We show that a class of near-marginal and low-collisional magnetised plasmas naturally
evolve into a globally organised state dubbed the'$\mathbf {E}\times\mathbf {B} $ staircase' …

The formation mechanism of internal transport barriers (ITBs) in flux-driven turbulence is
studied by means of the full-f gyrokinetic code GKNET. In the adiabatic electron case with a …

Flux-driven global gyrokinetic codes are now mature enough to make predictions in terms of
turbulence and transport in tokamak plasmas. Some of the recent breakthroughs of three …
