Abstract
The radiation field in a hohlraum (4 mm diameterx4 mm length) with a simila r to 10 TW x-ray input has been simultaneously measured by two independent techniques. An active shock breakout measurement of radiation-driven shock velocity in aluminum indicates a peak radiation field with incident flux eq uivalent to a Planckian distribution with a temperature of 147 +/-3 eV. In the same experiment, a time- and spatially resolved measurement of x-ray re -emission from the gold hohlraum wall indicates re-emission flux equivalent to a Planckian brightness temperature of 145 +/-5 eV.
