Abstract

The FIREX-1 project, the goal of which is to demonstrate fuel heating up to 5 keV by fast ignition scheme, has been carried out since 2003 including construction and tuning of LFEX laser and integrated experiments. Implosion and heating experiment of Fast Ignition targets have been performed since 2009 with Gekko-XII and LFEX lasers. A deuterated polystyrene shell target was imploded with the 0.53- μm Gekko-XII, and the 1.053- μm beam of the LFEX laser was injected through a gold cone attached to the shell to generate hot electrons to heat the imploded fuel plasma. Pulse contrast ratio of the LFEX beam was significantly improved. Also a variety of plasma diagnostic instruments were developed to be compatible with harsh environment of intense hard x-rays (γ rays) and electromagnetic pulses due to the intense LFEX beam on the target. Large background signals around the DD neutron signal in time-of-flight record of neutron detector were found to consist of neutrons via (γ,n) reactions and scattered gamma rays. Enhanced neutron yield was confirmed by carefully eliminating such backgrounds. Neutron enhancement up to 3.5 × 107 was observed. Heating efficiency was estimated to be 10–20% assuming a uniform temperature rise model.

Abstract

The radiation pressure of next generation ultra-high intensity ($>10^{23}$ W/cm$^{2}$) lasers could efficiently accelerate ions to GeV energies. However, nonlinear quantum-electrodynamic effects play an important role in the interaction of these laser pulses with matter. Here we show that these effects may lead to the production of an extremely dense ($\sim10^{24}$ cm$^{-3}$) pair-plasma which absorbs the laser pulse consequently reducing the accelerated ion energy and energy conversion efficiency by up to 30-50\% \& 50-65\%, respectively. Thus we identify the regimes of laser-matter interaction where either ions are efficiently accelerated or dense pair-plasmas are produced as a guide for future experiments.

3. Rapid Embedded Wire Heating via Resistive Guiding of Laser-Generated Fast Electrons as a Hydrodynamic Driver

Abstract

Resistively guiding laser-generated fast electron beams in targets consisting of a resistive wire embedded in lower $Z$ material should allow one to rapidly heat the wire to over 100eV over a substantial distance without strongly heating the surrounding material. On the multi-ps timescale this can drive hydrodynamic motion in the surrounding material. Thus ultra-intense laser solid interactions have the potential as a controlled driver of radiation hydrodynamics in solid density material. In this paper we assess the laser and target parameters needed to achieve such rapid and controlled heating of the embedded wire.

Abstract

We report spatially and temporally resolved measurements of magnetic fields generated by petawatt laser-solid interactions with high spatial resolution, using optical polarimetry. The polarimetric measurements map the megagauss magnetic field profiles generated by the fast electron currents at the target rear. The magnetic fields at the rear of a 50 $\mu$m thick aluminum target exhibit distinct and unambiguous signatures of electron beam filamentation. These results are corroborated by hybrid simulations., Comment: 5 pages, 5 figures

Abstract

This paper describes the first experimental demonstration of the guiding of a relativistic electron beam in a solid target using two co-linear, relativistically intense, picosecond laser pulses. The first pulse creates a magnetic field which guides the higher current fast electron beam generated by the second pulse. The effects of intensity ratio, delay, total energy and intrinsic pre-pulse are examined. Thermal and K{\alpha} imaging showed reduced emission size, increased peak emission and increased total emission at delays of 4 - 6 ps, an intensity ratio of 10 : 1 (second:first) and a total energy of 186 J. In comparison to a single, high contrast shot, the inferred fast electron divergence is reduced by 2.7 times, while the fast electron current density is increased by a factor of 1.8. The enhancements are reproduced with modelling and are shown to be due to the self-generation of magnetic fields. Such a scheme could be of considerable benefit to fast ignition inertial fusion.

12. Potential for the Vishniac instability in ionizing shock waves propagating into cold gases

Author

Robinson, A. P. L. and Pasley, J.

Abstract

The Vishniac instability was posited as an instability that could affect supernova remnants in their late stage of evolution when subject to strong radiative cooling, which can drive the effective ratio of specific heats below 1.3. The potential importance of this instability to these astrophysical objects has motivated a number of laser-driven laboratory studies. However, the Vishniac instability is essentially a dynamical instability that should operate independently of whatever physical processes happen to reduce the ratio of specific heats. In this paper, we examine the possibility that ionization and molecular dissociation processes can achieve this, and we show that this is possible for a certain range of shock wave Mach numbers for ionizing/dissociating shock waves propagating into cold atomic and molecular gases.

13. Enhancing relativistic electron beam propagation through the use of graded resistivity guides

Author

Alraddadi, R. A.B., Robinson, A. P. L., Pasley, J., and Woolsey, N. C.

