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 …

A detailed description of GENE-3D, a newly developed global stellarator version of the well
established gyrokinetic turbulence code GENE, is provided–along with some initial …

This work is based on the variational principle for magnetic field lines introduced in 1983 by
Cary and Littlejohn. The action principles for magnetic field lines and for Hamiltonian …

ABSTRACT Extended guiding-center Vlasov–Maxwell equations are derived under the
assumption of time-dependent and inhomogeneous electric and magnetic fields that obey …

Long global gyrokinetic turbulence simulations are particularly challenging in situations
where the system deviates strongly from its initial state and when fluctuation levels are high …

While in recent years gyrokinetic simulations have become the workhorse for theoretical
turbulence and transport studies in the plasma core, their application to the edge and scrape …

We derive the balance equation for the Favre averaged angular momentum in toroidal not
necessarily axisymmetric magnetic field equilibria. We find that the components of angular …

A new diagnostic has been developed to investigate the wave-particle interaction in the
phase-space in gyrokinetic particle-in-cell codes. Keeping information about energy transfer …

Over the past decades, multiple gyrokinetic codes have shown to be able to simulate
turbulence and associated transport in the core of Tokamak devices. However, their …

In the context of global gyrokinetic simulations of turbulence using a particle-in-cell
framework, verifying the delta-f assumption with a fixed background distribution becomes …
