The subtlety of the outermost stellarator magnetic surface
Alkesh Punjabi, Allen H. Boozer
An analytic model of the magnetic field line behavior in a stellarator is used to study the subtlety of the concept of an outermost magnetic surface. The analytic model that we use…
The topology of non-resonant stellarator divertors
Robert Davies, Christopher B. Smiet, Alkesh Punjabi +2
We apply topological methods to better understand how the magnetic field in the stellarator edge can be diverted away from the confined region. Our primary method is calculating th…
A new type of stellarator divertor: the hybrid stellarator divertor
Alkesh Punjabi, Allen H. Boozer
A new type of stellarator divertor is found. It has features of both a nonresonant divertor (A. Punjabi and A. H. Boozer, Phys. Plasmas 27, 012503 (2020)) as well as a resonant div…
Simulation of non-resonant stellarator divertor
Alkesh Punjabi, Allen H. Boozer
An efficient numerical method of studying nonresonant stellarator divertors was introduced in Boozer and Punjabi [Phys. Plasmas 25, 092505 (2018)]. This method is used in this pape…
Magnetic turnstiles in nonresonant stellarator divertor
Alkesh Punjabi, Allen H. Boozer
Non-resonant stellarator divertors have magnetic flux tubes, called magnetic turnstiles, that cross cantori, which are fractal remnants of destroyed invariant tori with holes, that…
Magnetic Barriers and their q95 dependence at DIII-D
F. A. Volpe, J. Kessler, H. Ali +2
It is well known that externally generated resonant magnetic perturbations (RMPs) can form islands in the plasma edge. In turn, large overlapping islands generate stochastic fields…