Abstract

We show, using three dimensional hybrid particle-in-cell simulations, that fast electron transport is improved in a resistive guide when using a linear decreasing gradient in the resistivity between the guide and substrate. We observe increased heating-at-depth along the guide and significantly reduced heating inhomogeneity. These improvements result from an increase in the width of the collimating magnetic field, improving fast electron confinement and limiting the growth of magnetic fields in the interior of the guide.

16. The effect of grading the atomic number at resistive guide element interface on magnetic collimation

Author

Alraddadi, R. A B, Robinson, A. P L, Woolsey, N. C., and Pasley, J.

Abstract

Using 3 dimensional numerical simulations, this paper shows that grading the atomic number and thus the resistivity at the interface between an embedded high atomic number guide element and a lower atomic number substrate enhances the growth of a resistive magnetic field. This can lead to a large integrated magnetic flux density, which is fundamental to confining higher energy fast electrons. This results in significant improvements in both magnetic collimation and fast-electron-temperature uniformity across the guiding. The graded interface target provides a method for resistive guiding that is tolerant to laser pointing.

Abstract

The interaction of ultrahigh power picosecond laser pulses with solid targets is of interest both for benchmarking the results of hybrid particle in cell codes and also for applications in reentrant cone guided fast ignition. We describe the construction of novel targets in which copper/titanium wires are formed into 'nail-like' objects by a process of melting and micromachining so that energy can be reliably coupled to a 24-[micro]m-diameter wire. An extreme-ultraviolet image of the interaction of the Titan laser with such a target is shown. Index Terms--Cone guided fast ignition, extreme ultraviolet imaging, laser-produced electron transport in solids, laser-solid interaction.

Abstract

A variety of targets with different dimensions and materials was irradiated using the VULCAN PW laser [C. N. Danson , Nucl. Fusion 44, S239 (2004)]. Using transverse optical shadowgraphy in conjunction with a one-dimensional radiation hydrodynamics code it was possible to determine a longitudinal temperature gradient. It was demonstrated for thick targets with a low Z substrate and a thin higher Z tracer layer at the rear that the boundary between the two materials was Rayleigh-Taylor unstable. By including a simple bubble growth model into the calculations it was possible to correct for the associated behavior with regard to temperature. The resulting temperature gradient was in good agreement with the previously published data using two different methods of determining the temperature.

26. Study of relativistic electron beam production and transport in high-intensity laser interaction with a wire target by integrated LSP modeling

Author

Wei, M. S., Solodov, A. A., Pasley, J., Stephens, R. B., Welch, D. R., and Beg, F. N.

Abstract

The results of a numerical study of high-intensity short-pulse laser interaction with wire targets are presented. Fast electron production and transport in solid density plasma is modeled using the implicit hybrid particle-in-cell code LSP [D. R. Welch et al., Phys. Plasmas 13, 063105 (2006)]. These simulations were performed with realistic target size and laser parameters and over times much longer than the laser pulse. Nonlinear interaction processes, i.e., microchanneling and density steepening, have been observed. The spectrum of the relativistic electrons produced has a reduced slope temperature compared to that predicted by ponderomotive scaling. Preformed underdense plasma has been found to bottleneck fast electrons due to the intense magnetic fields generated near the critical surface. In a thin long wire target, the overall propagation length of the fast electrons is about 160 mu m; however, surface fields guide a small fraction of electrons to longer distances. These results are in good agreement with the experiments and have demonstrated that the modeling of electron transport relevant to fast ignition can be pursued in an integrated manner.

Abstract

Laser-driven shock compression of samples precompressed to 1 GPa produces high-pressure-temperature conditions inducing two significant changes in the optical properties of water: the onset of opacity followed by enhanced reflectivity in the initially transparent water. The onset of reflectivity at infrared wavelengths can be interpreted as a semiconductorelectronic conductor transition in water, and is found at pressures above ~130 GPa for single-shocked samples precompressed to 1 GPa. Our results indicate that conductivity in the deep interior of “icy” giant planets is greater than realized previously because of an additional contribution from electrons.

Abstract

Results of experiments conducted at the Central Laser Facility (Rutherford Appleton Laboratory), illustrating the efficacy of utilizing a combination of transonic and subsonic ablation to increase the impulse delivered to an indirectly driven payload, are reported. Extreme ultraviolet imaging has been utilized to map the trajectory of the rear surface of an accelerating payload driven by a hohlraum with a peak energy-density-equivalent radiation temperature of around 130 eV. Payloads comprising an approximately 30-μm -thick solid-density plastic foil doped with chlorine, both with and without a gold flashing on the driver-facing surface, were accelerated by a combination of subsonic x-ray ablation of the rear surface of the payload and either subsonic, transonic, or supersonic ablation in a hohlraum facing low-density foam layer in intimate contact with the payload. Two different thicknesses of foam layer were incorporated in the experiment - 150 and 200 μm - in addition to a range of different foam densities from 30 to 100 mgcc. It was observed that the maximum impulse was delivered in the case where the ablation wave propagation was approximately transonic in the foam layer. In such cases the impulse delivered to the payload was significantly greater than that achieved by direct (subsonic) ablation of the payload. © 2006 American Institute of Physics.

