Measured reduction in Alfvén wave energy propagating through longitudinal gradients scaled to match solar coronal holes
Sayak Bose, Troy Carter, Michael Hahn +3
We have explored the effectiveness of a longitudinal gradient in Alfvén speed in reducing the energy of propagating Alfvén waves under conditions scaled to match solar coronal hole…
Electron Density Measurement with Hairpin Resonator in Low Pressure Plasma
Xingchen Fan, Patrick Pribyl, Troy Carter
Hairpin probes measure electron density in plasmas where other techniques are unsuitable. Previous hairpins were constructed as a quarter-wave resonant structure typically made fro…
Gyrokinetic GENE simulations of DIII-D near-edge L-mode plasmas
T. F. Neiser, F. Jenko, T. A. Carter +7
We present gyrokinetic simulations with the GENE code addressing the near-edge region of an L-mode plasma in the DIII-D tokamak. At radial position , simulations with the i…
Laboratory observation of a nonlinear interaction between shear Alfvén waves
T. A. Carter, B. Brugman, P. Pribyl +1
An experimental investigation of nonlinear interactions between shear Alfvén waves in a laboratory plasma is presented. Two Alfvén waves, generated by a resonant cavity, are observ…
Intermittent turbulence and turbulent structures in a linear magnetized plasma
T. A. Carter
Strongly intermittent turbulence is observed in the shadow of a limiter in the Large Plasma Device (LAPD) at UCLA [W. Gekelman, H. Pfister, Z. Lucky, J. Bamber, D. Leneman, and J.…
