The copper target was heated by a plasma produced using the Lawrence Livermore National Laboratory's Compact Multipulse Terawatt (COMET) laser. A variable spaced grating spectrometer coupled to an x-ray streak camera measured soft x-ray emission (800 - 1450 eV) from the back of the copper target to characterize the bulk heating of the target. Radiation hydrodynamic simulations were modeled in 2-dimensions using the HYDRA code. The target conditions calculated by HYDRA were post-processed with the atomic kinetics code CRETIN to generate synthetic emission spectra. A comparison between the experimental and simulated spectra indicates the presence of specific ionization states of copper and the corresponding electron temperatures and ion densities throughout the laser-heated copper target.

Book excerpt: Time-resolved x-ray photoelectron spectroscopy is used to probe the non-steady-state evolution of the valence band electronic structure of laser heated ultra-thin (50 nm) Cu. Single-shot x-ray laser induced time-of-flight photoelectron spectroscopy with picosecond time resolution is used in conjunction with optical measurements of the disassembly dynamics that have shown the existence of a metastable liquid phase in fs-laser heated Cu foils persisting 4-5 ps. This metastable phase is studied using a 527 nm wavelength 400 fs laser pulse containing 0.1-2.5 mJ laser energy focused in a large 500 x 700 [mu]m2 spot to create heated conditions of 0.07-1.8 x 1012 W cm−2 intensity. Valence band photoemission spectra showing the changing occupancy of the Cu 3d level with heating are presented. These are the first picosecond x-ray laser time-resolved photoemission spectra of laser-heated ultra-thin Cu foil showing changes in electronic structure. The ultrafast nature of this technique lends itself to true single-state measurements of shocked and heated materials.

Available in PDF, EPUB and Kindle. Book excerpt: Plasma Atomic Physics provides an overview of the elementary processes within atoms and ions in plasmas, and introduces readers to the language of atomic spectra and light emission, allowing them to explore the various and fascinating radiative properties of matter. The book familiarizes readers with the complex quantum-mechanical descriptions of electromagnetic and collisional processes, while also developing a number of effective qualitative models that will allow them to obtain adequately comprehensive descriptions of collisional-radiative processes in dense plasmas, dielectronic satellite emissions and autoionizing states, hollow ion X-ray emissions, polarized atoms and ions, hot electrons, charge exchange, atomic population kinetics, and radiation transport. Numerous applications to plasma spectroscopy and experimental data are presented, which concern magnetic confinement fusion, inertial fusion, laser-produced plasmas, and X-ray free-electron lasers’ interaction with matter. Particular highlights include the development of quantum kinetics to a level surpassing the almost exclusively used quasi-classical approach in atomic population kinetics, the introduction of the recently developed Quantum-F-Matrix-Theory (QFMT) to study the impact of plasma microfields on atomic populations, and the Enrico Fermi equivalent photon method to develop the “Plasma Atom”, where the response properties and oscillator strength distribution are represented with the help of a local plasma frequency of the atomic electron density. Based on courses held by the authors, this material will assist students and scientists studying the complex processes within atoms and ions in different kinds of plasmas by developing relatively simple but highly effective models. Considerable attention is paid to a number of qualitative models that deliver physical transparency, while extensive tables and formulas promote the practical and useful application of complex theories and provide effective tools for non-specialist readers.

Available in PDF, EPUB and Kindle. Book excerpt: The motivating idea of the first Topical Meeting on Picosecond Phenomena, which took place at Hilton Head Island in 1978, was to bring together scien tists and engineers in a congenial setting who were developing picosecond lasers with those who were applying them to problems in chemistry, physics, electronics, and biology. The field has advanced remarkably in the following six years. This is reflected in the size of the conference which has more than doubled in the past six years and now includes scientists from many countries around the world. As evidenced by the papers in this volume, the appl ication of ultrafast 1 ight pulses continues to grow in new and diverse directions encompassing an increasingly wide range of subject areas. This progress has gone hand-in-hand with the development of new and more precise methods of generating and measuring ultrafast light pulses, which now extend well into the femtosecond time domain. It was this latter advance which was responsible for changing the name of the conference to Ultrafast Phenomena. The 1984 meeting was held at the Monterey Conference Center in Monterey, Cal ifornia from June 11 to 15 under the sponsorship of the Optical Society of America. A total of 320 registered participants, including 65 students, attended the three and one-half day conference. The overall enthusiasm of the participants, the high quality of the research presented, and ambiance of the setting combined to produce a successful and enjoyable conference.

Available in PDF, EPUB and Kindle. Book excerpt: The main goal of this thesis was to extend and apply time resolved x-ray scattering experiments at in-house, synchrotron and free electron laser sources to soft matter sample systems, in particular aligned lipid multilayers on solid support. A special emphasis was placed on a characterization of the non-equilibrium fast time response of the multilamellar stack to shortly pulsed optical excitation as well as the acousto-electric field accompanying a surface acoustic wave (SAW). In addition to fundamental questions associated with non-equilibrium dynamics of soft matter films such as driven membrane undulations, this thesis addresses technological challenges of time resolved x-ray diffraction, in particular concerning the timing scheme that has been implemented at the synchrotron storage ring Petra III, DESY, Hamburg. Importantly, a conceptually new pulse resolved x-ray detection scheme, well exceeding the performance of present detector concepts, has been developed and is described in detail.

Available in PDF, EPUB and Kindle. Book excerpt: The Fourth American Physical Society Topical Conference on Shock Waves in Condensed Matter was held in Spokane, Washington, July 22-25, 1985. Two hundred and fifty scientists and engineers representing thirteen countries registered at the conference. The countries represented included the United States of America, Australia, Canada, The People's Repub lic of China, France, India, Israel, Japan, Republic of China (Taiwan), United Kingdom, U. S. S. R, Switzerland and West Germany. One hundred and sixty-two technical papers, cov ering recent developments in shock wave and high pressure physics, were presented. All of the abstracts have been published in the September 1985 issue of the Bulletin of the American Physical Society. The topical conferences, held every two years since 1979, have become the principal forum for shock wave studies in condensed materials. Both formal and informal technical discussions regarding recent developments conveyed a sense of excitement. Consistent with the past conferences, the purpose of this conference was to bring together scientists and engineers studying the response of condensed matter to dynamic high pressures and temperatures. Papers covering experimental, theoretical, and numerical studies of con densed matter properties were presented. A noteworthy feature of this conference was the participation by several leading scientists engaged in static high pressure research. Donald Curran served as the Master of Ceremonies at the conference banquet, which was at tended by two hundred and seventy-five conference participants and guests including Dr. Samuel Smith, the new President of Washington State University.