Abstract

The optical reflectance of a strong shock front in water increases continuously with pressure above 100 GPa and saturates at similar to45% reflectance above 250 GPa. This is the first evidence of electronic conduction in high pressure water. In addition, the water Hugoniot equation of state up to 790 GPa (7.9 Mbar) is determined from shock velocity measurements made by detecting the Doppler shift of reflected light. From a fit to the reflectance data we find that an electronic mobility gap similar to2.5 eV controls thermal activation of electronic carriers at pressures in the range of 100-150 GPa. This suggests that electronic conduction contributes significantly to the total conductivity along the Neptune isentrope above 150 GPa. (C) 2004 American Institute of Physics.

Abstract

Fast electrons produced by a 10 ps, 160 J laser pulse through laser-compressed plastic cylinders are studied experimentally and numerically in the context of fast ignition. K(alpha)-emission images reveal a collimated or scattered electron beam depending on the initial density and the compression timing. A numerical transport model shows that implosion-driven electrical resistivity gradients induce strong magnetic fields able to guide the electrons. The good agreement with measured beam sizes provides the first experimental evidence for fast-electron magnetic collimation in laser-compressed matter

Abstract

This paper presents the goals and some of the results of experiments conducted within the Working Package 10 (Fusion Experimental Programme) of the HiPER Project. These experiments concern the study of the physics connected to 'advanced ignition schemes', i.e. the fast ignition and the shock ignition approaches to inertial fusion. Such schemes are aimed at achieving a higher gain, as compared with the classical approach which is used in NIF, as required for future reactors, and make fusion possible with smaller facilities. In particular, a series of experiments related to fast ignition were performed at the RAL (UK) and LULI (France) Laboratories and studied the propagation of fast electrons (created by a short-pulse ultra-high-intensity beam) in compressed matter, created either by cylindrical implosions or by compression of planar targets by (planar) laser-driven shock waves. A more recent experiment was performed at PALS and investigated the laser-plasma coupling in the 10 16 W cm -2 intensity regime of interest for shock ignition. © 2011 IOP Publishing Ltd.

Abstract

Fast ignition requires a precise knowledge of fast electron propagation in a dense hydrogen plasma. In this context, a dedicated HiPER (High Power laser Energy Research) experiment was performed on the VULCAN laser facility where the propagation of relativistic electron beams through cylindrically compressed plastic targets was studied. In this paper, we characterize the plasma parameters such as temperature and density during the compression of cylindrical polyimide shells filled with CH foams at three different initial densities. X-ray and proton radiography were used to measure the cylinder radius at different stages of the compression. By comparing both diagnostics results with 2D hydrodynamic simulations, we could infer densities from 2 to 11 g/cm 3 and temperatures from 30 to 120 eV at maximum compression at the center of targets. According to the initial foam density, kinetic, coupled (sometimes degenerated) plasmas were obtained. The temporal and spatial evolution of the resulting areal densities and electrical conductivities allow for testing electron transport in a wide range of configurations. © 2011 American Institute of Physics.

Abstract

The effects of a soy protein diet on hematological, oxidant, and antioxidant levels in brain, liver, and pancreatic tissues in an animal model of simulated weightlessness were investigated in the current study. METHODS: Rats on a regular laboratory pellet diet or on 9.6% soy protein diet were either not suspended (non-HLS) or hind limb suspended (HLS) by their tails for 14 d. Body weights and food and water intakes were monitored and blood samples were analyzed for hematocrit, red blood cell mass, and hemoglobin before and after suspension. Brain, liver and pancreatic tissues were measured for oxidant and antioxidant levels. RESULTS: Body weights of the HLS animals were decreased compared with non-HLS animals (P < 0.05). Hematological variables were not different between the non-HLS and HLS groups. Malondialdehyde (MDA) levels in the brain and liver tissues were lower in the non-HLS soy group than the non-HLS group receiving the regular laboratory diet (P < 0.05). In HLS groups, however, these levels were higher for both diets, but it was only significant (P < 0.05) between the soy non-HLS and the soy HLS group. Basal superoxide dismutase (SOD) levels were not significantly different between the 2 diet groups but were elevated in HLS groups compared with the non-HLS groups (P < 0.05). Glutathione levels in the brains of non-HLS soy group were elevated (P < 0.05) but were not changed after 14 d of suspension. In contrast, glutathione levels in the livers of soy diet group were generally lower in both HLS and non-HLS animals. Malondialdehyde and SOD levels in the pancreatic tissue were not significantly different between groups. No consistent results were found for pancreatic glutathione levels. CONCLUSIONS: Our data suggest that HLS induced a differential tissue-specific oxidative response as determined by MDA, SOD, and glutathione levels. Soy protein in the diet lowered basal peroxide levels but did not affect changes in the peroxide levels induced by HLS. (Supported by a grant from Arkansas Space Grant Consortium.)
