SPECTRE: A robust solver for 3D equilibria with arbitrary topology
E. Balkovic, J. Loizu, E. Lanti +6
SPECTRE is a new computational code that solves three‑dimensional plasma equilibrium problems with arbitrary magnetic topology using a multi‑region relaxed MHD model and a trust‑re…
Polaris: a flexible stellarator demonstration experiment with simple modular coils
Simon P. H. Vincent, Joaquim Loizu, Matthieu Toussaint +14
We present the design, construction, and first plasma experiments of Polaris, a new small-scale stellarator experiment (major radius R ~ 0.4 m) located at the Swiss Plasma Center.…
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…
A topological approach to magnetic nulls
Ben Y. Israeli, Christopher Berg Smiet
Magnetic nulls are locations where the magnetic field vanishes. Nulls are the location of magnetic reconnection, and they determine to a large degree the magnetic connectivity in a…
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…
