High-resolution spectra from the Princeton Large Torus plasma have been recorded by a 2-m Schwob-Fraenkel soft-x-ray multichannel spectrometer. Spectra covering a wavelength range of approximately 50 A were recorded every 50 msec, and the spectra were normalized and added together to produce composite spectra covering the region 80--340 A. Several well-known reference lines were used to establish an absolute wavelength scale, and transition wavelengths were measured to an accuracy of approximately 0.02 A. By subtracting spectra recorded at various times throughout the discharge, transitions from ions formed in the cooler and hotter plasmas were easily distinguished, and blends between hot and cold transitions were resolved. Wavelengths of transitions in C, O, Ti, Cr, Mn, Fe, and Ni have been measured.
