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…
Surface Current Optimization and Coil-Cutting Algorithms for Stage-Two Stellarator Optimization
Dario Panici, Rory Conlin, Rahul Gaur +8
Stellarator optimization often takes a two-stage approach, where in the first stage the boundary is varied in order to optimize for some physics metrics, while in the second stage…
Enhancing Stellarator Accessibility through Port Size Optimization
A. Baillod, E. J. Paul, T. Elder +1
Access to the plasma chamber in a stellarator reactor is essential for maintenance and diagnostics. However, the complex geometry of stellarator coils, often characterized by their…
Current potential patches
Todd Elder, Allen H Boozer
A novel form of the current potential, a mathematical tool for the design of stellarators and stellarator coils, is developed. Specifically, these are current potentials with a fin…
Example of exponentially enhanced magnetic reconnection driven by a spatially-bounded and laminar ideal flow
Allen H Boozer, Todd Elder
In laboratory and natural plasmas of practical interest, the spatial scale at which magnetic field lines lose distinguishability differs enormously from the scale of magn…
Magnetic nulls in interacting dipolar fields
Todd Elder, Allen H. Boozer
The prominence of nulls in reconnection theory is due to the expected singular current density and the indeterminacy of field-lines at a magnetic null. Electron inertia changes the…
Impact of a minority relativistic electron tail interacting with a thermal plasma containing high-atomic-number impurities
Nathan A. Garland, Hyun-Kyung Chung, Christopher J. Fontes +6
A minority relativistic electron component can arise in both laboratory and naturally-occurring plasmas. In the presence of high-atomic-number ion species, the ion charge state dis…
