Runaway electrons during a coil quench in stellarators
Pavel Aleynikov, Per Helander, HÃ¥kan M Smith
It is shown that avalanches of runaway electrons can arise in stellarators, even if there is no net toroidal current in the plasma or the magnetic-field coils, if the current in th…

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…
