Title: The effects of microstructure on propagation of laser-driven radiative heat waves in under-dense high-Z plasma

Abstract

This work was motivated by previous findings that the measured laser-driven heat front propagation velocity in under-dense TiO₂/SiO₂ foams is slower than the simulated one [Pérez et al., Phys. Plasmas 21, 023102 (2014)]. In attempting to test the hypothesis that these differences result from effects of the foam microstructure, we designed and conducted an experiment on the GEKKO laser using an x-ray streak camera to compare the heat front propagation velocity in “equivalent” gas and foam targets, that is, targets that have the same initial density, atomic weight, and average ionization state. In this article, we first discuss the design and the results of this comparison experiment. To supplement the x-ray streak camera data, we designed and conducted an experiment on the Trident laser using a new high-resolution, time-integrated, spatially resolved crystal spectrometer to image the Ti K-shell spectrum along the laser-propagation axis in an under-dense TiO₂/SiO₂ foam cylinder. We discuss the details of the design of this experiment, and present the measured Ti K-shell spectra compared to the spectra simulated with a detailed superconfiguration non-LTE atomic model for Ti incorporated into a 2D radiation hydrodynamic code. Finally, we show that there is indeed a microstructure effect on heat frontmore »« less

Simulation studies of the interaction of laser radiation with additively manufactured foams

Journal Article Milovich, J. L. ; Jones, O. S. ; Berger, R. L. ; ... - Plasma Physics and Controlled Fusion

The interaction of laser radiation with foams of various porosities and low densities has been the subject of several numerical and experimental studies. In all cases, the modeling of low-Z under-dense foams as uniform gases of equivalent average density using standard radiation-hydrodynamics codes has resulted in heat-front velocities that are considerably faster than those observed experimentally. It has been theoretically conjectured that this difference may be attributed to the breakdown of the foam’s morphology, leading to a dynamics of filament expansion where the ion and electron energy partitions are significantly different from those calculated using the uniform gas model.

Efficient Multi-keV X-ray Sources from Ti-doped Aerogel Targets

Conference Fournier, K B ; Constantin, C ; Poco, J ; ...

We have measured the production of h{nu} {approx}> 4.5 keV x-rays from low-density Ti-doped aerogel targets at the OMEGA laser facility (University of Rochester). The targets were 2.2 mm long by 2 mm diameter beryllium cylinders filled with Ti-doped (3 atomic percent) SiO{sub 2} foam. The doped-foam density was {approx} 3 mg/cc. Forty beams of the OMEGA laser ({gamma} = 351 nm) illuminated the two cylindrical faces of the target with a total power that ranged from 7 to 14 TW. The laser interaction fully ionizes the target (n{sub e}/n{sub crit} {approx}< 0.1), and allows the laser-bleaching wave to excite,more »« less

Laser transport and backscatter in low-density SiO₂ and Ta2O₅ foams

Journal Article Mariscal, D. A. ; Jones, O. S. ; Berger, R. L. ; ... - Physics of Plasmas

Experiments using a single 527 nm wavelength beam interacting with sub- and supercritical density SiO₂ and Ta₂O₅ foams examined laser propagation and backscatter from laser–plasma instabilities such as Stimulated Brillouin Scattering (SBS). Two densities of each material were examined, and multiple diagnostics were used to characterize the propagation and backscatter. For 5 mg/cc SiO₂ (n_e/n_c = 0.375), the laser propagation distance was well approximated by treating the foam as a gas. However, for the 2 mg/cc SiO₂ foam (n_e/n_c = 0.15), the same model over-predicts the propagation distance by ~40%. Furthermore, existing analytical theories on propagation through subcritical foams weremore »« less

Laser propagation in a subcritical foam: Subgrid model

Journal Article Belyaev, M. A. ; Berger, R. L. ; Jones, O. S. ; ... - Physics of Plasmas

Here, we present a subgrid model for laser propagation in a subcritical foam. Our model describes the expansion of laser-irradiated foam elements that are below the resolution of the simulation grid and predicts the plasma conditions that result from burning down the foam. Our model can be included as a module within a larger multiphysics code, and we have implemented it within the code pF3D, which is used for simulating a laser-plasma interaction. The model predicts a reduced propagation velocity for a laser through a subcritical foam compared to simulating that foam as a homogeneous gas. This is attributed tomore »« less
