Abstract
A time- and space-resolving vacuum ultraviolet (VUV) spcctrograph has been developed and is applied as an impurity diagnostic in the tandem mirror GAMMA 10. The VUV spectrograph enables us to analyze the spatial distributions of plasma radiation in the wavelength range from 15 nm to 105 nm. Calibration of the VUV spcctrograph was carried out in order to determine the sensitivity of the spectrograph as a function of wavelength. We also established a method of analyzing the emissivity profiles of each spectral source in a visual manner from spatially resolved VUV spcctrophotograph in the GAMMA 10. KEYWORDS: vacuum ultraviolet spectrograph, plasma diagnostics, GAMMA 10
