High-n Ideal TAE Stability of ITER
The ideal MHD stability analysis of high-n (n is the toroidal mode number) Toroidal Alfvén Eigenmodes (TAE’s) is presented, using realistic and completely general ITER equilibria with shaped, up-down asymmetric, magnetic flux surfaces. An approach has been used, based on analytical-theoretical methods, which can give interesting results and allows us to analyze the conditions for enhanced TAE d...
متن کاملLimits of filopodium stability.
Filopodia are long, fingerlike membrane tubes supported by cytoskeletal filaments. Their shape is determined by the stiffness of the actin filament bundles found inside them and by the interplay between the surface tension and bending rigidity of the membrane. Although one might expect the Euler buckling instability to limit the length of filopodia, we show through simple energetic consideratio...
متن کاملIT/P6-14 Pedestal Stability Comparison and ITER Pedestal Prediction
The pressure at the top of the edge transport barrier (or “pedestal height”) strongly impacts fusion performance, while large edge localized modes (ELMs), driven by the free energy in the pedestal region, can constrain material lifetimes. Accurately predicting the pedestal height and ELM behavior in ITER is an essential element of prediction and optimization of fusion performance. Investigation...
متن کاملGlobal gyrokinetic ion temperature gradient turbulence simulations of ITER
Global gyrokinetic simulations of ion temperature gradient (ITG) driven turbulence in an ideal MHD ITER equilibrium plasma are performed with the ORB5 code. The noise control and field-aligned Fourier filtering procedures implemented in ORB5 are essential in obtaining numerically healthy results with a reasonable amount of computational effort: typical simulations require 109 grid points, 109 p...
