Electrostatic stability of electron-positron plasmas in dipole geometry
Alexey Mishchenko, Gabriel Plunk, Per Helander
The electrostatic stability of electron-positron plasmas is investigated in the point-dipole and Z-pinch limits of dipole geometry. The kinetic dispersion relation for sub-bounce-f…
Collisionless microinstabilities in stellarators. IV. The ion-driven trapped-electron mode
G. G. Plunk, J. W. Connor, P. Helander
Optimised stellarators and other magnetic-confinement devices having the property that the average magnetic curvature is favourable for all particle orbits are called maximum- d…
On the scaling of ion and electron temperature gradient driven turbulence in slab geometry
G. G. Plunk
We demonstrate that the scaling properties of slab ion and electron temperature gradient driven turbulence may be derived by dimensional analysis of a drift kinetic system with one…
Distinct turbulence saturation regimes in stellarators
G. G. Plunk, P. Xanthopoulos, P. Helander
In the complex 3D magnetic fields of stellarators, ion-temperature-gradient turbulence is shown to have two distinct saturation regimes, as revealed by petascale numerical simulati…
Nonlinear growth of zonal flows by secondary instability in general magnetic geometry
G. G. Plunk, A. Bañón Navarro
We present a theory of the nonlinear growth of zonal flows in magnetized plasma turbulence, by the mechanism of secondary instability. The theory is derived for general magnetic ge…
