Multiple-view spectrally resolved x-ray imaging observations of polar-direct-drive implosions on OMEGA
R. C. Mancini, H. M. Johns, T. Joshi +13
We present spatially, temporally, and spectrally resolved narrow- and broad-band x-ray images of polar-direct-drive (PDD) implosions on OMEGA. These self-emission images were obtai…
Gyrokinetic studies of the effect of beta on drift-wave stability in NCSX
J. A. Baumgaertel, G. W. Hammett, D. R. Mikkelsen +2
The gyrokinetic turbulence code GS2 was used to investigate the effects of plasma beta on linear, collisionless ion temperature gradient (ITG) modes and trapped electron modes (TEM…
Comparing linear ion-temperature-gradient-driven mode stability of the National Compact Stellarator Experiment and a shaped tokamak
J. A. Baumgaertel, G. W. Hammett, D. R. Mikkelsen
One metric for comparing confinement properties of different magnetic fusion energy configurations is the linear critical gradient of drift wave modes. The critical gradient scale…
Simulating Gyrokinetic Microinstabilities in Stellarator Geometry with GS2
J. A. Baumgaertel, E. A. Belli, W. Dorland +6
The nonlinear gyrokinetic code GS2 has been extended to treat non-axisymmetric stellarator geometry. Electromagnetic perturbations and multiple trapped particle regions are allowed…
