The pellet rocket effect in magnetic confinement fusion plasmas
Nico J. Guth, Oskar Vallhagen, Per Helander +3
Pellets of frozen material travelling into a magnetically confined fusion plasma are accelerated by the so-called pellet rocket effect. The non-uniform plasma heats the pellet abla…
Reduced modeling of scrape-off losses of runaway electrons during tokamak disruptions
Oskar Vallhagen, Lise Hanebring, Tünde Fülöp +2
Accurate modeling of runaway electron generation and losses during tokamak disruptions is crucial for the development of reactor-scale tokamak devices. In this paper we present a r…
Evolution of the autoresonant plasma wave excitation in two-dimensional particle-in-cell simulations
Mufei. Luo, Caterina. Riconda, Anna. Grassi +4
The generation of an autoresonantly phase-locked high amplitude plasma waves to the chirped beat frequency of two driving lasers is studied in two dimensions using particle-in-cell…
Fluid and kinetic studies of tokamak disruptions using Bayesian optimization
Ida Ekmark, Mathias Hoppe, Tünde Fülöp +4
When simulating runaway electron dynamics in tokamak disruptions, fluid models with lower numerical cost are often preferred to more accurate kinetic models. The aim of this work i…
