Hydrodynamic and radiation properties of low-density polymer aerogels heated by x-rays,which were generated due to laser interaction with a gold hohlraum, have been investigated experimentally and numerically.In experiments carried out at the PALS laser facility in Prague, the parameters of the hohlraum based soft x-ray source and the fraction of x-ray energy absorbed by foam layers have been measured.The results of these experiments and numerical simulations show that the x-ray heat process occurs via propagation of supersonic radiation driven heat waves.The measured heat wave velocity of 10(7) cm s(-1) allows one to estimate Workplace Institute of Plasma Physics Contact Vladimíra Kebza, kebza@ipp.cas.cz, Tel.: 266 052 975 Year of Publishing 2016
