Magnetic Barriers and their q95 dependence at DIII-D
F. A. Volpe, J. Kessler, H. Ali +2
It is well known that externally generated resonant magnetic perturbations (RMPs) can form islands in the plasma edge. In turn, large overlapping islands generate stochastic fields…
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…
Scaling of spontaneous rotation with temperature and plasma current in tokamaks
F. I. Parra, M. F. F. Nave, A. A. Schekochihin +6
Using theoretical arguments, a simple scaling law for the size of the intrinsic rotation observed in tokamaks in the absence of momentum injection is found: the velocity generated…
An Enhanced Nonlinear Critical Gradient for Electron Turbulent Transport due to Reversed Magnetic Shear
J. L. Peterson, G. W. Hammett, D. R. Mikkelsen +5
The first nonlinear gyrokinetic simulations of electron internal transport barriers (e-ITBs) in the National Spherical Torus Experiment show that reversed magnetic shear can suppre…
Fluid Dynamics of Stellar Jets in Real Time: Third Epoch HST Images of HH 1, HH 34, and HH 47
P. Hartigan, A. Frank, J. M. Foster +6
We present new, third-epoch HST H-alpha and [S II] images of three HH jets (HH 1 and 2, HH 34, and HH 47) and compare these images with those from the previous epochs. The high-spa…
