Available in PDF, EPUB and Kindle. Book excerpt: The warm density matter regime of high energy density physics [1, 2, 3] has a high scientific discovery potential for the properties of plasmas at high densities and pressures and at moderate temperatures (kT) in which the Coulomb interaction energy between plasma particles exceed kT. This leads to correlations in the plasma characterized by the dimensionless ''coupling'' parameter [Lambda]> 1, where [Lambda] is defined by [Lambda] = q[sup 2]n[sup 1/3]/kT. Here q is the effective ion charge and n the ion density. Strongly-coupled plasmas with [Lambda]> 1 are difficult to study analytically and by numerical simulation. Many astrophysical systems (e.g., brown dwarfs, and giant planets) and inertial fusion plasmas in the beginning stages of compression fall into this regime. There is an opportunity to develop improved understanding and models through accurate measurements of properties in the large parameter space of temperature and density where data is currently limited or non-existent. X-ray free-electron lasers (Fourth generation light sources), ultra-short pulse and high energy optical lasers, pulsed-power z-pinch x-ray sources, and high explosives are all capable of producing warm dense matter conditions at various temperatures, pressures, and sample sizes. Therefore, the challenge is not how to create warm dense matter conditions, but to create it so that it's fundamental properties can be best studied. The goal is to advance this field of science through a variety of complementary facilities and methods which offer several combinations of desirable attributes: Precise control and uniformity of energy deposition; Large sample sizes compared to diagnostic resolution volumes; A benign environment for diagnostics (low debris and radiation background); High shot rates (10/hour to 1/second) and multiple beamlines/target chambers; and Sites with easy access for broad participation by university scientists and students; and with the technical support for designing and fielding targets for qualified experiments.

Available in PDF, EPUB and Kindle. Book excerpt: As part of its current physics decadal survey, Physics 2010, the NRC was asked by the DOE, NSF, and NASA to carry out an assessment of and outlook for the broad field of plasma science and engineering over the next several years. The study was to focus on progress in plasma research, identify the most compelling new scientific opportunities, evaluate prospects for broader application of plasmas, and offer guidance to realize these opportunities. The study paid particular attention to these last two points. This "demand-side" perspective provided a clear look at what plasma research can do to help achieve national goals of fusion energy, economic competitiveness, and nuclear weapons stockpile stewardship. The report provides an examination of the broad themes that frame plasma research: low-temperature plasma science and engineering; plasma physics at high energy density; plasma science of magnetic fusion; space and astrophysical science; and basic plasma science. Within those themes, the report offers a bold vision for future developments in plasma science.

Download or read book Laser Interactions with Atoms Solids and Plasmas written by Richard M. More and published by Springer Science & Business Media. This book was released on 2013-11-21 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this NATO Advanced Study Institute was to bring together scientists and students working in the field of laser matter interactions in order to review and stimulate developmentoffundamental science with ultra-short pulse lasers. New techniques of pulse compression and colliding-pulse mode-locking have made possible the construction of lasers with pulse lengths in the femtosecond range. Such lasers are now in operation at several research laboratories in Europe and the United States. These laser facilities present a new and exciting research direction with both pure and applied science components. In this ASI the emphasis is on fundamental processes occurring in the interaction of short laser pulses with atoms, molecules, solids, and plasmas. In the case of laser-atom (molecule) interactions, high power lasers provide the first access to extreme high-intensity conditions above 10'8 Watts/em', a new frontier for nonlinear interaction of photons with atoms and molecules. New phenomena observed include multiphoton ionization processes, atomic collisions in the presence of a strong laser field, Coulomb explosion following rapid ionization of a molecule and the production of high harmonics of the laser source. Another important topic reviewed in this ASI is the lasercooling ofatoms.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the most recent, relevant, comprehensive and significant aspects in the well-established multidisciplinary field Laboratory Astrophysics. It focuses on astrophysical environments, which include asteroids, comets, the interstellar medium, and circumstellar and circumplanetary regions. Its scope lies between physics and chemistry, since it explores physical properties of the gas, ice, and dust present in those systems, as well as chemical reactions occurring in the gas phase, the bare dust surface, or in the ice bulk and its surface. Each chapter provides the necessary mathematical background to understand the subject, followed by a case study of the corresponding system. The book provides adequate material to help interpret the observations, or the computer models of astrophysical environments. It introduces and describes the use of spectroscopic tools for laboratory astrophysics. This book is mainly addressed to PhD graduates working in this field or observers and modelers searching for information on ice and dust processes.
