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.

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

Papers from the April 1995 conference (formerly called a "workshop") are contained in two volumes. The first volume (623-9) comprises contributions arranged in sections on ICF programs and energy drivers; critical elements for ignition--target experiment, physics, and design; laser-matter interaction physics; and high intensities, short pulse interactions. The second volume (624-7) begins with papers on optical technologies and various kinds of lasers--free electron, LD and LD pumped, gas, nuclear pumped, and short pulse. Following these are sections on particle beams--light and heavy ion beam fusions; and applications of laser and plasma. Edward Teller Award lectures complete the proceedings. Not indexed by subject (contains only an author "index"). Annotation copyrighted by Book News, Inc., Portland, OR

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.

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.

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.

Soft X-rays have great potential for use in a wide variety of applications, including the semiconductor industry and the life sciences. X-Rays from Laser Plasmas: Generation and Applications focuses exclusively and in detail on the science and technology of soft X-rays produced with non-synchrotron sources. Using a minimum of mathematical formulae, it discusses how such X-rays can be efficiently and economically generated from plasmas produced by lasers, and how they interact with matter. Authored by Dr Edmond Turcu, one of the pioneers in this field, X-Rays from Laser Plasmas: Generation and Applications will be of great interest to a wide variety of readers, including all those working in X-ray lithography, microscopy, and radiobiology.
