M. Lebedev et al., SUPERSONIC HEAT-WAVE IN LOW-DENSITY FOAMS GENERATED BY SOFT X-RADIATION FROM A Z-PINCH PLASMA, Physics letters. A, 240(1-2), 1998, pp. 73-76
An intense soft X-ray pulse of radiation approximate to 1 TW/cm(2) gen
erates in low (less than 50 mg/cm(3)) density foam nonlinear radiative
heat waves, which propagate with a velocity several times higher than
the sound velocity. A foam density of 5 mg/cm(3) was achieved in expe
riments. The experimental measurements are compared with the one-dimen
sional computer simulations results. (C) 1998 Published by Elsevier Sc
