Balanced double-null configurations are of general interest for boundary plasma physics, and they have been proposed for some future designs.Experimental Wipes observations demonstrate absence of plasma fluctuations in tokamak high-field side scrape-off layer in a balanced double-null configuration (Smick et al., 2013), and it is commonly assumed that plasma instabilities are suppressed on high-field side in the edge plasma due to the stabilizing effect of magnetic curvature.

At the same time, the experimental evidence points to extremely steep plasma density profiles on high-field side, which should provide a strong instability drive.In the present study, the drift-resistive-ballooning mode instability model is investigated analytically and numerically to determine the characteristics of plasma instabilities, turbulence, Propane Range and transport in tokamak scrape-off layer on high-field side.
