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…
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…
Quasilinear diffusion coefficients in a finite Larmor radius expansion for ion cyclotron heated plasmas
Jungpyo Lee, John Wright, Nicola Bertelli +4
In this paper, a reduced model of quasilinear diffusion by a small Larmor radius approximation is derived to couple the Maxwell's equations and the Fokker-Planck equation self-cons…
Alpha Channeling with High-field Launch of Lower Hybrid Waves
Ian E. Ochs, Nicola Bertelli, Nathaniel J. Fisch
Although lower hybrid waves are effective at driving currents in present-day tokamaks, they are expected to interact strongly with high-energy particles in extrapolating to reactor…
Coupling of alpha-channeling to parallel wavenumber upshift in lower hybrid current drive
Ian E. Ochs, Nicola Bertelli, Nathaniel J. Fisch
Although lower hybrid waves have been shown to be effective in driving plasma current in present-day tokamaks, they are predicted to strongly interact with the energetic alpha part…
