A double-shell-target implosion was studied with the GEKKO IV glass-laser system. The inner-shell trajectory, recorded for the first time by a newly developed two-frame x-ray shadowgraphy technique, was analyzed by a self-similar flow model, implying more than 20% outer-inner kinetic-energy conversion. The trajectory also agreed with a one-dimensional code result including a vacuum insulation effect. A two-dimensional particle-in-cell simulation analyzed the illumination nonuniformity printed on the inner shell.
