8–11-keV x-ray sources for imaging and absorption experiments

Abstract
We have measured the 8–11‐keV emission spectra from plasmas produced by impinging 0.53‐μm, 100‐ and 200‐ps FWHM Gaussian laser pulses on targets of different materials. The experimental spectra from W and Zn are identified by comparison with local thermodynamic equilibrium plasma emission calculations.
