Abstract

A computer tomography system for the axial compression experiment of field reversed configuration (FRC) plasma is completed on the FIX device. This system is composed of three arrays of detectors sensitive to the near-infrared radiation. Two-dimensional distributions of the light emissivity of FRC plasmas are reconstructed using the Fourier-Bessel expansion technique. It is found that after the axial compression, the intensity of the light emissivity of the FRC plasma increases as well as the separatrix radius increases
