Intrinsic Turbulence Stabilization in a Stellarator - Xanthopoulus.pdf
This paper gives information on how the toroidal-poloidal geometry of a stellarator influences the behavior of turbulence and vaguely the behavior of drift waves… Beschreiben Mechanismen, wie Stellarator-Geometrie Drift-Wellen-Turbulenz moduliert und zonale Fluss-Dynamik beeinflusst.
Notes
- The magnetic surfaces of modern stellarators exhibit locally compressed regions of strong turbulence drive, but also intristic mechanisms to mitigate the effects of this drive.
- Geometric properties of a stellarator’s field lines vary greatly over the magnetic surfaces, that are pushed against each other in some locations, resulting in locally large temperature gradients and consequently strong drive for turbulence.
- The generally employed method for calculating turbulence is gyrocinetics (5-dimensional differential equations)
- The paper treats electrons as following an adiabatic Boltzmann Distribution
- In a stellarator, geometric quantities such as magnetic shear and curvature cause the magnetic drift to vary
