Divertor topology and vacuum vessel design for stellarators
Andrew Giuliani, Raffael Wendlinger, Misha Padidar +4
The paper introduces algorithms for jointly optimizing stellarator edge magnetic structures and vacuum vessel shapes, enabling various divertor configurations—including precise sno…
Computational studies of giant edge islands and unpaired X-points in HSX and W7-X by manipulating coil currents
Robert Davies, Dieter Boeyaert, Alexis Wolfmeister +3
The authors show that lowering specific coil currents in the HSX and W7‑X stellarators creates unusually large edge magnetic island chains and unpaired X‑points, and they use the E…
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…
Stellarator divertor design by optimizing coils for surfaces with sharp corners
Todd Elder, Matt Landremann, Christoper B. Smiet +1
In stellarators, achieving effective divertor configurations is challenging due to the three-dimensional nature of the magnetic fields, which often leads to chaotic field lines and…
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…
