Long lasting plasma density structures utilizing tailored density profiles
Mufei Luo, Caterina Riconda, Anna Grassi +4
Using fully kinetic Particle In Cell simulations, we investigate the stability and performance of autoresonant plasma beat wave excitation in plasmas with tailored density profiles…
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…
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…
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…
