Internal Magnetic Field Measurement on C-2 Field-Reversed Configuration Plasmas

May 2012 | H. Gota | HTPD | Poster

A reversed-field structure of the translated CTs and final merged FRC state have been directly verified by probing the internal magnetic field structure using a multi-channel magnetic probe array near the midplane of the C-2 confinement chamber.

A high temperature, stable, long-lived field-reversed configuration (FRC) plasma state has been produced in the C-2 device by dynamically colliding and merging two oppositely directed, highly supersonic compact toroids (CTs).

Two-chord interferometry using 3.39 m He–Ne laser on a flux-coil-generated FRC

October 2010 | H. Gota |Review of Scientific Instruments | Paper

A two-chord IR3.39 m He–Ne laser interferometer system was developed for a flux-coil-generated field-reversed configuration to estimate the electron density and the total temperature of the field-reversed configuration FRC plasma.
