Abstract Resilient divertor features connected to open chaotic edge structures in the Helically Symmetric eXperiment are investigated. For first time, an expanded vessel wall was considered that would give space for implementation of a physical target structure. The analysis done four different magnetic configurations with very plasma edges. A resilient interaction pattern identified across all configurations. This manifests as qualitatively similar footprint behavior equilibria. Overall,...
Abstract The design of divertor targets and baffles for optimal heat particle
exhaust from magnetically confined fusion plasmas requires a combination fast,
low-fidelity models (such as EMC3-Lite [1]) scoping studies high-fidelity ones
(such EMC3-EIRENE [2]) verification. Both those approaches benefit a
magnetic flux tube mesh fast interpolation mapping field line segments [3]. A
new automated generator unstructured quadrilateral tubes with...
Non-resonant divertors (NRDs) separate the confined plasma from surrounding facing components (PFCs). The resulting striking field line intersection pattern on these PFCs is insensitive to equilibrium effects. However, a complex scrape-off layer (SOL), created by chaotic magnetic topology in edge, connects core through varying flux tubes. Compact Toroidal Hybrid (CTH) serves as test-bed study this scanning across its inductive current. Simulations observe significant change of edge structure...
Abstract We present a semi-automated algorithm for designing three-dimensional divertor or limiter plates targeting low heat loads. The designs the in two stages: Firstly, parallel flux distribution is caught on vertically-inclined at one several toroidal locations. Secondly, power per unit area reduced by stretching, tilting and bending toroidally. Heat transport modeled using EMC3-Lite code, which uses an anisotropic diffusion model.
We apply this scheme to HSX, medium-sized...
