Abstract

Spectra obtained from the TFR-600 tokamak are analyzed between 80 and 200 Å. New lines are identified in the chromium and nickel spectrum and wavelengths of several iron lines previously identified only in solar-flare spectra are compared with those obtained in a laboratory plasma spectrum. A brief comparison of tokamak plasma spectra with solar-flare and laser-produced plasma spectra is also included.
