Optimization of flux-surface density variation in stellarator plasmas with respect to the transport of collisional impurities
Stefan Buller, Håkan M. Smith, Albert Mollén +2
Avoiding impurity accumulation is a requirement for steady-state stellarator operation. The accumulation of impurities can be heavily affected by variations in their density on the…
Effect of a weak ion collisionality on the dynamics of kinetic electrostatic shocks
Andréas Sundström, James Juno, Jason M. TenBarge +1
In strictly collisionless electrostatic shocks, the ion distribution function can develop discontinuities along phase-space separatrices, due to partial reflection of the ion popul…
Proton Acceleration in a Laser-induced Relativistic Electron Vortex
Longqing Yi, István Pusztai, Alexander Pukhov +2
We show that when a solid plasma foil with a density gradient on the front surface is irradiated by an intense laser pulse at a grazing angle, around 80 degrees, a relativistic ele…
Collisional transport of impurities with flux-surface varying density in stellarators
S. Buller, H. M. Smith, P. Helander +3
High-Z impurities in magnetic confinement devices are prone to develop density variations on the flux-surface, which can significantly affect their transport. In this paper, we gen…
First principles of modelling the stabilization of microturbulence by fast ions
George J. Wilkie, Aylwin Iantchenko, Ian G. Abel +2
The observation that fast ions stabilize ion-temperature-gradient-driven microturbulence has profound implications for future fusion reactors. It is also important in optimizing th…
