March 2017 DOE Report

In-Situ Measurement of Direct-Drive Target Illumination Uniformity

Experiments are underway to infer the on-target illumination uniformity of the 60-beam OMEGA laser in these experiments. Variations in the x-ray emission from the surface of a spherical target are used to infer variation of the UV illumination. The experiments are performed with Au-coated CH spheres with diameters of 865 µm, mounted on stalks identical to those used on cryogenic target experiments (17-µm-diam SiC fibers), and are diagnosed with an array of 11 digitally recorded x-ray pinhole camera images.

The TIM-3 image corrected for limb-brightening is shown here.
