A supersonic gas-jet target platform has been activated on the OMEGA Laser System. An analytic model for gas dynamics in a supersonic nozzle was used to predict gas-plume parameters and to design nozzles for use in laser-plasma experiments. The gas-jet system was analyzed with a Mach-Zehnder interferometer to study neutral density and with Thomson scattering to study plasma parameters on the OMEGA Laser System. These initial measurements demonstrate the capabilities of the OMEGA gas jet as a platform for future laser-plasma interaction science.

Transition metal nitrides have extensive applications, including magnetic storage devices, hardware resistance coatings, and low-temperature fuel cells. This study investigated the structural, electrical, and mechanical properties of thin zirconium nitride (ZrN) films by examining the effects of laser irradiation times. Thin ZrN films were deposited on glass substrates using pulsed DC magnetron sputtering and irradiated with a diode laser for 6 and 10 min.

A laser particle analyzer (Malvern Instruments Analysis) was used to determine that the particle sizes of the raw SSP, SP, and FGD materials were concentrated between 5 and 40 μm, indicating that they were fine-grained minerals. SSP and SP are highly active alkaline substances.

This study investigates the fabrication of phase change material-poly(butylene adipate--terephthalate) (PCM-PBAT) composites through melt blending techniques, focusing on the impact of isophorone diisocyanate (IPDI) treatment on carbon nanotubes (CNTs) and (3-aminopropyl)triethoxysilane (APTES) treatment on aluminum nitride (AlN) particles. Analysis of mechanical properties highlights an enhancement in tensile strength with APTES-treated AlN particles, while dynamic mechanical analysis (DMA) reveals an increase in stiffness. Laser flash analysis (LFA) investigation demonstrates a significant increase, up to 325%, in thermal conductivity compared to PCM-PBAT composites without filler.

Diffusion-dominated mix in inertial confinement fusion (ICF) is characterized where the majority of the mix occurs in the immediate fuel-shell interface while hydrodynamic-dominated mix pulls shell material from farther away into the central fuel. A thin (150 nm) separated reactants ICF mix platform is highly sensitive to the amount of mix from the first micron of shell-fuel interface. This fine-spatial resolution platform has revealed that material mix in moderate convergence (CR∼12) ICF implosions is dominated by a diffusion mechanism.

Proton radiography is a central diagnostic technique for measuring electromagnetic (EM) fields in high-energy-density, laser-produced plasmas. In this technique, protons traverse the plasma where they accumulate small EM deflections which lead to variations in the proton fluence pattern on a detector. Path-integrated EM fields can then be extracted from the fluence image through an inversion process.
