Kinetic modelling of runaway electron generation in argon-induced disruptions in ASDEX Upgrade
K. Insulander Björk, G. Papp, O. Embreus +8
Massive material injection has been proposed as a way to mitigate the formation of a beam of relativistic runaway electrons that may result from a disruption in tokamak plasmas. In…
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.…
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…
Effect of partially-screened nuclei on fast-electron dynamics
Linnea Hesslow, Ola Embréus, Adam Stahl +4
We analyze the dynamics of fast electrons in plasmas containing partially ionized impurity atoms, where the screening effect of bound electrons must be included. We derive analytic…
