Flash x radiography can provide important information about high‐density, high‐opacity plasmas. Experiments at KMS investigated the characteristics of point x‐ray sources produced when coated fibers, wires, and mounted particles were irradiated with high intensity (I>1016W/cm2) green laser light. The target materials Bi, CsI, Au, and Ag were evaluated in the areas of (1) the spatial and temporal resolutions that can be achieved, (2) the effect of source size and laser pulse duration on x‐ray signal strength, and (3) the practical considerations associated with using the technique to actually obtain radiographs of accelerated polyvinyl alcohol shells.
