Non-resonant destabilization of (1/1) internal kink mode by suprathermal electron pressure

Journal Article Delgado-Aparicio, L. ; Sugiyama, L. ; Shiraiwa, S. ; ... - Physics of Plasmas

Here in this paper, new experimental observations are reported on the structure and dynamics of short-lived periodic (1,1) “fishbone”-like oscillations that appear during radio frequency heating and current-drive experiments in tokamak plasmas. For the first time, measurements can directly relate changes in the high energy electrons to the mode onset, saturation, and damping. In the relatively high collisionality of Alcator C-Mod with lower hybrid current drive, the instability appears to be destabilized by the non-resonant suprathermal electron pressure—rather than by wave-particle resonance, rotates toroidally with the plasma and grows independently of the (1,1) sawtooth crash driven by the thermal plasmamore » pressure.« less

Fast-ion transport in qmin>2, high- β steady-state scenarios on DIII-D

Journal Article Holcomb, C. T. ; Heidbrink, W. W. ; Ferron, J. R. ; ... - Physics of Plasmas

The results from experiments on DIII-D [J. L. Luxon, Fusion Sci. Technol. 48, 828 (2005)] aimed at developing high β steady-state operating scenarios with high-qminqmin confirm that fast-ion transport is a critical issue for advanced tokamak development using neutral beam injection current drive. In DIII-D, greater than 11 MW of neutral beam heating power is applied with the intent of maximizing β _N and the noninductive current drive. However, in scenarios with q _min>2 that target the typical range of q ₉₅= 5–7 used in next-step steady-state reactor models, Alfvén eigenmodes cause greater fast-ion transport than classical models predict.

High density LHRF experiments in Alcator C-Mod and implications for reactor scale devices

Journal Article Baek, S. G. ; Parker, R. R. ; Bonoli, P. T. ; ... - Nuclear Fusion

Parametric decay instabilities (PDI) appear to be an ubiquitous feature of lower hybrid current drive (LHCD) experiments at high density. In density ramp experiments in Alcator C-Mod and other machines the onset of PDI activity has been well correlated with a decrease in current drive efficiency and production of fast electron bremsstrahlung. However whether PDI is the primary cause of the 'density limit', and if so by exactly what mechanism (beyond the obvious one of pump depletion) has not been clearly established. In order to further understand the connection, the frequency spectrum of PDI activity occurring during Alcator C-Mod LHCDmore »« less

20 years of research on the Alcator C-Mod tokamak

Journal Article Greenwald, M. ; Bader, A. ; Baek, S. ; ... - Physics of Plasmas

The object of this review is to summarize the achievements of research on the Alcator C-Mod tokamak [Hutchinson et al., Phys. Plasmas 1, 1511 (1994) and Marmar, Fusion Sci. Technol. 51, 261 (2007)] and to place that research in the context of the quest for practical fusion energy. C-Mod is a compact, high-field tokamak, whose unique design and operating parameters have produced a wealth of new and important results since it began operation in 1993, contributing data that extends tests of critical physical models into new parameter ranges and into new regimes.

Modelling of the EAST lower-hybrid current drive experiment using GENRAY/CQL3D and TORLH/CQL3D

Journal Article Yang, C. ; Bonoli, P. T. ; Wright, J. C. ; ... - Plasma Physics and Controlled Fusion

The coupled GENRAY-CQL3D code has been used to do systematic ray-tracing and Fokker–Planck analysis for EAST Lower Hybrid wave Current Drive (LHCD) experiments. Despite being in the weak absorption regime, the experimental level of LH current drive is successfully simulated, by taking into account the variations in the parallel wavenumber due to the toroidal effect. The effect of radial transport of the fast LH electrons in EAST has also been studied, which shows that a modest amount of radial transport diffusion can redistribute the fast LH current significantly. Taking advantage of the new capability in GENRAY, the actual Scrape Offmore »« less
