Abstract
Inertial confinement fusion (ICF) is one of the promising approaches how to get a new resource of energy. In order to model ICF implosions reliably, the measurements of the mass ablation rates are needed. Such a measurement was performed at PALS; using the Ne-like Zn X-ray laser (XRL) as a probe beam and the Double Lloyd’s mirror interferometer as the main diagnostic. The Parylene N foil (200nm and 350nm) was heated by 250-ps pulse of 3ω iodine laser with nominal energy of 1J. The size of the focal spot was ~300μm then the maximum resulting intensity was ~1012W/cm2. The plasma probed by XRL was imaged by Mo:Si spherical mirror to CCD detector with magnification 8. The expected phase shift for the chosen thicknesses, which corresponds to reasonable fringe visibility, was from π to 2π. The recorded interferograms were taken for different time delays between the heating pulse and the probe.
