Magnetic shear effects on ballooning turbulence in the boundary of fusion devices

arXiv:2508.04881v1 Announce Type: new
Abstract: The effect of magnetic shear on ballooning-driven plasma edge turbulence is studied through nonlinear simulations complemented by linear numerical and analytical investigations. Nonlinear, 3D, global, flux-driven simulations using the GBS code show that the scale separation between radial, x, and poloidal, y, size of turbulent eddies, kx
