Modeling feedback control of unstable separatrix location in beam-driven field-reversed configurations
March 2017 | Niko Rath | AIP Publishing | Paper
We present a linear, one-parameter model for rigid displacement of a toroidally symmetric plasma.
FRC equilibrium reconstruction by Bayesian evaluation of Monte Carlo transport simulations
October 2016 | Niko Rath | APS-DPP | Poster
Many Q2D simulations are chopped into even more independent snapshots, forming a “pool” of “states”.
Positional stability of field-reversed-configurations in the presence of resistive walls
June 2016 | Niko Rath | AIP Publishing | Paper
We show that in a field-reversed-configuration, the plasma is unstable to either transverse or axial rigid displacement, but never to both.
