"Electromagnetic Effects in the Stabilization of Turbulence by Sheared Flow"

M.D.J. Cole S.L. Newton S.C. Cowley N.F. Loureiro D. Dickinson C. Roach J.W. Connor

We have extended our study of the competition between the drive and stabilization of plasma microinstabilities by sheared flow to include electromagnetic effects at low plasma ß (the ratio of plasma to magnetic pressure). The extended system of characteristic equations is formulated, for a dissipative fluid model developed from the gyrokinetic equ…

"Physics of Penetration of Resonant Magnetic Perturbations Used for Type I Edge Localized Modes Suppression in Tokamaks."

M. Bécoulet G. Huysmans X. Garbet E. Nardon D. Howell A.Garofalo M. Schaffer T. Evans K. Shaing A. Cole J.-K. Park P. Cahyna

Non-linear reduced MHD modelling of the response of a toroidally rotating plasma on Resonant Magnetic Perturbations (RMPs) is presented for DIII-D and ITER typical parameter. The non-linear cylindrical reduced MHD (RMHD) code was adapted to take into account toroidal rotation and plasma braking mechanisms such as resonant braking (~jxB) and the Neo…
