Self-consistent modelling and qualitative comparison of mildly relativistic runaway electron dynamics with a closed flux surface formation model during tokamak startup
Y. Lee, H. -T. Kim, P. C. de Vries +14
A model for mildly relativistic Runaway Electrons (REs) is developed in a reduced-kinetic form and qualitatively compared with radiation characteristics observed in KSTAR ohmic sta…

The role of nonlinear absorption of an ECR beam for fusion plasma pre-ionization
Tulchhi Ram, T. Wauters, P. C. de Vries +2
This study investigates the nonlinear interactions between electrons and electron-cyclotron resonance (ECR) heating beams in magnetized, low-temperature fusion plasmas, focusing on…

Inelastic collisions facilitating runaway electron generation in weakly-ionized plasmas
Y. Lee, P. Aleynikov, P. C. de Vries +7
Dreicer generation is one of the main mechanisms of runaway electrons generation, in particular during tokamak startup. In fully ionized plasma it is described as a diffusive flow…
