Disruption Avoidance via RF Current Condensation in Magnetic Islands Produced by Off-Normal Events
A. H. Reiman, N. Bertelli, P. T. Bonoli +5
As tokamaks are designed and built with increasing levels of stored energy in the plasma, disruptions become increasingly dangerous. It has been reported that 95% of the disruption…
Connection between quasi-symmetric magnetic fields and anisotropic pressure equilibria in fusion plasmas
Eduardo Rodriguez, Amitava Bhattacharjee
The stellarator as a concept of magnetic confinement fusion requires careful design to confine particles effectively. A design possibility is to equip the magnetic field with a pro…
Solving the problem of overdetermination of quasisymmetric equilbrium solutions by near-axis expansions. II. Circular axis stellarators
Eduardo Rodriguez, Amitava Bhattacharjee
We apply the near-axis expansion method for quasisymmetric magnetic fields with anisotropic pressure (developed in the companion paper, Part I [E. Rodriguez, A. Bhattacharjee, arXi…
Solving the problem of overdetermination of quasisymmetric equilbrium solutions by near-axis expansions: I. Generalised force balance
Eduardo Rodriguez, Amitava Bhattacharjee
It is well known that the process of construction of quasisymmetric magnetic fields in magnetostatic equilibrium with isotropic pressure suffers from the problem of overdeterminati…
Necessary and Sufficient Conditions for Quasisymmetry
Eduardo Rodriguez, Per Helander, Amitava Bhattacharjee
A necessary and sufficient set of conditions for a quasisymmetric magnetic field in the form of constraint equations is derived from first principles. Without any assumption regard…
Calculating RF current condensation with self-consistent ray-tracing
Richard Nies, Allan H. Reiman, Eduardo Rodriguez +2
By exploiting the nonlinear amplification of the power deposition of RF waves, current condensation promises new pathways to the stabilisation of magnetic islands. We present a num…
