Rigid Rotor Profiles for a Field-Reversed Configuration

POSTER

Abstract

The radial profiles for a Field-Reversed Configuration (FRC) are measured and compared to predictions of the Rigid Rotor (RR) Model, a time-independent, analytic description for the FRC equilibrium.$\footnote{N. Rostoker and A. Qerushi, Phys Plasmas 9(7), p.3057(2002).}$ Injectors mounted on both ends of the confinement section create a plasma pre-fill in the vacuum chamber. A coaxial-coil system, two coils, one inside the plasma and another outside, accelerates the plasma producing a FRC. Diagnostics measure the plasma density, magnetic-field, and electric-field profiles, n(r), Bz(r), and Er(r). The measured profiles agree with the 1-D RR model predictions, supporting the validity of this model as a basis for describing this specific start-up configuration for the FRC.
