The dynamics of plastic foils of different thicknesses which were irradiated with intense, approximately Planckian soft-x-ray pulses, have been investigated using a high magnification (80×), time-resolving extreme ultraviolet (95 or 205 eV) imaging technique for the first time. The experimental results are discussed and compared with hydrocode simulations.
