X-ray reemission from CH foils heated by laser-generated intense thermal radiation.

X-ray emission and burn through of radiatively heated plastic foils have been investigated in a gold cavity heated by eight beams of the Gekko XII laser up to a radiation temperature of 140 eV. We measured the temporally resolved reemission spectra of carbon. The time and frequency integrated reemission was 23% of the gold reemission. The measurements are in good agreement with numerical simulations.
