Effect of magnetic perturbations on the 3D MHD self-organization of shaped tokamak plasmas

With this internal note we want to make available to the RFX colleagues the study performed for the invited talk "Effect of helical magnetic perturbations on the 3D MHD self-organization of fusion plasmas" given by D. Bonfiglio at the 7th IAEA Technical Meeting on "Theory of Plasmas Instabilities" held in Frascati, Italy on 4-6 March 2015. The proceeding papers of invited and contributed talks, including a version of this internal note, will be published on the conference website http://www.iaeatm-inst2015.enea.it/
