National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

X-ray Yield Scaling Studies Performed on the Omega Laser.

Abstract	We have performed experiments with planar targets on the OMEGA laser facility at the University of Rochester. These experiments investigated the scaling of x-ray yield and conversion efficiency with the laser energy and focusing properties for several different target materials. The experiments were also designed to investigate teh feasibility of high-energy backlighters under typical irradiance geometries. The scaling of Fe emission near 6.7 keV was investigated by varying laser irradiance from 10(14) to 10(16) W/Cm(2). In addition, the scaling of x-ray yield with emitted x-ray energy was studied at fixed laser irradiance near(16) W/cm(2) for Fe, Zn, and Ge. The time-integrated spectra as well as filtered x-ray film gave relative x-ray yields.
