E. Dattolo et al., Status of our understanding and modeling of x-ray coupling efficiency in laser heated hohlraums, PHYS PLASMA, 8(1), 2001, pp. 260-265
Recent changes in the manner of performing hohlraum drive experiments have
significantly advanced the ability to diagnose, understand and control the
x-radiation flux (or drive) inside a laser heated hohlraum. Comparison of m
odeling and data from a very broad range of hohlraum experiments indicates
that radiation hydrodynamics simulation codes reproduce measurements of tim
e dependent x-radiation flux to about +/-10%. This, in turn,indicates that
x-ray production and capsule coupling in ignition hohlraums will be very cl
ose to expectations. This article discusses the changes to experimental pro
cedures and the broad variety of measurements and tests leading to these fi
ndings. (C) 2001 American Institute of Physics. [DOI: 10.1063/1.1324659].
