چکیده

This paper discusses high-energy-density laboratory astrophysics experiments exploring the RayleighTaylor instability under conditions similar to the blast wave driven, outermost layer in a core-collapse supernova. The planar blast wave is created in an experimental target using the Omega laser. The blast wave crosses an unstable interface with a seed perturbation machined onto it. The perturbation consists of a 3D “egg crate” pattern and, in some cases, an additional longer wavelength mode is added to this 3D, single-mode pattern. The main diagnostic of this experiment is x-ray radiography. This paper explores an image processing technique to improve the identification and characterization of structure in the radiographic data.

Nonlinear mixing behavior of the three-dimensional Rayleigh–Taylor instability at a decelerating interface

Results are reported from the first experiments to explore the evolution of the Rayleigh–Taylor RT instability from intentionally three-dimensional 3D initial conditions at an embedded, decelerating interface in a high-Reynolds-number flow. The experiments used 5 kJ of laser energy to produce a blast wave in polyimide and/or brominated plastic having an initial pressure of 50 Mbars. This blast ...

Assessing Mix Layer Amplitude in 3D Decelerating Interface Experiments

We present data from recent high-energy-density laboratory experiments designed to explore the Rayleigh– Taylor instability under conditions relevant to supernovae. The Omega laser is used to create a blast wave structure that is similar to that of the explosion phase of a core-collapse supernova. An unstable interface is shocked and then decelerated by the planar blast wave, producing Rayleigh...

Rayleigh–Taylor growth at decelerating interfaces

The Rayleigh–Taylor ~RT! instability is important in a number of research contexts. For the design or analysis of experiments and observations, it is often useful to know the growth exponent of an interface, even when the growth is strongly nonlinear. The growth exponent is defined here as the number of linear e-foldings by which initial perturbations at the interface would be amplified, if the...

Ultra-Fast Image Reconstruction of Tomosynthesis Mammography Using GPU

Digital Breast Tomosynthesis (DBT) is a technology that creates three dimensional (3D) images of breast tissue. Tomosynthesis mammography detects lesions that are not detectable with other imaging systems. If image reconstruction time is in the order of seconds, we can use Tomosynthesis systems to perform Tomosynthesis-guided Interventional procedures. This research has been designed to study u...

UWFDM-1172 Experiments on the Richtmyer-Meshkov Instability II: Nonlinear Evolution of a Shocked Membraneless Single-Mode Sinusoidal Interface

An experimental investigation of the shock-induced interfacial instability (RichtmyerMeshkov instability) is undertaken in an effort to study temporal evolution of interfacial perturbations in the nonlinear regime. The experiments are performed in a vertical shock tube with a square cross-section. A membraneless interface is prepared by retracting a sinusoidally shaped metal plate initially sep...
