Effect of drifts on SOL plasma in DTT Double Null configuration

Extreme conditions are predicted for the next generation devices as DEMO that can cause severe damages to the plasma facing components (PFCs). Possible benefits could arise from the adoption of Alternative divertor Configurations (ADCs) [1,2] which are currently under investigation. In particular, the Double Null configuration represents one of the possible candidates, as shown for instance in numerical studies performed with SOLDEGE2DEIRENE [3]. Drifts can play an important role in determining the actual Scrape-Off Layer (SOL) conditions by acting on the plasma transport and detachment as seen in the present device[4-7]. In this contribution, we will discuss the role of the drifts in a Connected Double Null (CDN) configuration in DTT (Divertor Test Tokamak) [8] by analyzing the change in the divertor plasma conditions and the effect on the power asymmetry.
