For ion energy loss measurements in plasmas with near solid densities, an indirect laser heating scheme for carbon foils has been developed at GSI Helmholtzzentrum für Schwerionenforschung GmbH (Darmstadt, Germany). To achieve an electron density of 10^22 cm^3 and an electron temperature of 10–30 eV, two carbon foils with an areal density of 100 μg/cm^2 heated in a double-hohlraum configuration have been chosen. In this paper we present the results of temperature measurements of both primary and secondary hohlraums for two different hohlraum designs. They were heated by the PHELIX laser with a wavelength of 527 nm and an energy of 150 J in 1.5 ns. For this purpose the temperature has been investigated by an x-ray streak camera with a transmission grating as the dispersive element.
