Integrated simulation of the generation and transport of proton beams from laser-target interaction
High current, energetic protons are produced by irradiating thin metal foils with intense lasers. Here, the laser plasma interaction produces relativistic electrons at the critical surface. TheseExpand

Pulsed-power-driven cylindrical liner implosions of laser preheated fuel magnetized with an axial field
The radial convergence required to reach fusion conditions is considerably higher for cylindrical than for spherical implosions since the volume is proportional to r2 versus r3, respectively. FuelExpand

Architecture of petawatt-class z-pinch accelerators.
We have developed an accelerator architecture that can serve as the basis of the design of petawatt-class z-pinch drivers. The architecture has been applied to the design of two z-pinch accelerators,Expand

Conceptual designs of two petawatt-class pulsed-power accelerators for high-energy-density-physics experiments
Here, we have developed conceptual designs of two petawatt-class pulsed-power accelerators: Z 300 and Z 800. The designs are based on an accelerator architecture that is founded on two concepts:Expand

Study of X-ray photoionized Fe plasma and comparisons with astrophysical modeling codes
Abstract The charge state distributions of Fe, Na and F are determined in a photoionized laboratory plasma using high-resolution X-ray spectroscopy. Independent measurements of the density andExpand

Filtered x-ray diode diagnostics fielded on the Z accelerator for source power measurements
Filtered x-ray diode (XRD) detectors are used as primary radiation flux diagnostics on Sandia’s Z accelerator, which generates nominally a 200-TW, 2-MJ, x-ray pulse. Given such flux levels and XRDExpand

Characteristics and scaling of tungsten-wire-array z -pinch implosion dynamics at 20 MA.
We present observations for 20-MA wire-array z pinches of an extended wire ablation period of 57%+/-3% of the stagnation time of the array and non-thin-shell implosion trajectories. These experimentsExpand

Measurements of magneto-Rayleigh–Taylor instability growth during the implosion of initially solid metal liners a)
A recent publication [D. B. Sinars et al., Phys. Rev. Lett. 105, 185001 (2010)] describes the first controlled experiments measuring the growth of the magneto-Rayleigh–Taylor instability in fastExpand

Simulations of the implosion and stagnation of compact wire arrays
Wire array z-pinches have been used successfully for many years as a powerful x-ray source, as a dynamic hohlraum, and as an intense K-shell radiation source. Significant progress has been made inExpand
