Gyrokinetic Field Theory as a Gauge Transform or: gyrokinetic theory without Lie transforms
Bruce D. Scott
Gyrokinetic theory is a basis for treating magnetised plasma dynamics slower than particle gyrofrequencies where the scale of the background is larger than relevant gyroradii. The…
Observation of explosive collisionless reconnection in 3D nonlinear gyrofluid simulations
Alessandro Biancalani, Bruce D. Scott
The nonlinear dynamics of collisionless reconnecting modes is investigated, in the framework of a three-dimensional gyrofluid model. This is the relevant regime of high-temperature…
Energetic Consistency and Momentum Conservation in the Gyrokinetic Description of Tokamak Plasmas
Bruce Scott, Juri Smirnov
Gyrokinetic field theory is addressed in the context of a general Hamiltonian. The background magnetic geometry is static and axisymmetric, and all dependence of the Lagrangian upo…
Nonlinear polarisation and dissipative correspondence between low frequency fluid and gyrofluid equations
Bruce D. Scott
The correspondence between gyrofluid and low frequency fluid equations is examined. The lowest order conservative effects in ExB advection, parallel dynamics, and curvature match t…
Derivation via free energy conservation constraints of gyrofluid equations with finite-gyroradius electromagnetic nonlinearities
Bruce D. Scott
The derivation of electromagnetic gyrofluid equations is made systematic by using the Hermite polynomial form of the underlying delta-f gyrokinetic distribution function. The gyrok…
Flux surface shaping effects on tokamak edge turbulence and flows
Alexander Kendl, Bruce D. Scott
Shaping of magnetic flux surfaces is found to have a strong impact on turbulence and transport in tokamak edge plasmas. A series of axisymmetric equilibria with varying elongation…
