“…First, small variations in the magnetic balance near the DN shape have sizable effects on the poloidal distributions of heat and particle fluxes at the divertor targets [2,3], the edge localized mode (ELM)-driven particle pulses at the divertor targets [4] and the poloidal distribution of plasma recycling [5]. Second, ion particle drifts in the scrape-off layer (SOL) and divertor(s), such as B × ∇B and E × B drifts [6][7][8], also contribute to the formation of these poloidal 'asymmetries' [9,10]. The particle flows that result from these drifts have long been suspected of playing important roles in edge-and divertor plasma behaviour and are being actively investigated, e.g.…”
