The topology of non-resonant stellarator divertors
Nuclear FusionWe 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 the winding numbers of closed contours, which gives information on the ...

Collisionless microinstabilities in stellarators II- numerical simulations [PDF]
, 2013 Microinstabilities exhibit a rich variety of behavior in stellarators due to the many degrees of freedom in the magnetic geometry. It has recently been found that certain stellarators (quasi-isodynamic ones with maximum-J geometry) are partly resilient ...

Stellar Magnetism affects all spectral types and exists and varies throughout the evolution of stars. Magnetic fields can affect not only the interior of stars, but also their circumstellar environments. In this chapter, we concentrate on the magnetic fields that can be measured at the surface of stars through the influence of the Zeeman effect on ...

A theory of the high-mode phenomenon for stellarators [PDF]
, 1995 It is shown that besides the ion orbit loss mechanism, which occurs in a region a {minus} {var_epsilon}{sub t}{rho}{sub p} < r < a, the collisionless drift-orbit transport flux can also drive the poloidal {rvec E} {times} {rvec B} velocity in a region r <

Results from helical axis stellarators [PDF]
, 2001 Helical axis stellarators produce magnetic surfaces of high rotational transform and moderate shear solely by means of external currents, with the promise of high b.

Tools for designing the next generation of stellarators [PDF]
, 2020 Experience in the construction of optimized stellarators shows the coil system is a significant challenge. The precision necessary allow the generation of accurate flux surfaces in recent experiments affected both cost and schedule negatively.

Quasi-single-stage optimization for permanent magnet stellarators
Nuclear FusionAdvanced stellarators are typically optimized in two stages. The plasma equilibrium is optimized first, followed by the design of coils/permanent magnets.
