Curl-free magnetic fields for stellarator optimization

Posted by in category: physics

O.o.


This paper describes a new and efficient method of defining an annular region of a curl-free magnetic field with specific physics and coil properties that can be used in stellarator design. Three statements define the importance:

Codes can follow an optimized curl-free initial state to a final full-pressure equilibrium. The large size of the optimization space of stellarators.

Approximately fifty externally-produced distributions of magnetic field, makes success in finding a global optimum largely determined by the starting point.

The design of a stellarator is actually improved when the central region of the plasma has rapid transport with the confinement provided by a surrounding annulus of magnetic surfaces with low transport.
