The
lasnex
computer code [Comments Plasma Phys. Controlled Fusion 2, 51
(1975)] was used in the design and analysis of an
experimental study of laser-driven plasma blowoff from gold
disks. In the study, several temporal profiles of
0.53 mm laser illumination were used, including
square pulses, picket pulse trains, and pulses with
graduated leading edges. Preliminary modeling suggested
diagnostic techniques [time- and space-resolved
imaging of M-band x-ray emission and time- and
space-averaged measurements of high-energy (3.5–20 keV) x-ray
spectra] that complemented diagnostics already used
in such experiments (four-frame holographic imaging to
determine the electron-density profile in the underdense
corona plasma). In this article, the
lasnex results are analyzed and are
compared
with the measured plasma electron-density profiles and with
time- and space-averaged measurements of the corona
temperature. The simulation tracks the observed
electron-density profiles fairly well during the early portions
of the laser drive, during which the spatial profiles
are approximately self-similar, but overestimates the
electron density in the later, steady-state segment
of the profile. For the corona electron temperature, simulation
and experiment agree to within the experimental accuracy
of ±20%. Physics of Fluids B: Plasma Physics is copyrighted by

An analytic
solution to the problem of nonlocal heat transport in
plasmas by electrons whose range is not short compared to
the temperature scale length is presented. The formalism extends
the results of Albritton et al. [Phys. Rev. Lett. 57,
1887
(1986)] to an arbitrary ionization state Z. This simple
transport scheme is checked against recent
experiments in the AURORA device [Phys. Fluids B 1,
741 (1989)]. The agreement, both for the measured
cold electron temperature profile and the plasma potential,
is very good and comparable to the result of full
kinetic calculations. Physics of Fluids B: Plasma Physics
