This book was released on 2015 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: X-ray Thomson scattering (XRTS) is the combination of elastic Raleigh scattering and inelastic Compton scattering observed from high density systems using energetic probe energies at the keV x-ray level. Thermal x-ray probes have historically been created by delivering 1014 [-] 1016 W/cm2 to a mid-Z metal foil such as titanium using kilojoule-class lasers. An XRTS probe source must provide adequate photon numbers within a finite bandwidth in order to resolve the elastic and inelastic scattering features. This thesis argues that the 4.75 keV He[alpha] spectral feature from a titanium hybrid x-pinch x-ray source driven in a pulsed power circuit can satisfy these photon and bandwidth requirements and function as an XRTS probe source. The arguments are supported through xray diode and image plate photometric analysis for the titanium He[alpha] feature. As a proof of principle, scattering signals from cold, static materials have been collected using the hybrid x-pinch as the probe source. Two different experimental scattering arrangements were developed to collect the weak scattered signals from room temperature targets. The hybrid xpinch was driven in the main current path of the Cornell Beam Research Accelerator (COBRA) 1 MA pulsed power driver for both of these arrangements. The first setup, Focused XRTS (FXRTS), used a spherically-bent germanium xray optic to focus the probe photons collected from a titanium hybrid x-pinch approximately 82 cm away, and focused them onto a 20 [MICRO SIGN]m thick aluminum foil scattering target. The FXRTS setup allowed the entire scattering experiment to be spatially removed from the actual source location, thus lowering background signals on the detectors. For the second scattering setup, Direct XRTS (DXRTS), a new spectrometer was designed and built to function inside the main COBRA vacuum chamber. The scattering setup functioned in a more traditional sense by having the scattering target, 125 [MICRO SIGN]m thick graphite, placed approximately 20 mm away from the x-pinch x-ray source. Protection of the optics and background noise shielding for the detectors were design challenges in the spectrometer. For both experimental arrangements, the backscattered radiation was collected using high-efficiency highly annealed pyrolytic graphite (HAPG) optics and focused onto Fuji Biological Analysis Systems - Tritium type (BAS-TR) image plate detectors. The noncollective FXRTS results from aluminum show the importance of the ion-ion correlation factor within the total dynamic structure factor and its strong dependence on scattering angle. The FXRTS results were fit with theoretical scattering spectrums created using an XRTS subroutine included in the SPECT3D spectral code suite. Unfortunately, the noncollective DXRTS results from graphite were mixed with line and continuum radiation from other sources that made detailed analysis impossible.

This book was released on 2016 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments on the Sandia Z pulsed-power accelerator demonstrated the ability to produce warm dense matter (WDM) states with unprecedented uniformity, duration, and size, which are ideal for investigations of fundamental WDM properties. For the first time, space-resolved x-ray Thomson scattering (XRTS) spectra from shocked carbon foams were recorded on Z. The large (> 20 MA) electrical current produced by Z was used to launch Al flyer plates up to 25 km/s. The impact of the flyer plate on a CH2 foam target produced a shocked state with an estimated pressure of 0.75 Mbar, density of 0.52 g/cm3, and temperature of 4.3 eV. Both unshocked and shocked portions of the foam target were probed with 6.2 keV x-rays produced by focusing the Z-Beamlet laser onto a nearby Mn foil. The data is composed of three spatially distinct spectra that were simultaneously captured with a single spectrometer with high spectral (4.8 eV) and spatial (190 [mu]m) resolutions. Furthermore, these spectra provide detailed information on three target locations: the laser spot, the unshocked foam, and the shocked foam.

Available in PDF, EPUB and Kindle. Book excerpt: These proceedings comprise of invited and contributed papers presented at the 13th International Conference on X-Ray Lasers (ICXRL 2012) which was held 11–15 June 2012 in Paris, France, in the famous Quartier Latin, inside the historical Center of Cordeliers. This conference is part of a continuing series dedicated to recent developments and applications of x-ray lasers and other coherent x-ray sources with attention to supporting technologies and instrumentation. New results in the generation of intense coherent x-rays and progress towards practical devices and their applications are reported in these proceedings, including areas of research in plasma-based x-ray lasers, 4th generation accelerator-based sources and higher harmonic generation. Recent achievements related to the increase of the repetition rate up to 100 Hz and shorter wavelength collisional plasma-based soft x-ray lasers down to about 7 nm are presented. Seeding the amplifying plasma with a femtosecond high-order harmonic of infrared laser was foreseen as the required breakthrough to break the picosecond frontier. Numerical simulations based on the Maxwell-Bloch model are presented in these proceedings, transposing the chirped pulse amplification technique to the x-ray domain in order to increase the time over which the femtosecond seed can be amplified. These proceedings also include innovative applications of soft x–ray lasers based on techniques and diagnostics relevant to topical domains such as EUV lithography, inertial confinement fusion, or warm dense matter physics.

This book was released on 2013-04-17 with total page 615 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of a NATO Advanced Study Institute entitled "Characterization of Crystal Growth Defects by X-ray Methods' held in the University of Durham, England from 29th August to 10th September 1979. The current interest in electronic materials, in particular silicon, gallium aluminium arsenide, and quartz, and the recent availability of synchrotron radiation for X-ray diffraction studies made this Advanced Study Institute particularly timely. Two main themes ran through the course: 1. A survey of the various types of defect occurring in crystal growth, the mechanism of their different methods of generation and their influence on the properties of relativelY perfect crystals. 2. A detailed and advanced course on the observation and characterization of such defects by X-ray methods. The main emphasis was on X-ray topographic techniques but a substantial amount of time was spent on goniometric techniques such as double crystal diffractometry and gamma ray diffraction. The presentation of material in this book reflects these twin themes. Section A is concerned with defects, Section C with techniques and in linking them. Section B provides a concise account of the basic theory necessary for the interpretation of X-ray topographs and diffractometric data. Although the sequence follows roughly the order of presentation at the Advanced Study Institute certain major changes have been made in order to improve the pedagogy. In particular, the first two chapters provide a vital, and seldom articulated, case for the need for characterization for crystals used in device technologies.

Book excerpt: Advances in the development of laser-produced x-ray sources have enabled a new class of high-energy density physics experiments. Powerful narrow-bandwidth x rays penetrate through short-lived hot dense states of matter and probe the physical properties with spectrally resolved x-ray scattering. Experiments from isochorically-heated plasmas with electron densities in the range of solid density and above have been demonstrated allowing for the first time exploration of the microscopic properties of dense matter regime close to strongly-coupled and Fermi degenerate conditions. Backscatter measurements have accessed the non-collective Compton scattering regime, which provides accurate diagnostic information on the temperature, density and ionization states. The forward scattering spectrum has been shown to measure the collective plasmon oscillations. Besides extracting the standard plasma parameters, density and temperature, forward scattering yields new observables such as a direct measure of collisions, quantum effects and detailed balance. In this talk, we will discuss new results important for applications of this technique for novel experiments in a wide range of research areas such as inertial confinement fusion, radiation-hydrodynamics, material science, and laboratory astrophysics.
