Attosecond dispersion as a diagnostics tool for solid-density laser-generated plasmas

Andréas Sundström, István Pusztai, Per Eng-Johnsson +1

Extreme-ultraviolet pulses can propagate through ionised solid-density targets, unlike optical pulses and, thus, have the potential to probe the interior of such plasmas on sub-fem…

The hot-tail runaway seed landscape during the thermal quench in tokamaks

Ida Svenningsson, Ola Embreus, Mathias Hoppe +2

Runaway electron populations seeded from the hot-tail generated by the rapid cooling in plasma-terminating disruptions are a serious concern for next-step tokamak devices such as I…

DREAM: a fluid-kinetic framework for tokamak disruption runaway electron simulations

M. Hoppe, O. Embreus, T. Fülöp

Avoidance of the harmful effects of runaway electrons (REs) in plasma-terminating disruptions is pivotal in the design of safety systems for magnetic fusion devices. Here, we descr…

Modelling of runaway electron dynamics during argon-induced disruptions in ASDEX Upgrade and JET

K. Insulander Björk, O. Vallhagen, G. Papp +7

Disruptions in tokamak plasmas may lead to the generation of runaway electrons that have the potential to damage plasma-facing components. Improved understanding of the runaway gen…

Effects of magnetic perturbations and radiation on the runaway avalanche

P. Svensson, O. Embreus, S. L. Newton +3

The electron runaway phenomenon in plasmas depends sensitively on the momentum-space dynamics. However, efficient simulation of the global evolution of systems involving runaway el…

Multimillijoule terahertz radiation from laser interactions with microplasma-waveguides

Ke Hu, Longqing Yi, Tünde Fülöp

When a relativistic, femtosecond laser pulse enters a waveguide, the pulse energy is coupled into waveguide optical modes. The longitudinal laser field effectively accelerates elec…
