Characterisation of X- and O-points in Wendelstein 7-X with respect to coil currents
Robert Davies, Christopher B. Smiet, Charlotte Batzdorf +3
This work analyses vacuum magnetic field topology in Wendelstein 7-X (W7-X) with respect to changes in the current in the superconducting coils. We develop a fast automated scheme…
Surfaces with Klein bottle topology occur in fusion reactor fields
Christopher Berg Smiet
Magnetic confinement fusion devices, such as tokamaks and stellarators, are designed such that magnetic field lines lie in magnetic surfaces that form a foliation of nested genus-1…
Turnstile area as a measure for chaotic transport in magnetic confinement fusion devices
Christopher Berg Smiet, Ludovic Rais, Joaquim Loizu +1
We analyze stochasticity in the magnetic fields of magnetic confinement fusion reactors by calculating the lobe areas of turnstiles - a method developed for characterizing transpor…
The topology of non-resonant stellarator divertors
Robert Davies, Christopher B. Smiet, Alkesh Punjabi +2
We apply topological methods to better understand how the magnetic field in the stellarator edge can be diverted away from the confined region. Our primary method is calculating th…
