Parametric Decay of Broadband Lower Hybrid Waves
S. Jin, A. K. Ram, S. G. Baek +1
We derive a nonlinear dispersion relation for the parametric decay of an arbitrary lower hybrid pump spectrum, generalizing the standard three-wave treatment to the broadband case.…
Spectral broadening from turbulence in multiscale lower hybrid current drive simulations
Bodhi Biswas, Paul Bonoli, Abhay Ram +1
The scattering of lower hybrid (LH) waves due to scrape-off layer (SOL) filaments is investigated. It is revealed that scattering can account for the LH spectral gap without any ad…
A quasi-local inhomogeneous dielectric tensor for arbitrary distribution functions
S. J. Frank, J. C. Wright, P. T. Bonoli
Treatments of plasma waves usually assume homogeneity, but the parallel gradients ubiquitous in plasmas can modify wave propagation and absorption. We derive a quasilocal inhomogen…
An Assessment Of Full-Wave Effects On Maxwellian Lower-Hybrid Wave Damping
S J Frank, J C Wright, I H Hutchinson +1
Lower-hybrid current drive (LHCD) actuators are important components of modern day fusion experiments as well as proposed fusion reactors. However, simulations of LHCD often differ…
A hybrid full-wave Markov chain approach to calculating radio-frequency wave scattering from Scrape-off Layer filaments
Bodhi Biswas, Syunichi Shiraiwa, Seung-Gyou Baek +3
The interaction of radio-frequency (RF) waves with edge turbulence modifies the incident wave-spectrum, and can significantly affect RF heating and current drive in tokamaks. Previ…
Importance of theory, computation and predictive modeling in the US magnetic fusion energy strategic plan
Fatima Ebrahimi, Gary Staebler, Paul Bonoli +5
Based on the community input at the National Academy of Sciences (NAS) Madison and Austin workshops in July and December 2017, respectively, this whitepaper was prepared and submit…
Generation of Localized Lower-Hybrid Current Drive By Temperature Perturbations
S. J. Frank, A. H. Reiman, N. J. Fisch +1
Despite high demonstrated efficiency, lower-hybrid current drive (LHCD) has not been considered localized enough for neoclassical tearing mode (NTM) stabilization in tokamaks. This…
A positive-definite form of bounce-averaged quasilinear velocity diffusion for the parallel inhomogeneity in a tokamak
Jungpyo Lee, David Smithe, John Wright +1
In this paper, the analytical form of the quasilinear diffusion coefficients is modified from the Kennel-Engelmann diffusion coefficients to guarantee the positive definiteness of…
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…
Perpendicular momentum injection by lower hybrid wave in a tokamak
Jungpyo Lee, Felix I. Parra, Ron R. Parker +1
The injection of lower hybrid waves for current drive into a tokamak affects the profile of intrinsic rotation. In this article, the momentum deposition by the lower hybrid wave on…
