Vallhagen +4
Integrated modelling of electron runaway requires computationally expensive kinetic models that are self-consistently coupled to the evolution of the background plasma parameters.…

Effect of plasma elongation on current dynamics during tokamak disruptions
T. Fülöp, P. Helander, O. Vallhagen +6
Plasma terminating disruptions in tokamaks may result in relativistic runaway electron beams with potentially serious consequences for future devices with large plasma currents. In…

Influence of massive material injection on avalanche runaway generation during tokamak disruptions
L Hesslow, O Embréus, O Vallhagen +1
In high-current tokamak devices such as ITER, a runaway avalanche can cause a large amplification of a seed electron population. We show that disruption mitigation by impurity inje…
