Suppression of large edge-localized modes in high-confinement DIII-D plasmas with a stochastic magnetic boundary.
Todd Evans,R.A. Moyer,P R Thomas,J.G. Watkins,T.H. Osborne,Jose Boedo,E. J. Doyle,Max E. Fenstermacher,K.H. Finken,R. J. Groebner,M. Groth,J. H. Harris,R.J. La Haye,C.J.

TL;DR: Stochastic boundaries are compatible with H modes and may be attractive for ELM control in next-step fusion tokamaks, and the H mode transport barrier and core confinement are unaffected by the stochastic boundary.
Journal ArticleDOI

Todd Evans,R.A. Moyer,J.G. Watkins,T.H. Osborne,P.R. Thomas,M. Becoulet,Jose Boedo,E. J. Doyle,M.E. Fenstermacher,K.H. Finken,R. J. Groebner,M. Groth,J. H. Harris,G.L. Jackson,R.J. La Haye,C.J.

TL;DR: In this paper, the authors demonstrate that non-axisymmetric edge magnetic perturbations provide a very attractive development path for active ELM control in future tokamaks such as ITER.
Journal ArticleDOI
Plasmas as antennas: Theory, experiment and applications
Gerard Borg,J. H. Harris,Nicholas G. Martin,David Thorncraft,R Milliken,D Miljak,Brian Kwan,T Ng,J Kircher +8 more
TL;DR: In this article, the surface wave driven plasma column can replace metal as the guiding medium in radio frequency antennas, which offers the possibility of low radar detectability and negligible mutual coupling when de-energized.
Journal ArticleDOI
Application of plasma columns to radiofrequency antennas
TL;DR: In this paper, it is demonstrated that the current distribution along the antenna can be controlled by the plasma density, and that plasma columns can be used instead of metal elements in communications antennas.
