Abstract

A five-point model for the scrape-off layer and divertor plasmas has been developed to study the inside/outside divertor asymmetry induced by the divertor biasing. Effects of divertor biasing on the asymmetry are studied for low and high recycling states. In the low recycling, the biasing has a little influence on the asymmetry. On the other hand, in the high recycling, the biasing substantially controls the asymmetry. The divertor plasma has higher density and lower temperature at the anode-side plate compared with those at the cathode-side plate.
