Adjoint approach to calculating shape gradients for three-dimensional magnetic confinement equilibria. Part II: Applications
Elizabeth J. Paul, Thomas Antonsen, Matt Landreman +1
The shape gradient is a local sensitivity function that provides the change in a figure of merit associated with a perturbation to the shape of the object. The shape gradient can b…

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…
