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

[摘要] 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.
