"Theoretical Description of Heavy Impurity Transport and its Application to the Modelling of Tungsten in JET and ASDEX Upgrade"

F.J. Casson C. Angioni E.A. Belli R. Bilato P. Mantica T. Odstrcil T Puetterich M. Valisa L. Garzotti C. Giroud J. Hobirk C.F. Maggi J. Mlynar M.L. Reinke JET EFDA contributors ASDEX-Upgrade team

The effects of poloidal asymmetries and heated minority species are shown to be necessary to accurately describe heavy impurity transport in present experiments in JET and ASDEX Upgrade. Plasma rotation, or any small background electrostatic field in the plasma, such as that generated by anisotropic external heating can generate strong poloidal den…

"Modelling Toroidal Rotation Damping in ITER Due to External 3D Fields"

Y. Liu R. Akers I.T. Chapman Y. Gribov G.Z. Hao G.T.A. Huijsmans A. Kirk A. Loarte S.D. Pinches M. Reinke D. Ryan Y. Sun Z.R. Wang

The linear and quasi-linear plasma response to the n = 3 and n = 4 (n is the toroidal mode number) resonant magnetic perturbation (RMP) fields, produced by the in-vessel edge localized mode control coils, is numerically studied for an ITER 15MA H-mode baseline Scenario. Both single fluid and fluid-kinetic hybrid models are used. The inclusion of dr…

"Effects of Magnetic Shear on Toroidal Rotation in Tokamak Plasmas with Lower Hybrid Current Drive"

J. E. Rice Y. A. Podpaly M. L. Reinke R. Mumgaard S. D. Scott S. Shiraiwa G. M. Wallace B. Chouli C. Fenzi-Bonizec M. F. F. Nave P. H. Diamond C. Gao R. S. Granetz J.W. Hughes R. R. Parker Et Al

Application of lower hybrid (LH) current drive in tokamak plasmas can induce both co- and countercurrent directed changes in toroidal rotation, depending on the core q profile. For discharges with q0 < 1, rotation increments in the countercurrent direction are observed. If the LH-driven current is sufficient to suppress sawteeth and increase q0 abo…
