Description
The role of a runaway current in a post disruption plasma is investigated through numerical simulations in the single helicity limit. Linear results are verified against analytical theory and benchmarked against results already present in the literature. In particular, the presence of a microlayer below the resistive one is confirmed and the effect of the electron inertia on it is also investigated. Nonlinear results indicate that the distribution of runaways electron population undergoes significantly changes, being affected by the island growth and rotation. The combined effect of these mechanisms leads to the formation of a spiral-like structure which distribute the runaway electrons all over the island.
