This paper presents the current state of the global gyrokinetic code Orb 5 as an update of the
previous reference (Jolliet et al., 2007). The Orb 5 code solves the electromagnetic Vlasov …

Nonlinear simulations of Alfvén modes (AMs) driven by energetic particles (EPs) in the
presence of turbulence are performed with the gyrokinetic particle-in-cell code ORB5. The …

The interplay between MHD and turbulence is an interesting topic in magnetically confined
plasma and solar plasma. The experimental observations made recently, shown below …

In this work, we use the global electromagnetic and electrostatic gyro kinetic approaches to
investigate the effects of zonal flows forced-driven by Alfv\'en modes due to their excitation …

A large international project, the ITER tokamak [1], currently under construction in France,
aims to demonstrate a significant amount of fusion power, with a goal of achieving …

Tokamak plasmas often present turbulence due to the spatial gradients of density and
temperature. Alfven modes (AMs) are also present, driven unstable by the energetic particle …
