A system for obtaining spectra using a CCD linear array has been elaborated for a unique VUV spectrometer based on a spherical diffraction grating with a radius of 6.65 m. A HAMAMATSU S11156-2048-02 linear array was used. It was installed tangentially to the Rowland circle with the possibility of mechanical displacement for spectral scanning. Spectrograms were obtained in the wavelength range 2130-2270 Angstrem. A method for matching the recorded spectral segments to obtain an overview spectrogram is described. A technique for analyzing the wings of spectral lines in order to extract the Lorentzian contribution is proposed. Keywords: electrical discharges, multicharged ions, CCD, UV-spectroscopy.
