Paper Abstract

Extreme ultraviolet (XUV) emission from hot, dense plasmas produced by the OMEGA laser at the Laboratory for Laser Energetics has been studied using a 3 meter grazing incidence spectrograph. Targets were composed of elements with atomic numbers in the range Z=14-92. These targets were irradiated by the 24 beams of the OMEGA laser focused to intensities between 10 14 wicm2 and 5 x 1016 W/cm2. High-resolution spectra were recorded in the wavelength region 6 I to 370 A, and spectral lines have been identified from ions in the isoelectronic sequences H I through Zn I. Based on these spectra, we have investigated relativistic and quantum electrodynamic (QED) effects in highly-charged ions, XUV continuum emission from high-Z plasmas, XUV spectroscopy of interest for x-ray laser research, and electron temperature and density in the coronal plasma.
