Optical analogy for stellarators: Ridges as caustics and coils as singularities
Wrick Sengupta, Stefan Buller, Rogerio Jorge +7
A common feature of most numerically optimized stellarator geometries is the presence of sharp ridges on outer flux surfaces, irrespective of the rotational transform. Despite thei…

How Does The Magnetic Gradient Scale Length Influence Complexity of Filamentary Coils in Stellarators?
John Kappel, Matt Landreman, Philipp JuraÅ¡iÄ +1
The distance between the last closed flux surface (LCFS) and the nearest electromagnetic coils is a dominating factor in the cost, size, and engineering difficulty of stellarators.…
