Hohlraums measuring 6 mm in diameter by 7 mm height have been heated by x r
ays from a Z pinch. Over the measured x-ray input powers P of 0.7 to lj TW,
the hohlraum radiation temperature T increases from similar to 55 to simil
ar to 130 eV, and is in agreement with the Planckian relation T similar to
P-1/4. The results suggest that indirect-drive inertial-confinement-fusion
experiments involving National Ignition Facility relevant pulse shapes and
<2 mm diameter capsules can be studied using this arrangement.
