A novel computation of the linear plasma response to a resonant error field in single-fluid rotating visco-resistive MHD
Paolo Zanca
This paper reexamines the linear plasma response to a static resonant error field (EF) in the single-fluid rotating visco-resistive magneto-hydrodinamic (MHD). A tearing-mode stabl…
A unified model of density limit in fusion plasmas
P. Zanca, F. Sattin, D. F. Escande +2
A limit for the edge density, ruled by radiation losses from light impurities, is established by a minimal cylindrical magneto-thermal equilibrium model. For ohmic tokamak and reve…
An active feedback recovery technique from disruption events induced by m=2 n=1 tearing modes in ohmically heated tokamak plasmas
P. Zanca, R. Paccagnella, C. Finotti +6
We present experimental results of magnetic feedback control on the m=2, n=1 tearing mode in RFX-mod operated as a circular ohmically heated tokamak. The feedback suppression of th…
Equilibrium reconstruction for Single Helical Axis reversed field pinch plasmas
Emilio Martines, Rita Lorenzini, Barbara Momo +8
Single Helical Axis (SHAx) configurations are emerging as the natural state for high current reversed field pinch (RFP) plasmas. These states feature the presence of transport barr…
Reconstruction of the magnetic perturbation in a toroidal force-free circular plasma: application to the Reversed Field Pinch
David Terranova, Paolo Zanca
A new method to obtain the radial profile of the magnetic perturbation in a toroidal force-free plasma having circular cross section is developed. The method is quite general and c…
An equilibrium model for RFP plasmas in the presence of resonant tearing modes with an application to particle and heat transport
P. Zanca, F. Sattin, E. Martines
The equilibrium of a finite-beta cylindrical RFP plasma in the presence of saturated-amplitude tearing modes is investigated. The singularities arising from the perturbative analys…
