Computerized Tomography of a Translated Field-Reversed Configuration Plasma in the Fix Device

A computerized tomography (CT) system for the translation experiment of field-reversed configuration (FRC) is completed on the FIX device. This system is composed of three detector arrays which are sensitive to the near infrared radiation. To avoid light reflection at the vacuum wall, a black anodized aluminum panel is installed just inside of the metal chamber. Two dimensional distribution of the light emissivity of a translated FRC plasma is reconstructed using the Fourier-Bessel expansion technique.
