Modification of ∆′ by magnetic feedback and kinetic effects
Journal article, 2012

Two possible ways of modifying the linear tearing mode index, by active magnetic feed- back and by drift kinetic effects of deeply trapped particles, are analytically investigated. Mag- netic feedback schemes, studied in this work, are found generally stabilizing for ∆′ . The drift kinetic effects from both thermal particles and hot ions tend to reduce the power of the large solution from the outer region. This generally leads to a destabilization of ∆′ for the toroidal analytic equilibria considered here.
