Collision operator for electron runaway in cold weakly-ionized plasmas
Yeongsun Lee, Pavel Aleynikov, Peter de Vries +2
In cold weakly-ionized plasmas, Dreicer generation mechanism can be non-diffusive as demonstrated in [Y. Lee et. al. Phys. Rev. Lett. 133 17 175102 (2024)]. By expanding the previo…

Investigation of resonant layer response in electron viscosity regime
Yeongsun Lee, Jace Waybright, Jong-Kyu Park
We present a supplementary study of previous work in Waybright and Park [Phys. Plasmas 31, 022502 (2024)] which demonstrates a substantial effect of electron viscosity on the reson…

Quantification of locked mode instability triggered by a change in confinement
M. Peterka, J. Seidl, T. Markovic +24
This work presents the first analysis of the disruptive locked mode (LM) triggered by the dynamics of a confinement change. It shows that, under certain conditions, the LM threshol…
