Parametric scaling of power exhaust in EU-DEMO alternative divertor simulations
A. E. Järvinen, L. Aho-Mantila, T. Lunt +3
Investigations of parametric scaling of power exhaust in the alternative divertor configuration (ADC) SOLPS-ITER simulation database of the EU-DEMO are conducted and compared to pr…
Runaway dynamics in reactor-scale spherical tokamak disruptions
E. Berger, I. Pusztai, S. L. Newton +4
Understanding generation and mitigation of runaway electrons in disruptions is important for the safe operation of future tokamaks. In this paper we investigate runaway dynamics in…
Bayesian approach for validation of runaway electron simulations
Aaro Järvinen, Tünde Fülöp, Eero Hirvijoki +3
Plasma-terminating disruptions in future fusion reactors may result in conversion of the initial current to a relativistic runaway electron beam. Validated predictive tools are req…
Runaway dynamics in disruptions with current relaxation
István Pusztai, Mathias Hoppe, Oskar Vallhagen
The safe operation of tokamak reactors requires a reliable modeling capability of disruptions, and in particular the spatio-temporal dynamics of associated runaway electron current…
Runaway electron generation during tokamak start-up
M. Hoppe, I. Ekmark, E. Berger +1
Tokamak start-up is characterized by low electron densities and strong electric fields, in order to quickly raise the plasma current and temperature, allowing the plasma to fully i…
Effect of Two-Stage Shattered Pellet Injection on Tokamak Disruptions
O. Vallhagen, I. Pusztai, M. Hoppe +2
An effective disruption mitigation system in a tokamak reactor should limit the exposure of the wall to localized heat losses and to the impact of high current runaway electron bea…
