Linear gyrokinetic investigation of the geodesic acoustic modes in realistic tokamak configurations
I. Novikau, A. Biancalani, A. Bottino +7
Geodesic acoustic modes (GAMs) are studied by means of the gyrokinetic global particle-in-cell code ORB5. Linear electromagnetic simulations in the low electron beta limit have bee…
Tractable flux-driven temperature, density, and rotation profile evolution with the quasilinear gyrokinetic transport model QuaLiKiz
J Citrin, C Bourdelle, F J Casson +14
Quasilinear turbulent transport models are a successful tool for prediction of core tokamak plasma profiles in many regimes. Their success hinges on the reproduction of local nonli…
Centrifugal instability in the regime of fast rotation
Renaud Gueroult, Jean-Marcel Rax, Nathaniel J. Fisch
Centrifugal instability, which stems from a difference between the azimuthal angular drift velocity of ions and electrons, is studied in the limit of fast rotation for which ions c…
Harnessing mass differential confinement effects in magnetized rotating plasmas to address new separation needs
Renaud Gueroult, Jean-Marcel Rax, Stewart J. Zweben +1
The ability to separate large volumes of mixed species based on atomic mass appears desirable for a variety of emerging applications with high societal impact. One possibility to m…
Alternative derivation of exact law for compressible and isothermal magnetohydrodynamics turbulence
Nahuel Andrés, Fouad Sahraoui
The exact law for fully developed homogeneous compressible magnetohydrodynamics (CMHD) turbulence is derived. For an isothermal plasma, without the assumption of isotropy, the exac…
Counter-propagating radiative shock experiments on the Orion laser
F. Suzuki-Vidal, T. Clayson, G. F. Swadling +18
We present new experiments to study the formation of radiative shocks and the interaction between two counter-propagating radiative shocks. The experiments were performed at the Or…
