Plasma wall interactions in RFX-mod with virtual magnetic boundary

A cross-check analysis of the plasma wall interaction in RFX-mod is presented. Different methods to determine the footprint of the interaction are compared. The issue is particularly important for the plasma performances, due to the presence of a quasi-stationary distortion of the plasma surface related to the phase locking of the dynamo modes. We show a good agreement between the different analysis and an important reduction of the phenomenon in the discharges with active feedback control of the magnetic boundary.
