Description
Summary:The results of a survey of X-ray spectra from elements across the periodic system are reported. The work has two motivations: plasma diagnostics including tests of laser-plasma models, and characterization of the laser plasma as a fast, intense source of soft X rays with several applications. Several characteristics of the X-ray emission from plasmas produced at the focus of a high-power laser were measured. X-ray spectra in the 1 to 2-keV region show that the plasmas contain highly stripped atoms (10 to 12 electrons missing from Al, 20 to 22 from Zn, and 36 to 38 from Gd). The laser-plasma X-ray source can emit about 0.1 J of X rays above 1 keV in 1 nsec from a volume about 100 micrometers in diameter.
