Notes:
We are developing a backlighter in the 4–10 keV energy range using K-shell spectra from elements with Z≤30 and the L-shell spectra from elements with Z≥58. Using one beam of the Nova laser yielded about 3.0 kJ of 0.53 μm wavelengths light in a 1.0 ns square pulse which was focused to a spot of less than 100 μm in diameter on 12.5 and 25.0-μm-thick foil targets. Our initial results include time-resolved spectra from slab (2 mm×2 mm) and disk (100 μm diameter) targets of Ce (Z=58), Zn (Z=30), and Ti (Z=22). The Zn and Ti exhibit strong emission from the cold Kα line and satellite states, while the Ce spectra show prominent L-band structure. By exploring the differences between disks matched to the beam focus and extended slabs we hope to obtain information on plasma cooling mechanisms.
