Available in PDF, EPUB and Kindle. Book excerpt: Large magnetic fields are produced near the target when a powerful laser pulse is focused onto a solid target. A discussion is given of how the laser radiation produces conditions in the laser-produced plasma which allow the conversion of thermal energy to magnetic field energy. This concept of a thermal source generating the magnetic field is illustrated by deriving the source function for a spherical plasma. It is shown that the necessary nonadiabatic conditions exist in the presence of laser radiation. At a sufficiently high intensity (approximately 10 to the 14th power W/square cm), the linear polarization of the radiation produces a corresponding anisotropy in the electron velocity distribution. Magnetic sources then exist for any spatial variation of pressure and density. Sources due to the direct action of radiation pressure are also discussed. This implies that part of the laser radiation is absorbed by direct conversion (no heating) from laser field energy to magnetic field energy. An estimate is made of the magnetic field produced in the region where laser radiation is being absorbed. Such fields can be quite large--in the megagauss range. (Author).

Book Synopsis Rayleigh-Taylor-Induced Electromagnetic Fields in Laser-produced Plasmas by : Mario John-Errol Manuel
Download or read book Rayleigh-Taylor-Induced Electromagnetic Fields in Laser-produced Plasmas written by Mario John-Errol Manuel and published by . This book was released on 2013 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spontaneous electromagnetic fields can be important to the dynamic evolution of a plasma by directing heat flow as well as providing additional pressures on the conducting fluids through the Lorentz force. Electromagnetic fields are predicted to affect fluid behavior during the core-collapse of supernovae through generation of fields due to hydrodynamic instabilities. In the coronae of stars, self-generated magnetic fields lead to filamentary structure in the hot plasma. Recent experiments by Gregori et al. investigated sources of protogalactic magnetic fields generated by laser-produced shock waves. In inertial confinement fusion experiments, self-generated electromagnetic fields can also play a role and have recently become of great interest to the community. Present day laser facilities provide a unique opportunity to study spontaneous field-generation in these extreme environments under controlled conditions. Instability-induced electromagnetic fields were investigated using a novel monoenergetic-proton radiography system. Fusion protons generated by an 'exploding-pusher' implosion were used to probe laser-irradiated plastic foils with various preimposed surface perturbations. Imaging protons are sensitive to electromagnetic fields and density modulations in the plasma through the Lorentz force and Coulomb collisions, respectively. Corresponding x-ray radiographs of these targets provided mass density distributions and Coulomb effects on protons were assessed using a Monte Carlo code written using the Geant4 framework. Proton fluence distributions were recorded on CR-39 detectors and Fourier analyzed to infer path-integrated field strengths. Rayleigh-Taylor (RT) growth of preimposed surface perturbations generated magnetic fields by the RT-induced Biermann battery and were measured for the first time. Good data were obtained during linear growth and when compared to ideal calculations, demonstrated that field diffusion near the source played an important role. At later times in the plasma evolution, 3-D cellular structures were observed for all foil types. These features were found to be analogous to previously observed filamentary field structures by Séguin et al. in laser-driven spherical targets. Face-on images of these field structures provided good data to quantitatively analyze the size of these features, not previously attainable due to the complexity of the 3-D spherical data. Work presented here demonstrates that these field structures are likely caused by the magnetothermal instability in the underdense corona.

This book was released on 1975 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: A quantum-rate analysis of laser-induced breakdown in deuterium and helium gas was used to predict the dependence of the breakdown threshold intensity on gas pressure, laser pulse length, and the magnitude of an applied external magnetic field parallel to the direction of propagation of the laser beam. Diffusion, elastic and inelastic collisions, and multiphoton ionization of atomic and molecular states excited by electron impact were considered.

Book Synopsis Influence of a Static Magnetic Field on Laser Induced Tungsten Plasma in Air by :

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: In this work, laser induced tungsten plasma has been investigated in the absence and presence of 0.6 T static transverse magnetic field at atmospheric pressure in air. The spectroscopic characterization of laser induced tungsten plasma was experimentally studied using space-resolved emission spectroscopy. The atomic emission lines of tungsten showed a significant enhancement in the presence of a magnetic field, while the ionic emission lines of tungsten presented little change. Temporal variation of the optical emission lines of tungsten indicated that the atomic emission time in the presence of a magnetic field was longer than that in the absence of a magnetic field, while no significant changes occurred for the ionic emission time. The spatial resolution of optical emission lines of tungsten demonstrated that the spatial distribution of atoms and ions were separated. The influence of a magnetic field on the spatial distribution of atoms was remarkable, whereas the spatial distribution of ions was little influenced by the magnetic field. The different behaviors between ions and atoms with and without magnetic field in air were related to the various atomic processes especially the electrons and ions recombination process during the plasma expansion and cooling process.
Book Synopsis Short Wavelength Laboratory Sources by : Davide Bleiner
Download or read book Short Wavelength Laboratory Sources written by Davide Bleiner and published by Royal Society of Chemistry. This book was released on 2014-12-04 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our ability to manipulate short wavelength radiation (0.01-100nm, equivalent to 120keV-12eV) has increased significantly over the last three decades. This has lead to major advances in applications in a wide range of disciplines such as: the life and medical sciences, including cancer-related studies; environmental science, including studies of pollution and its effects; archaeology and other cultural heritage disciplines; and materials science. Although expansion in application areas is due largely to modern synchrotron sources, many applications will not become widespread, and therefore routinely available as analytical tools, if they are confined to synchrotrons. There is a need to develop bright but small and low cost X-ray sources, not to replace synchrotrons but to complement them and this book will look at how to facilitate these developments. Written by a distinguished team of international authors, this book is based on the COST Action MP0601: Short Wavelength Laboratory Sources. The contents are divided into five main sections. the introductory section provides a comprehensive introduction to the fundamentals of radiation, generation mechanisms and short wavelength laboratory sources. The middle sections focus on modelling and simulation, source development: improvement and characterisation and integrated systems: sources, optics and detectors. The final section looks at recent applications. Aimed at academic and industrial researchers in physical chemistry and chemical physics, the contents provides practical information about the implementation of short wavelength laboratory sources and their applications.
