Combined plasma-coil optimization algorithms
Sophia A. Henneberg, Stuart R. Hudson, David Pfefferlé +1
Combined plasma-coil optimization approaches for designing stellarators are discussed and a new method for calculating free-boundary equilibria is proposed. Four distinct categorie…
Non-planar elasticae as optimal curves for the magnetic axis of stellarators
David Pfefferlé, Lee Gunderson, Stuart R. Hudson +1
The problem of finding an optimal curve for the target magnetic axis of a stellarator is addressed. Euler-Lagrange equations are derived for finite length three-dimensional curves…
Differential formulation of the gyrokinetic Landau operator
Eero Hirvijoki, Alain J. Brizard, David Pfefferlé
Subsequent to the recent rigorous derivation of an energetically consistent gyrokinetic collision operator in the so-called Landau representation, this paper investigates the possi…
Hybrid guiding-centre/full-orbit simulations in non-axisymmetric magnetic geometry exploiting general criterion for guiding-centre accuracy
David Pfefferlé, Jonathan P. Graves, Wilfred A. Cooper
To identify under what conditions guiding-centre or full-orbit tracing should be used, an estimation of the spatial variation of the magnetic field is proposed, not only taking int…
