Book excerpt: Recent progress in x-ray spectroscopy from laser plasmas is reviewed. Advances in the use of K-shell spectra as a diagnostic tool is discussed. Much activity in understanding complex spectra especially from Ne I and Ni I isoelectronic series have been made. Much of the progress has been due to observation of amplification from .delta.n = O transitions from these configurations. The spectroscopy will be discussed and examples of spectra of the amplified lines will be shown. Finally, recent work on using x-ray spectroscopy to diagnose high density implosions will be discussed. 33 refs.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents advances in X-ray spectroscopy of plasmas interacting with a laser radiation and laser-induced plasmas. This research is practically important for the quest for the controlled nuclear fusion, for studying matter under extreme conditions, for providing atomic reference data, for laboratory modelling of physical processes in astrophysical objects, and for a better understanding of intense laser-plasma interactions. Advances in X-Ray Spectroscopy of Laser Plasmas significantly expands the scope of practical applications of X-ray spectroscopy of laser plasmas compared to traditional X-ray diagnostics of laser plasmas. The recent advances presented in this text make it possible to study the development of Langmuir waves, ion acoustic waves, transverse electromagnetic waves, parametric decay instabilities, as well as the rates of charge exchange between multicharged ions. Key Features Presents novel methods of X-Ray spectroscopy for both non-relativistic and relativistic laser-plasma interactions Includes methods of the X-Ray spectroscopy for measuring ultra-intense magnetic fields in laser plasmas Examines advanced designs of plasma-tunable X-ray lasers Demonstrates various analytical formalisms underlying the advances described in the book

Available in PDF, EPUB and Kindle. Book excerpt: The volumetric heating of a thin copper target has been studied with time resolved x-ray spectroscopy. The copper target was heated from a plasma produced using the Lawrence Livermore National Laboratory's Compact Multipulse Terrawatt (COMET) laser. A variable spaced grating spectrometer coupled to an x-ray streak camera measured soft x-ray emission (800-1550 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: A pulse train laser with low peak power can heat a dense plasma effectively and promote ionization of atoms up to higher stages such as lithium-like aluminum. This fact was proved by soft x-ray spectra. X-ray emission from laser produced plasma has been extensively studied for many years and now has found new promising application in variety of field, including, for example, various forms of x-ray spectroscopy, x-ray laser, as well as microscopy and lithography.

Book excerpt: The intensity and spectral characteristics of x-ray emitted from laser-produced plasmas have been investigated computatinoally and experimentally. a two-dimensional implosi code was used successfully to calculate laser-plasma radiation characteristics and to aid in the design of laser targets for high-yield x-ray production. Other computer codes, in use or under development predict lime strengths and energies for laser-plasma x-ray emission. An experimental effort is aimed at reliable measurements of x-ray yields and spectra. a wide variety of x-ray detection methods have been evaluated, and x-ray yields have been measured from plasmas produced with two dissimilar laser systems. The high energy x-ray spectrum, from about 10 to 140 keV, has been studied using high-gain scintillatino detectors and thick K-edge filters. Various supplementary measurements have provided information concerning characteristics of the target-reflected laser light, the ion energies, and the laser intensity patterns.

Available in PDF, EPUB and Kindle. Book excerpt: High intensity, frequency-tripled, focused light from a multibeam laser system (OMEGA) was utilized to generate plasma of highly-ionized atoms. This work involves the accurate wavelength measurements of 2p-3d,3s,4d,4s lines in L-series spectra of transition elements. The data were collected with high-resolution x-ray spectrographs. The observed lines were classified based on ab initio, atomic structure calculations using adjusted Slater parameters. The spectral results are presented as isoelectronic sequences of the observed and calculated wavelengths for the Li-, Be-, and B-like stages of ionization from atomic numbers 22 (Ti) through 32 (Ge).

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Spectroscopic investigations of the x-ray emission of plasmas heated by 120 ps, frequency doubled pulses from the JANUS Nd: glass laser are presented. High Z K-shell spectra emitted from slab targets heated to near 10[sup 17] W cm[sup[minus]2] intensity are investigated. High resolution ([gamma]/[Delta][gamma]>5000) x-ray spectra of multicharged ions of H-like Ti, Co, Ni, Cu, and also H-like Sc in the spectral range 1.5--3.0[angstrom] are obtained in single laser shots using a spherically bent Mica crystal spectrograph with a 186 mm radius of curvature. The spectra- have one dimensional spatial resolution of about 25[mu]m and indicate that the size of the emission zone of the resonance, transitions is25[mu]m. Simultaneous x-ray images of the plasma from a charge-coupled device pinhole camera confirmed that the plasma x-ray emission is from a similar sized source. Survey spectra[gamma]/[Delta][gamma]=500--1000) taken with a flat LiF (200) crystal spectrometer with a charge-coupled device detector complement the high resolution data. Two dimensional LASNEX modeling of the laser target conditions indicate that the high K-shell charge states are produced in the hot dense region of the plasma with electron temperature2 keV and density[approximately]10[sup 22] cm[sup[minus]3]. These experiments demonstrate that with modest laser energy, plasmas heated by high-intensity 120 ps lasers provide a very bright source of hard[approximately]8 keV x-ray emission.

Available in PDF, EPUB and Kindle. Book excerpt: We have examined the underdense plasma conditions of laser irradiated disks using K x-rays from highly ionized ions. A 900 ps laser pulse of 0.532 .mu.m light is used to irradiate various Z disks which have been doped with low concentrations of tracer materials. The tracers whose Z's range from 13 to 22 are chosen so that their K x-ray spectrum is sensitive to typical underdense plasma temperatures and densities. Spectra are measured using a time-resolved crystal spectrograph recording the time history of the x-ray spectrum. A spatially-resolved, time-integrated crystal spectrograph also monitors the x-ray lines. Large differences in Al spectra are observed when the host plasma is changed from SiO2 to PbO or In. Spectra will be presented along with preliminary analysis of the data.

This book was released on 1979 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: X-ray spectra from CH2 laser-generated at 10 to the 16th power W/Sq cm are compared with those obtained using a 2D-mhd code. Good agreement is found over 7 orders of magnitude for X-ray energies comprised between 1 and 300 keV. It is found that the hard X-ray spectrum is compatible with the generation of B-fields in the interaction region. Variation of the numerical results with initial conditions, ion mass, laser energy deposition and grid size is investigated. (Author).
