FRC edge physics using NIMROD
November 2012 | A. Necas | APS-DPP | Poster
We have studied issues related to edge physics of the HPF regime FRC [1] ” using the NIMROD extended MHD code [2].
Interaction of Fast Ions with Global Plasma Modes in the C-2 Field Reversed Configuration Experiment
November 2012 | A. Smirnov | APS-DPP | Poster
A high-confinement operating regime [1] with plasma lifetimes significantly exceeding past empirical scaling laws was recently obtained by combining plasma gun edge biasing and tangential Neutral Beam Injection (NBI) in the C-2 field-reversed configuration (FRC) experiment [2, 3].
Simulations And Observations Of Radiation In the Electron Cyclotron Frequency Range On the C-2 Device
November 2012 | E. Trask | APS-DPP | Poster
Several different antennas have recently been fielded on the TAE Technologies C-2 [1] experimental system to measure radiation emission in the range of 1-60 GHz, where the fundamental electron cyclotron frequency is approximately 2.5 GHz at the edge of the field-reversed configuration (FRC).
Monte Carlo Simulation of Neutral Beam Injection in C-2
September 2012 | S. Dettrick | US-Japan CT Workshop | Presentation
Without magnetic perturbations, NBI energy confinement time is ~500ms. Most NBI energy goes on heating electrons. Supports the interpretation of HPF results.
NIMROD Simulations of the Stabilization of the FRC Tilt Instability with Energetic Ion Beams
September 2012 | R. Milroy | US-Japan CT Workshop | Presentation
We find beam stability of the tilt mode, in agreement with Barnes & Milroy, when similar beam and plasma parameters are applied.
Plasma Transport in Field Reversal Configuration
November 2011 | S. Gupta | APS-DPP | Poster
A Quasi-1D (Q1D) transport code is developed at Tri Alpha for predicting and interpreting the macroscopic time evolution of FRC plasmas.
