A measurement system for the investigation of the translation of the field reversed configuration (FRC) plasma using computer tomography (CT) data at two different cross-sections was established. Two sets of CT devices were installed at the upstream and downstream sides of the confinement chamber of the FIX machine. Each CT device was composed of three arrays of detectors sensitive to the near-infrared radiation. The Fourier-Bessel expansion technique was employed to reconstruct the two-dimensional distributions of the light emissivity of the FRC plasma. After the completion of the translation, the intensity of emission decreased significantly, probably because the density and the temperature of the plasma were decreased due to the plasma expansion induced by the translation.
