On Tor Supra, the ergodic divertor is used to control particle and heat fluxes at the plasma edge. As it turns out, the Ed has also the ability to affect the MHD stability of the plasma equilibrium. In the past, Tore Supra mostly took advantage of the Ed stabilizing influence. However, recent attempts to operate the ED with optimal edge conditions happened to be limited by disruptive events. The interest in extending the operational domain is clear motivation to understand how the observed MHD effects relate to the ED. A tentative analysis is reported in this paper.
