Nonlinear Landau Collisions Without Collision Tensors
R. Jorge, B. Herfray, C. Vega +1
Far-from-equilibrium plasmas require nonlinear Coulomb collisions, but direct three-dimensional Hermite discretization of the Landau operator needs an impractical dense tensor. By…
Direct Microstability Optimization of Stellarator Devices
R. Jorge, W. Dorland, P. Kim +4
Turbulent transport is regarded as one of the key issues in magnetic confinement nuclear fusion, both for tokamaks in stellarators. In this work, we show that a significant decreas…
Direct construction of stellarator-symmetric quasi-isodynamic magnetic configurations
Katia Camacho Mata, Gabriel G. Plunk, Rogerio Jorge
We develop the formalism of the first order near-axis expansion of the MHD equilibrium equations described in Garren & Boozer (1991), Plunk et al. (2019) and Plunk et al. (2021), f…
A single-field-period quasi-isodynamic stellarator
R. Jorge, G. G. Plunk, M. Drevlak +4
A single-field-period quasi-isodynamic stellarator configuration is presented. This configuration, which resembles a twisted strip, is obtained by the method of direct construction…
Development of Advanced Linearized Gyrokinetic Collision Operators Using a Moment Approach
B. J. Frei, J. Ball, A. C. D. Hoffmann +3
The derivation and numerical implementation of a linearized version of the gyrokinetic (GK) Coulomb collision operator (Jorge R. et al., J. Plasma Phys. 85, 905850604 (2019)) and o…
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…
