November 2023 | S. Nicks | APS DPP 2023 | Poster
Fluid-derived critical lengths2 show qualitative agreement with kinetic AIC stabilization threshold.
Stabilization of the Alfven-ion cyclotron instability through short plasmas: Fully kinetic simulations in a high-beta regime
October 2023 | B. Nicks | Physics of Plasmas | Paper
The Alfven-ion cyclotron (AIC) mode is an instability that can be driven in magnetized plasmas with anisotropic pressure. Its chief deleterious effect is the driving of enhanced pitch-angle scattering of ions
Density Fluctuation Measurements in C-2W FRC Plasmas
October 2022 | E. Parke | APS-DPP 2022 | Poster
On C-2W (also called “Norman”) record-breaking, advanced beam-driven fieldreversed-configuration (FRC) plasmas are produced and sustained in steady state
Fast Ion Stabilization of the Internal Tilt Mode in C-2W
November 2021 | T. DeHaas | APS-DPP 2021 | Poster
Traditional FRCs are known to be theoretically unstable to an internal tilt mode whose threshold is characterized by the parameter S*/E.
The Tearing Mode in C-2W
November 2021 | M. Tobin | APS-DPP 2021 | Poster
We report on the observation of axisymmetric periodic deformations of the FRC in external magnetic field and internal electron density measurements in C-2W that appear consistent with the tearing mode.
