Interpreting Radial Correlation Doppler Reflectometry using Gyrokinetic Simulations
J. Ruiz Ruiz, F. I. Parra, V. H. Hall-Chen +12
A linear response, local model for the DBS amplitude applied to gyrokinetic simulations shows that radial correlation Doppler reflectometry measurements (RCDR, Schirmer et al., Pla…
Turbulent transport of impurities in 3D devices
J. M. García-Regaña, M. Barnes, I. Calvo +5
A large diffusive turbulent contribution to the radial impurity transport in Wendelstein 7-X (W7-X) plasmas has been experimentally inferred during the first campaigns and numerica…
Impact of plasma shaping on tokamak microstability
O. Beeke, M. Barnes, M. Romanelli +2
We have used the local- gyrokinetic code GS2 to perform studies of the effect of flux-surface shaping on two highly-shaped, low- and high- JT-60SA-relevant equilibria, inc…
Turbulent impurity transport simulations in Wendelstein 7-X plasmas
J. M. García-Regaña, M. Barnes, I. Calvo +8
A study of turbulent impurity transport by means of quasilinear and nonlinear gyrokinetic simulations is presented for Wendelstein 7-X (W7-X). The calculations have been carried ou…
Toroidal and slab ETG instability dominance in the linear spectrum of JET-ILW pedestals
Jason F. Parisi, Felix I. Parra, Colin M. Roach +9
Local linear gyrokinetic simulations show that electron temperature gradient (ETG) instabilities are the fastest growing modes for in the steep gradient regio…
Ion versus electron heating in compressively driven astrophysical gyrokinetic turbulence
Y. Kawazura, A. A. Schekochihin, M. Barnes +4
The partition of irreversible heating between ions and electrons in compressively driven (but subsonic) collisionless turbulence is investigated by means of nonlinear hybrid gyroki…
