Abstract

© 2017 American Chemical Society. Ultra-nanocrystalline diamond (UNCD) is increasingly being used in the fabrication of devices and coatings due to its excellent tribological properties, corrosion resistance, and biocompatibility. Here, we study its response to irradiation with kiloelectronvolt electrons as a controlled model for extreme ionizing environments. Real time Raman spectroscopy reveals that the radiation-damage mechanism entails dehydrogenation of UNCD grain boundaries, and we show that the damage can be recovered by annealing at 883 K. Our results have significant practical implications for the implementation of UNCD in extreme environment applications, and indicate that the films can be used as radiation sensors.

Abstract

The Pierre Auger Observatory is a facility built to detect air showers produced by cosmic rays above 1017 eV. During clear nights with a low illuminated moon fraction, the UV fluorescence light produced by air showers is recorded by optical telescopes at the Observatory. To correct the observations for variations in atmospheric conditions, atmospheric monitoring is performed at regular intervals ranging from several minutes (for cloud identification) to several hours (for aerosol conditions) to several days (for vertical profiles of temperature, pressure, and humidity). In 2009, the monitoring program was upgraded to allow for additional targeted measurements of atmospheric conditions shortly after the detection of air showers of special interest, e. g., showers produced by very high-energy cosmic rays or showers with atypical longitudinal profiles. The former events are of particular importance for the determination of the energy scale of the Observatory, and the latter are characteristic of unusual air shower physics or exotic primary particle types. The purpose of targeted (or "rapid") monitoring is to improve the resolution of the atmospheric measurements for such events. In this paper, we report on the implementation of the rapid monitoring program and its current status. The rapid monitoring data have been analyzed and applied to the reconstruction of air showers of high interest, and indicate that the air fluorescence measurements affected by clouds and aerosols are effectively corrected using measurements from the regular atmospheric monitoring program. We find that the rapid monitoring program has potential for supporting dedicated physics analyses beyond the standard event reconstruction.

27. Hydrodynamic Simulations and Soft X-Ray Laser Interferometric Studies of Energy Transport in Tightly Focused Laser-Heated Aluminum Plasmas.

Abstract

A plasma generated by a tightly focused ~ 14 μm (FWHM), 600 ps duration laser beam at an irradiance of 1013 W cm-2 on a flat aluminum target is investigated. We report new findings that give a better understanding of the energy transport mechanisms in the measured plasma. The formation of a small, on-axis dip or concave electron density profile is observed. Detailed modeling of the spatial and temporal profile of a laser-produced plasma with the 2-D LASNEX hydrodynamics code gives good agreement with the observed features. The observed cold plasma formation along the target surface hundreds of microns away from the small focal spot is generated by heated material outside of the laser focus. Plasma generated by low intensity wings in the laser spatial profile is augmented by soft x-ray radiation from the hot coronal plasma heated by the laser. The simulations show that the x-ray heating will produce a plasma outside the focal spot without the low intensity wings. Strong thermal electron conductive heating due to large thermal gradients continues to generate ablation outside the laser spot and formation of lobes on each side of the focal spot.

Abstract

Soft x-ray laser interferometry was used to study the evolution of dense colliding plasmas produced by laser irradiation of semi-cylindrical targets. We present a series of interferograms that map the evolution of 1 mm long Aluminum plasmas created by irradiating 500 μm diameter semi-cylindrical targets with an intensity of ~ 1.1× 1012 Wcm-2 from 120 ps duration laser pulses of 800 nm wavelength. The interferograms were obtained combining a 46.9 nm tabletop capillary discharge soft x-ray laser with a high throughput amplitude division interferometer based on diffraction gratings. The interferograms show that the plasma expands converging on the axis of the semi-cylindrical cavity where it reaches electron densities above 1× 1020 cm-3. The code HYDRA was used to simulate the plasmas expansion and give insight on the plasma dynamics. [ABSTRACT FROM AUTHOR]

Abstract

It is almost a decade since the first tabletop x-ray laser experiments were implemented at the Lawrence Livermore National Laboratory (LLNL). The decision to pursue the picosecond-driven schemes at LLNL was largely based around the early demonstration of the tabletop Ne-like Ti x-ray laser at the Max Born Institute (MBI) as well as the established robustness of collisional excitation schemes. These picosecond x-ray lasers have been a strong growth area for x-ray laser research. Rapid progress in source development and characterization has achieved ultrahigh peak brightness rivaling the previous activities on the larger facilities. Various picosecond soft-x-ray based applications have benefited from the increased repetition rates. We will describe the activities at LLNL in this area. [ABSTRACT FROM AUTHOR]

Abstract

It is long ago recognized that Z-pinches represent very natural medium for x-ray lasers (XRL) due to its favorable geometry and achievable high densities and temperatures. They also are very efficient x-ray sources. One of their variants, the capillary discharges, attracted attention of plasma physics researchers for almost two decades. It has been used for hot dense plasma formation and x-ray lasers, for transportation of laser beams and XUV radiation generation in x-ray iithography, for basic Z-pinch research and some others. The combination of efficiency, simplicity and low cost of capillary electrical discharges allowed to scale capillary x-ray lasers to table-top dimensions. In this paper we show the modeling results for next, 3-4 times shorter wavelength x-ray lasers. As an efficient x-ray source of line and continuum radiation it can be used for many practically important application in science and technology. In particular, the capillary discharge can appear as powerful potential candidate for emerging XUV microlithography. We present here the results of numerical modeling of spectra and density of Xe EUV source which involved plasma heating and dynamics, detailed atomic kinetics and radiation transport and material ablation physics.

