Turbulent hydrodynamic mixing induced by the Rayleigh–Taylor (RT) and Richtmyer–Meshkov (RM) instabilities occurs in settings as varied as exploding stars (supernovae), inertial confinement fusion (ICF) capsule implosions, and macroscopic flows i

Experiments conducted on the Omega laser [T. R. Boehly et al., Opt. Commun. 133, 495 (1997)] and simulations show reduced Richtmyer–Meshkov growth rates in a strongly shocked system with initial amplitudes kη0⩽0.9. The growth rate at early time

Millimeter-scale shock tubes with precision-machined submillimeter features have been developed for hydrodynamic instability experiments conducted on the Nova laser facility. We will describe two specific designs: a silica aerogel tracer disk and an

We present the first experimental measurement of the growth of a mixing region at a density interface from a high-amplitude, initially nonlinear perturbation. Thermal radiation from a gold {ital Hohlraum} irradiated by the Nova laser was used to driv

A large ion Larmor radius plasma undergoes a particularly robust form of Rayleigh–Taylor instability when sub‐Alfvenically expanding into a magnetic field. Results from an experimental study of this instability are reported and compared with theo

Time resolved x‐ray radiographic measurements at high photon energy (∼7 keV) are used to observe radiation‐driven shock propagation and interface motion in solid density plastic samples, produced by indirect drive on the Nova laser. Measurement

High‐intensity laser irradiation of hollow glass cylinders immersed in a magnetic field results in plasma expansions strongly collimated in the direction transverse to both the initial flow and the magnetic field, but jetlike in the direction paral

A multi‐element segmented concentric Faraday collector has been developed for measuring the time evolution of the beam half‐current radius (a1/2) of an intense relativistic electron beam. Each collector segment measures the total current within i

Measurements of the 3ω0/2 emission from laser‐irradiated targets at 0.53 μm were made at three angles over a wide range of laser bandwidths with and without induced spatial incoherence (ISI) echelons. The 3ω0/2 emission was found to be correlate

Laser-produced plasmas have many properties similar to, or which can be scaled to, those encountered in space, magnetospheric, ionospheric, and astrophysical situations. We describe several such experiments performed with the PHAROS III Nd-laser faci
