    Description / Table of Contents: Zusammenfassung Der Aufsatz behandelt das Aufschmelzen einer horizontalen Eisschicht von oben mittels einer wäßrigen Lösung niedrigen Gefrierpunktes. Die in diesem Experiment verwendeten Lösungen sind Natriumchlorid NaCl, Kalziumchlorid CaCl2, Magnesiumchlorid MgCl2 und Harnsäure CO(NH2)2. Die Oberfläche der wäßrigen Lösung und der Schmelze wurde mit einer Infrarotlampe beheizt, deren Temperatur bei 8–40
    Notes: Abstract This paper is concerned with the melting of horizontal ice layer from above by aqua-solvent with low solidification point. The solute used in this experiment are Sodium chloride NaCl, Calcium chloride CaCl2, Magnesium chloride MgCl2, and Urea CO(NH2)2- The upper surface of aqua-solvent melt layer is heated by an infrared lamp, whose temperature is in the range of about 8

    Notes: Stimulated Raman scattering (SRS) in cannonball targets was experimentally investigated. Above the observed threshold laser intensity, the energy conversion to superhot electrons (E=100–800 keV) shows an increase of five orders of magnitude without saturation. Major differences in observing SRS from cannonball targets and directly driven targets lie in the background electron temperature and the electron plasma density where SRS occurs. A simple model calculation is presented and is compared with the data to infer coronal temperatures. The electron density ranges from 5×1019 to 3×1020 cm−3 and the coronal temperature is 0.2 keV for cannonball targets including cavity targets, while the density ranges from 3×1020 to 6×1020 cm−3 and the temperature is 1 keV for the directly driven target. The generation efficiency of SRS light is strongly correlated with superhot electron generation.
