Including the vacuum energy in stellarator coil design
S. Guinchard, S. R. Hudson, E. J. Paul
Being three-dimensional, stellarators have the advantage that plasma currents are not essential for creating rotational-transform; however, the external current-carrying coils in s…

Application of Lagrangian techniques for calculating the on-axis rotational transform
S. Guinchard, W. Sengupta, S. R. Hudson
The Floquet exponents of periodic field lines are studied through the variations of the magnetic action on the magnetic axis, which is assumed to be elliptical. The near-axis forma…
