Understanding and Quantifying Banana Coil Magnetic Fields and Forces for Enhanced Optimisation
Annika Zettl, Tobias Schuett, Sophia Henneberg
The optimised tokamak-stellarator hybrid concept (Henneberg and Plunk 2024) has the potential to combine tokamak and stellarator advantages to achieve magnetically confined fusion.…
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…
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…
Exploring novel compact quasi-axisymmetric stellarators
Tobias M. Schuett, Sophia A. Henneberg
The new class of compact quasi-axisymmetric stellarators with a wide range of field periods offers the unique potential to combine the advantages of the two leading magnetic confin…
A compact stellarator-tokamak hybrid
S. A. Henneberg, G. G. Plunk
Tokamaks and stellarators are the leading two magnetic confinement devices for producing fusion energy, begging the question of whether the strengths of the two could be merged int…
Quasi-isodynamic stellarators with low turbulence as fusion reactor candidates
Alan G. Goodman, Pavlos Xanthopoulos, Gabriel G. Plunk +7
The stellarator is a type of fusion energy device that - if properly designed - could provide clean, safe, and abundant energy to the grid. To generate this energy, a stellarator m…
