Facilities for Quasi-Axisymmetric Stellarator Research
Authors: G.H. Neilson, et. al.
Abstract:
The quasi-axisymmetric (QA) stellarator, a
three-dimensional magnetic configuration with close
connections to tokamaks, offers solutions for a steady-state,
disruption-free fusion system. A new experimental facility,
QUASAR, provides a rapid approach to the next step in QA
development, an integrated experimental test of its physics
properties, taking advantage of the designs, fabricated
components, and detailed assembly plans developed for the
NCSX project. A scenario is presented for constructing the
QUASAR facility for physics research operations starting in
2019. A facility for the step beyond QUASAR, performance
extension to high temperature, high pressure sustained
plasmas is described. Operating in DD, such a facility would
investigate the scale-up in size and pulse length from
QUASAR, while a suitably equipped version operating in DT
could address fusion nuclear missions, with operation starting
in 2027.
