Toroidal asymmetries in divertor impurity influxes in NSTX

Toroidal asymmetries in divertor impurity influxes in NSTX

Toroidal asymmetries in divertor carbon and lithium influxes were observed in NSTX, due to toroidal differences in surface composition, tile leading edges, externally-applied three-dimensional (3D) fields and toroidally-localized edge plasma modifications due to radio frequency heating.
