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…
