Measurement of shifts and widths of spectral lines in a laser-produced plasma

Thesis/Dissertation ·
OSTI ID:5002966
The shift and broadening of spectral lines in a dense plasma is investigated using a laser-produced plasma. The plasma is produced by the Glass Development Laser at the Laboratory for Laser Energetics at the University of Rochester. The near-ultraviolet (3513 Angstroms) laser beam is focused onto targets of glass and plastic, producing spectra of C VI, O VIII, and F IX. The spectra are observed with a 3-meter grazing-incidence spectrograph. Wavelength calibration is obtained by spectra from heavy metal targets. The theoretical basis for shifts of spectral lines by plasma polarization effects is discussed, and theoretical estimates are given for Lyman series lines of the above elements.
