High-performance diagnostic techniques have been developed for better
understanding of the physics relevant to ignition. Newly developed X-r
ay imaging of 10 ps resolution, multiple-imaging X-ray streak camera (
MIXS), has provided data of hot spark heating for the first time. Time
- and space-resolved spectroscopy has also been developed to obtain th
e temperature and density distribution of the compressed fuel. Fast ne
utron detectors for burn history measurements and neutron time-of-flig
ht spectrometers for fuel areal density and ion-temperature measuremen
ts have been developed. The data supports our understanding of implosi
on kinematics and mixing. (C) 1997 Elsevier Science S.A.