Download or read book High Energy Density Physics written by R. Paul Drake and published by Springer Science & Business Media. This book was released on 2006-08-31 with total page 542 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has two goals. One goal is to provide a means for those new to high-energy-density physics to gain a broad foundation from one text. The second goal is to provide a useful working reference for those in the ?eld. This book has at least four possible applications in an academic c- text. It can be used for training in high-energy-density physics, in support of the growing number of university and laboratory research groups working in this area. It also can be used by schools with an emphasis on ultrafast lasers, to provide some introduction to issues present in all laser–target - perimentswithhigh-powerlasers,andwiththoroughcoverageofthematerial in Chap. 11 on relativistic systems. In addition, it could be used by physics, applied physics, or engineering departments to provide in a single course an introduction to the basics of ?uid mechanics and radiative transfer, with d- matic applications. Finally, it could be used by astrophysics departments for a similar purpose, with the parallel bene?t of training the students in the similarities and di?erences between laboratory and astrophysical systems. The notation in this text is deliberately sparse and when possible a given symbol has only one meaning. A de?nition of the symbols used is given in Appendix A. In various cases, additional subscripts are added to distinguish among cases of the same quantity, as for example in the use of ? and ? 1 2 to distinguish the mass density in two di?erent regions.
Download or read book Channeling Experiments on OMEGA EP written by Steven Ivancic and published by . This book was released on 2015 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The creation of stable, straight channels in dense plasma with high intensity laser beams is of interest to a number of applications in laser-produced plasma science. This includes the generation of MeV to GeV electron beams in laser wakefield accelerators (LWFA), coherent and brilliant X-ray generation from electron betatron radiation, and fast ignition of inertial confinement fusion targets (FI ICF). This thesis studies the creation of channels through dense preformed plasma on the OMEGA EP laser system. A new optical probing method was developed to image the channeling process. The experiments show that the channel bores faster than the ponderomotive hole boring velocity of Wilks et al. predicted by a balance of light pressure at the channel front. In the wake of the channeling pulse, a shock-driven parabolic density profile exists in the radial direction, allowing for the guiding of a subsequent high intensity pulse to an embedded steep gradient. A structure of this type is beneficial to the applications mentioned above. The results of this study can be extended to an integrated FI experiment on OMEGA, planned for the upcoming year. Current laser systems are able to create high energy density (HED) systems where the radiation-pressure in the laser field totally overwhelms the thermal pressure of the material. In this radiation-pressure dominated regime, the radiation-pressure, 2I/c, where I is the intensity of the radiation field and c the speed of light, is orders of magnitude greater than the thermal pressure, nkBT, where n is the material density and kBT is the specific energy of the system. This radiation-pressure driven flow modifies the plasma density in the region of the laser. This work presents measurements of a channel or density cavitation bored into an inhomogeneous HED plasma. A high-energy chirped-pulse amplification (CPA) laser beam (> I ~ 1018 W/cm2) was used to drive a radiation-pressure driven blast-wave into the plasma. A 10-ps, 10-mJ, 3.6 [mu]m resolution optical probing system was developed to image the interaction with unparalleled resolution with high spatial and temporal resolution. In a second experiment, a second, co-propagating high-intensity pulse was guided through the blast-wave prepared channel established by the first pulse. The pulse is transmitted efficiently and maintains a spatial profile close to the vacuum mode. This is most likely due to the intense heating experienced by the plasma during the channeling beam. The experimental data show a self-similar cylindrical blast-wave developing from the channeling laser. The forward velocity of the channel is measured and is quantitatively consistent with a radiation-pressure driven flow model that predicts the propagation velocity. The residual plasma in the channel is heated to multi-MeV temperatures (11,000,000,000 K) and the long time expansion (~ 500 ps) is consistent with 2-D radiation-hydrodynamics simulations. This work shows the creation of radiation-pressure driven flows in plasma. The creation of these conditions may be scaled to a regime where the dimensionless ratio of radiation pressure to thermal pressure, 2I/nTc is ” 1. Conditions in this regime are found in physical conditions ranging from stellar interiors and radiation generated winds, to the formations of 'photon bubbles' in very hot stars and accretion disks and in high-energy astrophysical environments"--Pages v-vi.
