Spectral lines of carbon, nitrogen, oxygen, and silicon have been measured and identified on spectrograms obtained from a large theta-pinch plasma device. The first spectrogram, a time-integrated exposure at grazing incidence, covered the region from 15 to 210A. Wavelengths of approximately 350 spectral lines were determined with a maximum error of 0.008A between 15A and 130A and with a maximum error of 0.015A for the remainder of the spectrogram due to a lack of suitable standard lines. The region from 350A to 1800A was photographed in two sections 350A to 1050A, and 950A to 1800A. Approximately 100 lines were measured and identified. The wavelengths for the grazing incidence spectrogram were calculated by means of a computer program, written in Fortran IV, which is given together with a detailed explanation of its use. Author
