Effective Critical Electric Field for Runaway-Electron Generation
Adam Stahl, Eero Hirvijoki, Joan Decker +2
In this Letter we investigate factors that influence the effective critical electric field for runaway-electron generation in plasmas. We present numerical solutions of the kinetic…
Universal instability for wavelengths below the ion Larmor scale
Matt Landreman, Thomas M Antonsen, William Dorland
We demonstrate that the universal mode driven by the density gradient in a plasma slab can be absolutely unstable even in the presence of reasonable magnetic shear. Previous studie…
Less constrained omnigeneous stellarators
Felix I. Parra, Ivan Calvo, Per Helander +1
A stellarator is said to be omnigeneous if all particles have vanishing average radial drifts. In omnigeneous stellarators, particles are perfectly confined in the absence of turbu…
