A Weakly Nonlinear Theory of Zonal-Flow Forcing in Gyrokinetic Turbulence
Georgia Acton, Eduardo Rodrìguez, Gareth Roberg-Clark +1
The forced generation of zonal flows by microinstability-driven turbulence is investigated within the framework of local gyrokinetic theory far from marginality. We use a numerical…
Near-axis quasi-isodynamic database
Eduardo Rodriguez, Gabriel G. Plunk
In this work, we investigate the landscape of quasi-isodynamic stellarators using the near-axis expansion of the magnetic field. Building on recent theoretical developments, we con…
A geometric approach to constructing quasi-isodynamic fields
G. G. Plunk, E. RodrÃguez
The near-axis theory for quasi-isodynamic stellarator equilibria is reformulated in terms of geometric inputs, to allow greater control of the ``direct construction'' of quasi-isod…
Near-axis measures of quasi-isodynamic configurations
Eduardo Rodriguez, Gabriel G Plunk
We present a number of measures and techniques to characterise and effectively construct quasi-isodynamic stellarators within the near-axis framework, without the need to resort to…
Near-axis description of stellarator-symmetric quasi-isodynamic stellarators to second order
Eduardo Rodriguez, Gabriel G. Plunk, Rogerio Jorge
The near-axis description of optimised stellarators, at second order in the expansion, provides important information about the field, both of physical and practical importance for…
