Title: High-resolution observations of tungsten liner collapse and early jet formation

Abstract

High-resolution photography of collapsing tungsten-lined shaped charges has revealed surface texturing both similar to and strikingly different from that previously observed during copper liner collapse. The behavior of three types of tungsten-lined shaped charges, with different liner designs and high explosives but with similar tungsten processing, were characterized by image-converter camera and fast- framing camera photography, and flash x-ray radiography. 120-mm- diameter, trumpet-shaped Octol charges produced surface blistering near the base of the tungsten liner, probably due to inhomogeneities near the liner-explosive interface resulting from cast loading. 148- mm-diameter, quasi-conical LX-14 charges produced smooth shocked- surface texture similar to that observed in conical, copper-lined LX- 14 (Viper) charges. 81-mm-diameter, conical LX-20 charges produced severe radial texturing throughout the collapsing tungsten liner, which transitioned to azimuthal banding on the jet surface. For each type of charge, obscuring debris from the tungsten jet tip prevented clear imaging of the jet surface at late time. 8 refs., 6 figs., 2 tabs.

    Direct evidence, on an atomic scale, is presented for the enhancement of damage production per projectile ion in diatomic metallic molecular ion (dimer) irradiations of tungsten as compared to monatomic metallic ion (monomer) irradiations. Irradiations were performed in situ at less than or equal to 10 K, in a field-ion microscope, employing 20 keV Ag/sup +/ or W/sup +/ monomer ions and the results are compared with 40 keV W/sub 2//sup +/ or Ag/sub 2//sup +/ dimer ion bombardments; the average energy per ion was 20 keV. First, in the near-surface region the depleted zones produced by the W/sub 2//supmore » +/ dimer ions give rise to void-like contrast effects. The W/sup +/ monomer ions do not produce this void-like damage. The existence of voids was explained employing a nucleation and diffusion-limited growth model which suggests that the growth can occur on a time scale < 10/sup -9/s, if the effective diffusivity of an atom in the fully-developed collision cascade is > 3 x 10/sup -4/cm/sup 2/s/sup -1/. Second, by counting the number of vacancies in individual depleted zones, produced by the different ions, it was demonstrated that the number of vacancies produced per incoming ion of the dimer is 1.55 times greater than the number of vacancies produced per monomer ion.« less

    A TOW-2A 146 mm shaped charge was fired and observed with five beam Fabry-Perot laser velocimetry. The liner collapse velocities were measured at five lines of sight covering the outer half of the liner. A record of 8-10 {mu}s in length was obtained for each sight line The velocity records at late time differ for each location, reflecting the varying charge-to-mass ratio as the end of the liner is approached. The results were analyzed with the CALE-2D hydrodynamic simulation code. The calculations reproduce the jump-off times, the shapes of the velocity jumps and the late time velocity asymptotes, but theymore » underestimate the jump-off velocities by 6-7%. The calculations show that there exist no features in the velocity records that require spallation to account for them. Rather, the standard Steinberg-Guinan material model adequately accounts for the response of this copper liner to LX-14.« less

  • A normal-incidence multilayer mirror telescope was designed, fabricated, and tested. The telescope consisted of a primary mirror and a secondary mirror in a Cassegrain optical configuration. The mirrors had multilayer coatings that efficiently reflected the soft x-ray radiation in a narrow bandpass centered at a wavelength of 48 {angstrom}. The telescope was taken to the Laboratory for Laser Energetics (LLE) on October 28, 1996. The telescope was mounted in a TIM instrument module on the OMEGA target chamber. The focusing and alignment of the mirrors were checked and optimized. Images were recorded on x-ray film on October 30. Images weremore » recorded on a gated framing camera on October 31 and November 1. On each laser shot, hard x-ray images were recorded by a pinhole camera and a gated framing camera. The soft and hard x-ray images were returned to NRL for analysis. The images were digitized and compared. The major result of the study was that the soft x-ray emission from plasmas generated by 6 to 8 overlapping OMEGA beams is quite uniform, even for the case when beam smoothing techniques were not implemented. This implies that the soft x-ray emission can be used for backlighter applications and for the study of absorption by CH foils in the 48 {angstrom} wavelength region, at slightly longer wavelengths than the carbon K absorption edge where carbon is relatively transmissive. These backlighter techniques are now being implemented at LLE.« less
