Four-dimensional drift-kinetic model for scrape-off layer plasmas
L. M. Perrone, R. Jorge, P. Ricci
A four-dimensional plasma model able to describe the scrape-off layer region of tokamak devices at arbitrary collisionality is derived in the drift-reduced limit. The basis of the…
The Use of Near-Axis Magnetic Fields for Stellarator Turbulence Simulations
R. Jorge, M. Landreman
The design of turbulence optimized stellarators has so far relied on three-dimensional equilibrium codes such as VMEC in order to find the minimum of a given objective function. In…
Magnetic well and Mercier stability of stellarators near the magnetic axis
Matt Landreman, Rogerio Jorge
We have recently demonstrated that by expanding in small distance from the magnetic axis compared to the major radius, stellarator shapes with low neoclassical transport can be gen…
Nonlinear Gyrokinetic Coulomb Collision Operator
R. Jorge, B. J. Frei, P. Ricci
A gyrokinetic Coulomb collision operator is derived, which is particularly useful to describe the plasma dynamics at the periphery region of magnetic confinement fusion devices. Th…
A gyrokinetic model for the plasma periphery of tokamak devices
B. J. Frei, R. Jorge, P. Ricci
A gyrokinetic model is presented that can properly describe strong flows, large and small amplitude electromagnetic fluctuations occurring on scale lengths ranging from the electro…
Linear Theory of Electron-Plasma Waves at Arbitrary Collisionality
R. Jorge, P. Ricci, S. Brunner +5
The dynamics of electron-plasma waves are described at arbitrary collisionality by considering the full Coulomb collision operator. The description is based on a Hermite-Laguerre d…
