Scalar curvature deformations with non-compact boundaries
Helge Frerichs
We develop a general deformation principle for families of Riemannian metrics on smooth manifolds with possibly non-compact boundary, preserving lower scalar curvature bounds. The…

Resilient Stellarator Divertor Characteristics in the Helically Symmetric eXperiment
K. A. Garcia, A. Bader, D. Boeyaert +5
Resilient divertor features connected to open chaotic edge structures in the Helically Symmetric Experiment (HSX) are investigated. For the first time, an expanded vessel wall was…

Magnetic mesh generation and field line reconstruction for scrape-off layer and divertor modeling in stellarators
H. Frerichs, D. Boeyaert, Y. Feng +1
The design of divertor targets and baffles for optimal heat and particle exhaust from magnetically confined fusion plasmas requires a combination of fast, low-fidelity models (such…
