Title: Design and engineering of a target for x-ray Thomson scattering measurements on matter at extreme densities and gigabar pressures

Abstract

Reconciling the experimental and system requirements during the development of a new target system is one of the most challenging tasks in the design and engineering of targets used in the National Ignition Facility. Targets for the GigaBar 3 campaign were meant to allow the detection of extremely weak Thomson scattering from matter at extreme densities in the face of very bright backlighter and laser entry hole plasma emissions. The problem was to shield the detector sufficiently while maintaining beamline and view clearances, and observing target mass restrictions. A new construction process, based on a rapid prototype frame structure, was used to develop this target. As a result, details of the design process for these targets are described, and lessons from this development for production and target assembly teams are discussed.

From microjoules to megajoules and kilobars to gigabars: Probing matter at extreme states of deformation

Journal Article Remington, Bruce A. ; Rudd, Robert E. ; Wark, Justin S. - Physics of Plasmas

Over the past 3 decades, there has been an exponential increase in work done in the newly emerging field of matter at extreme states of deformation and compression. This accelerating progress is due to the confluence of new experimental facilities, experimental techniques, theory, and simulations. Regimes of science hitherto thought out of reach in terrestrial settings are now being accessed routinely. High-pressure macroscopic states of matter are being experimentally studied on high-power lasers and pulsed power facilities, and next-generation light sources are probing the quantum response of matter at the atomic level. Combined, this gives experimental access to the propertiesmore »« less

Lightweight Target Generates Bright, Energetic X-Rays

Technical Report Hazi, A

Radiography with x rays is a long-established method to see inside objects, from human limbs to weapon parts. Livermore scientists have a continuing need for powerful x rays for such applications as backlighting, or illuminating, inertial confinement fusion (ICF) experiments and imaging still or exploding materials for the nation's Stockpile Stewardship Program. X-radiography is one of the prime diagnostics for ICF experiments because it captures the fine detail needed to determine what happens to nearly microscopic targets when they are compressed by laser light. For example, Livermore scientists participating in the National Ignition Facility's (NIF's) 18-month-long Early Light experimental campaign,more »« less

T-REX: Thomson-Radiated Extreme X-rays Moving X-Ray Science into the ''Nuclear'' Applications Space with Thompson Scattered Photons

Technical Report Barty, C P ; Hartemann, F V

The scattering of laser photons from relativistic electrons (Thomson scattering) has been demonstrated to be a viable method for the production of ultrashort-duration pulses of tunable radiation in the 10-keV to 100-keV range. Photons in this range are capable of exciting or ionizing even the most tightly bound of atomic electrons. A wide variety of atomistic scale applications are possible. For example, Thomson x-ray sources have been constructed at LLNL (PLEIADES) and LBL as picosecond, stroboscopic probes of atomic-scale dynamics and at Vanderbilt University as element-specific tools for medical radiography and radiology. While these sources have demonstrated an attractive abilitymore »« less

Observing the onset of pressure-driven K-shell delocalization

Journal Article Döppner, T. ; Bethkenhagen, M. ; Kraus, D. ; ... - Nature (London)

The gravitational pressure in many astrophysical objects exceeds one gigabar (one billion atmospheres), creating extreme conditions where the distance between nuclei approaches the size of the K shell. This close proximity modifies these tightly bound states and, above a certain pressure, drives them into a delocalized state. Both processes substantially affect the equation of state and radiation transport and, therefore, the structure and evolution of these objects. Still, our understanding of this transition is far from satisfactory and experimental data are sparse. Here, in this work, we report on experiments that create and diagnose matter at pressures exceeding three gigabarsmore »« less

Report of the National Ignition Facility Target Physics Program Review Committee

Technical Report Moses, E

The Department of Energy's (DOE) National Ignition Facility (NIF) has been under construction at the Lawrence Livermore National Laboratory (LLNL) since 1997. This multiple-beam facility is designed to be a source of powerful focused laser light pulses for experiments in support of the nuclear weapons Stockpile Stewardship Program (SSP), NIF will be operated by LLNL as national facility to elucidate high energy density science important to the weapons SSP and to achieving inertial confinement fusion (ICF) ignition. In addition, it will provide the nation with a valuable tool for exploring basic high energy density science. In September of 1999, projectedmore »« less
