Optimization of stellarator configurations combining omnigenity and piecewise omnigenity
Hengqian Liu, Guodong Yu, José Luis Velasco +1
We present a method for optimizing stellarator configurations that combine omnigenity and piecewise omnigenity (pwO). Within the \texttt{OOPS} optimization framework [Liu \textit{e…

Stellarator impurity flux driven by electric fields tangent to magnetic surfaces
Ivan Calvo, Felix I. Parra, J. L. Velasco +2
The control of impurity accumulation is one of the main challenges for future stellarator fusion reactors. The standard argument to explain this accumulation relies on the, in prin…
