Title: Demonstration of a Long Pulse X-ray Source at the National Ignition Facility

Abstract

A long duration high fluence x-ray source has been developed at the National Ignition Facility (NIF). The target was a 14.4 mm tall, 4.1 mm diameter, epoxy walled, gas filled pipe. Approximately 1.34 MJ from the NIF laser was used to heat the mixture of (55:45) Kr:Xe at 1.2 atm (~5.59 mg/cm³) to emit in a fairly isotropic radiant intensity of 400–600 GW/sr from the E_photon = 3–7 keV spectral range for a duration of ≈ 14 ns. Lastly, the HYDRA simulated radiant intensities were in reasonable agreement with experiments but deviated at late times.

Investigation of high X-ray conversion efficiency Kr filled gas sources at the National Ignition Facility

Journal Article May, M. J. ; Kemp, G. E. ; Colvin, J. D. ; ... - Physics of Plasmas

In this work, we report on the performance of high x-ray fluence Kr K-shell sources that are being developed for high energy density experiments. These targets are 4.1 mm in diameter 4.4 mm tall hollow epoxy tubes having a 40 μm thick wall holding 1.5 atm of Kr gas. For these shots, the National Ignition Facility laser delivered a nominally constant total energy of ≈750 kJ of 351 nm (3ω) light at the three power levels [e.g., ≈120 (low), ≈145 (medium), and ≈210 TW (high)].

Bright x-ray stainless steel K-shell source development at the National Ignition Facility

Journal Article May, M. J. ; Fournier, K. B. ; Colvin, J. D. ; ... - Physics of Plasmas

High x-ray conversion efficiency (XRCE) K-shell sources are being developed for high energy density experiments for use as backlighters and for the testing of materials exposed to high x-ray fluxes and fluences. Recently, sources with high XRCE in the K-shell x-ray energy range of iron and nickel were investigated at the National Ignition Facility (NIF). The x-ray conversion efficiency in the 5–9 keV spectral range was determined to be 6.8% ± 0.3%. These targets were 4.1 mm diameter, 4 mm tall hollow epoxy tubes having a 50 μm thick wall supporting a tube of 3 to 3.5 μm thick stainless steel. The NIF laser deposited ∼460 kJ ofmore »« less

Foot-pulse radiation drive necessary for ICF ignition capsule demonstrated on Z generator

Conference Sanford, T W.L. ; Olson, R E ; Chandler, G A

Implosion and ignition of an indirectly-driven ICF capsule operating near a Fermi-degenerate isentrope requires initial Planckian-radiation-drive temperatures of 70-to-90 eV to be present for a duration of 10-to-15 ns prior to the main drive pulse. Such capsules are being designed for high pulsed-power generators. This foot-pulse drive capability has been recently demonstrated in a NIF-sized ({phi} = 6-mm 1 = 7-mm), gold hohlraum, using a one-sided static-wall hohlraum geometry on the Z generator. The general arrangement utilized nested tungsten-wire arrays of radii (mass) 20 mm (2 mg) and 10 mm (1 mg) that had an axial length of {approximately} 10more »« less
Laser Beam Propagation through Long Ignition Scale Plasmas on NIF

Conference Glenzer, S H

Experiments on the National Ignition Facility (NIF) have employed the first four beams to measure propagation and laser backscattering losses in large ignition-size plasmas. Gas-filled targets between 2 mm and 7 mm length have been heated from one side by overlapping the focal spots of the four beams from one quad operated at 351 nm (3{omega}) with a total intensity of 2 x 10{sup 15}W cm{sup -2}. The targets were filled with 1 atm of CO{sub 2} producing of up to 7 mm long homogeneously heated plasmas with densities of n{sub e} = 5 x 10{sup 20} cm{sup -3} andmore »« less
