Accelerated methods for direct computation of fusion alpha particle losses within, stellarator optimization

Journal of Plasma Physics, 2020
Accelerated statistical computation of collisionless fusion alpha particle losses in stellarator configurations is presented based on direct guiding-centre orbit tracing. The approach relies on the combination of recently developed symplectic integrators

The scoping, design, and plasma physics optimization of the Eos neutron source stellarator

Nuclear Fusion
On the path to a fusion pilot plant, Thea Energy plans to build Eos, a sub-breakeven, deuterium-deuterium, beam-target fusion, stellarator neutron source facility for producing tritium and other valuable radioisotopes.

Development of Advanced Stellarator With Identical Permanent Magnet Blocks

Social Science Research Network, 2021
Stellarator offers an attractive approach to fusion energy, but difficulties in fabricating and assembling complicated 3D coils with tight tolerance requirements severely retard its development.

ConStellaration: A dataset of QI-like stellarator plasma boundaries and optimization benchmarks

arXiv.org
Stellarators are magnetic confinement devices under active development to deliver steady-state carbon-free fusion energy. Their design involves a high-dimensional, constrained optimization problem that requires expensive physics simulations and ...

Benign Saturation of Ideal Ballooning Instability in a High-Performance Stellarator.

Physical Review Letters
To examine the robustness of the designed 5% β limit for high-performance operation in the W7-X stellarator, we undertake nonlinear magnetohydrodynamic (MHD) simulations of pressure-driven instabilities using the m3d-c1 code.

Near-axis description of stellarator-symmetric quasi-isodynamic stellarators to second order

Journal of Plasma Physics
The near-axis description of optimised stellarators, at second order in the expansion, provides important information about the field, both of physical and practical importance for stellarator optimisation.

Stellar Radii

Symposium - International Astronomical Union, 1997
Observing a stellar radius basically means observing a center-to-limb intensity variation. The significance and properties of center-to-limb variations, common approximations, the correlation with optical-depth radii in extended-photophere stars, and direct measurements of angular (interferometry, lunar occultation) and absolute diameters (binary ...
