Filter-mirror transmissions for the gated soft x-ray imaging.
Gated soft x-ray images of Au targets at laser intensity at and corresponding horizontal intensity line outs.
Total and -band soft x-ray fluxes measured by the Dante spectrometer for (a) , incident laser intensity for Au (dashed lines) and cocktails (solid lines) and (b) for , incident intensity for Au (dashed), cocktails (thick solid), and U (thin solid).
Typical light backscattering spectrum from the target for laser intensity.
Total incident laser power, scattered light and the resulting laser coupling in the target at (a) and (b) at laser intensities onto the targets.
Laser power coupled onto the target, total x-ray flux measured by the Dante spectrometer and the resulting time resolved x-ray conversion efficiency for (a) laser intensity onto the target and (b) for intensity; the plot for includes time resolved conversion efficiency as calculated by LASNEX using XSN and a flux limiter of 0.15.
Dependence of calculated laser absorption and x-ray production on the flux limiter for the Au target at intensity (LASNEX 1D calculations).
Calculated absorbed laser power, generated x-ray flux, and the resulting x-ray conversion efficiency for flat top incident laser power for (a) laser intensity onto the target and for (b) intensity; incident laser power is also shown.
Measured [(a), (b)] and calculated [(c), (d)] x-ray spectra at the peak of the x-ray drive (Fig. 3) for [(a), (c)] laser intensity onto the target and [(b), (d)] for intensity.
X-ray spectra measured by the Henway spectrometer for Au and cocktails for both laser intensities.
Total (squares) and -band (, circles) x-ray conversion efficiencies averaged over the last of the laser pulse for the different high-Z materials and laser intensities; full points show experimental data and empty points are LASNEX simulations using the XSN model and a flux limiter of 0.15.
