A large number of diagnostics have been used to study the performance of gas-filled, plastic-shell direct-drive implosions on the beam OMEGA laser system (Boehly T R et al Opt. Commun.   X-ray spectra are deconvolved from spectrometer measurements and simulation data generated using the GEANT4 Monte Carlo code. We also demonstrate the unique capability of laser-driven x-rays in being able to deliver single pulse high spatial .

Ceglio. X-ray crystal spectroscopy of laser produced plasmas has long been considered an important diagnostic of plasma density and temperature.(1) Absorption spectroscopy of the dense transient plasmas existing in imploding laser fusion targets has the potential of being an important avenue of fuel and shell density and temperature diagnosis.(2,3) Meaningful data, however, will require sufficient Cited by: 3.

Time- and space-resolved X-ray spectrum recorded in experiment Z This initial proof-of-principle experiment used a foam that was uniformly doped throughout its volume and a circular mm-diameter diagnostic aperture at the top of the foam.

Each frame is space-resolved along the vertical direction. The wavelength axis is horizontal. Motivated primarily by inertial confinement fusion1 and x-ray laser research,2 most studies have used nanosecond pulse gas lasers — CO2 lasers in the early days, then excimer (KrF and XeCl.

RESULTS AND DISCUSSION. Here, we use time-resolved resonant soft x-ray scattering (tr-RSXS) to study the collective dynamics of “stripe-ordered” La 2−x Ba x CuO 4 with x ∼ 1/8 (LBCO) (8, 9, 30).We use fs, eV laser pulses to drive the charge order parameter out of equilibrium and probe its subsequent dynamics by scattering fs x-ray pulses from a free-electron laser (FEL.

Velocities up to cm s−1 have been obtained in laser implosion of gold‐coated microballoons driven by irradiation at short wavelength. High‐velocity laser‐driven implosions with gold‐coated microballoons has been obtained.

Results analysis suggests that the glass shell is first decompressed by x‐ray radiation from the. Richardson's research works with 2, citations and 4, reads, including: Subnanosecond interferometry of plasma filaments in a laser-produced spark.

This imaging system aims at recording images of the core size and shape of an imploding deuterium-tritium (DT) microballoon on LMJ inertial confinement fusion (ICF) experiments.

Image acquisition is difficult due to the harsh surrounding created by the fusion reaction, which affects system specifications. This one is made of a scintillator, an optical relay, and a CCD camera shielded from the.

Hooper's 40 research works with citations and reads, including: Shifting and Merging of Ar+17 Spectral Lines Due to Electron Collision Broadening. A shock wave in fusion fuel filled in a glass microballoon target was directly observed.

The shock speed and the width of the shock front were 5×10 7 cm/s and a few μm, respectively, which are in good agreement with the shock‐tube theory. Inertial confinement fusion (ICF) is an approach to fusion that relies on the inertia of the fuel mass to provide confinement.

To achieve conditions under which inertial confinement is sufficient for efficient thermonuclear burn, a capsule (generally a spherical shell) containing thermonuclear fuel is compressed in an implosion process to conditions of high density and temperature.

One- (1D) and two-dimensional (2D) x-ray imaging techniques with x-ray streak cameras have been developed and utilized for investigating implosion dynamics of laser fusion targets.

Conventional streaked 1D images of the shell motion of the imploding target was recorded together with the time-resolved 2D multi-imaging x-ray streak images of the core shapes on the same x-ray streak camera. A detailed phenomenological study of the spectroscopic analysis of laser produced plasmas is presented in this dissertation.

High resolution x-ray spectroscopic data have been obtained in pellet implosion experiments using the 24 beam Omega laser system at the University of Rochester Laboratory for Laser Energetics.Measurements of x-ray–driven implosions with charged particles have resulted in the quantitative characterization of critical aspects of indirect-drive inertial fusion.