Abstract

Soft x-ray laser interferograms of laser-created plasmas generated at moderate irradiation intensities (1x10[SUP11] - 7x10[SUP12] W cm[SUP-2]) with λ = 1.06 µm light pulses of ∼3 ns FWHM duration and narrow focus (∼30 µm) reveal the unexpected formation of an inverted density profile with a density minimum on axis and distinct plasma sidelobes. Model simulations show that this strong 2-dimensional hydrodynamic behavior is essentially a universal phenomenon that is the result of plasma radiation induced mass ablation and cooling in the areas surrounding the focal spot. These measurements, which mapped plasma densities up to 0.9x10[SUP21] cm[SUP-3], demonstrate the use of a portable soft x-ray laser interferometer as a high resolution tool for the study of high density plasma phenomena and the validation of hydrodynamic codes.

Abstract

We give an overview of recent capillary discharge-driven soft x-ray laser development experiments and applications ar Colorado State University. We report the demonstration of the first desktop size soft x-ray laser, a capillary discharge Ne-like Ar soft x-ray laser that was measured to emit laser pulses with energy up to 10 µJ at 46.9 nm. In relation to the development of capillary discharge lasers at shorter wavelengths, spectra of the highly ionized cadmium plasmas identified strong emission from the 4d[SUP1]S[SUB0]- 4p[SUP1]P[SUB1] laser transition of Ni-like Cd at 13.16 nm. We have also demonstrated optical guiding of intense laser pulses in the plasmas of ah Ar capillary discharge, a result that is of interest for the development of efficient longitudinally pumped collisional soft x -ray lasers in a gaseous media. In term of applications, we summarize our continued progress in establishing capillary discharge lasers as a compact soft x-ray source of coherent radiation for dense plasma diagnostics. The combination of a tabletop 46.9 nm capillary discharge Ne-like Ar laser and a Mach-Zehnder interferometer based on diffraction gratings was used to study two-dimensional hydrodynamic effects in laser-created plasmas. The short wavelength and high brightness of the capillary discharge soft x-ray laser allowed us to map the density profile up to ∼10[SUP21] cm[SUP-3], close to the critical density. The interferometry of laser-created plasmas created ar moderate irradiation intensity (0.1 -7 x 10[SUP12] W cm[SUP-2]) shows the development of a concave electron density profile that differ significantly from that expected for a classical expansion. Measurements involving line-focus and spot-focus laser created plasmas and hydrodynamic model simulations confirm this twodimensional effect is essentially a universal effect that exists over a wide space of plasma parameters. Ina separate experiments we have used the same soft x-ray laser interferometry tools... [ABSTRACT FROM AUTHOR]

Abstract

With laser-driven tabletop x-ray lasers now operating in the efficient saturation regime, the source characteristics of high photon flux, high monochromaticity, picosecond pulse duration, and coherence are well-matched to many applications involving the probing of matter undergoing rapid changes. We give an overview of recent experiments at the Lawrence Livermore National Laboratory (LLNL) Compact Multipulse Terawatt (COMET) laser using the picosecond 14.7 nm x-ray laser as a compact, ultrafast probe for sufface analysis and for interferometry of laser-produced plasmas. The plasma density measurements for known laser conditions allow us to reliably and precisely benchmark hydrodynamics codes. In the former case, the x-ray laser ejects photo-electrons, from the valence band or shallow core-levels of the material, and are measured in a time-of-flight analyzer. Therefore, the electronic structure can be studied directly to determine the physical properties of materials undergoing rapid phase changes. [ABSTRACT FROM AUTHOR]

Abstract

We present the first results from soft x-ray laser interferometry measurements of current-driven thin wire explosions obtained using a capillary discharge pumped 46.9 nm laser and an amplitude division interferometer based on diffraction gratings. We have obtained series of high-resolution soft x-ray interferograms/shadowgrams that depict the initial stage of the evolution of exploding Al wires 15 µm and 25 µm in diameter. The images show a dense vapor core that completely absorbs the probe beam during the initial part of the explosion, and a surrounding plasma shell where both a shift of the interference fringes and partial absorption of the soft x-ray laser probe beam are observed. The excitation of the 25 µm diameter wires ata current rate of 30 A/ns is observed to result in the uniform expansion. However, an increase of the rate of energy deposited per unit mass is observed to give rise to significant instabilities. The expansion velocity of the wire core was determined from the variation ofthe measured absorption width of the soft x-ray laser beam. The determination of the electron density and vapor density profile requires the combined analysis of the soft x-ray absorption and fringe shift data. [ABSTRACT FROM AUTHOR]

Abstract

Ultra-nanocrystalline diamond (UNCD) is increasingly being used in the fabrication of devices and coatings due to its excellent tribological properties, corrosion resistance, and biocompatibility. Here, we study its response to irradiation with kiloelectronvolt electrons as a controlled model for extreme ionizing environments. Real time Raman spectroscopy reveals that the radiation-damage mechanism entails dehydrogenation of UNCD grain boundaries, and we show that the damage can be recovered by annealing at 883 K. Our results have significant practical implications for the implementation of UNCD in extreme environment applications, and indicate that the films can be used as radiation sensors.
