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…

Magnetic Field Line Chaos, Cantori, and Turnstiles in Toroidal Plasmas

Allen H Boozer

The mathematical concepts of chaos, cartori, and turnstiles underlie a number of areas of tokamak and stellarator physics. Nevertheless, these concepts have seldom explicitly appea…

Electron Inertia and Magnetic Reconnection

Allen H Boozer

When electron inertia is the only non-ideal effect in the evolution of a magnetic field , the field lines of reconnect, but the lines of a related field $\vec{\m…

Constraints on the magnetic field evolution in tokamak power plants

Allen H Boozer

Forty-five years ago a coordinate system was shown to exist that gave simple but exact expressions whenever and wherever a toroidal plasma equilibrium $\vec{\nabla}p=\vec{j}\times\…

Efficient analysis of magnetic field line behavior in toroidal plasmas

Allen H Boozer

The confinement of plasmas in tokamaks and stellarators depends on magnetic field lines lying in nested toroidal surfaces. The transition near the plasma edge away from the lines l…

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…
