SUMMARY:Understanding and optimising magnetic topology in the stellarator 
 edge
DESCRIPTION:Robert Davies (Max Planck Institute for Plasma Physics)\n\nMag
 netic confinement fusion relies on confining a plasma (consisting of hydro
 gen ions and electrons) using carefully-designed magnetic fields, and heat
 ing to fusion-relevant temperatures. In steady state, a reactor would be c
 onstantly producing heat and helium “ash”, which steadily leaks out of the
  confining magnetic field and must be suitable handled; plasma-facing comp
 onents must not be excessively damaged and helium must not be allowed to b
 uild up and choke the confined plasma. This gives rise to an interesting (
 and currently open) research question: how can the magnetic field in the e
 dge of a stellarator be best designed to manage the exhaust?\n\nWe develop
  computationally fast tools to characterise the magnetic structure in the 
 edge of stellarators, in particular, magnetic X/O points and the manifolds
  which act as primary transport pathways for plasma heat and particles. In
  this talk we describe the development of these tools and their applicatio
 n, specifically: (1) application to understanding existing stellarator exp
 eriments and finding interesting and experimentally interesting magnetic c
 onfigurations; (2) development of optimisation schemes, such that magnetic
  structure in new stellarators can be explicitly designed.\n\nDomain: Phys
 ics, Computational Methods and Applied Mathematics\n\nSession Chairs: Flor
 ian Hindenlang (Max Planck Institute for Plasma Physics); Stephan Brunner 
 (EPFL); and Eric Sonnendrücker (Max Planck Institute for Plasma Physics, T
 echnical University of Munich)\n\n
