Large-area sheet task advanced dendritic web growth development. Quarterly report, October 23, 1983-December 31, 1983 (open access)

Large-area sheet task advanced dendritic web growth development. Quarterly report, October 23, 1983-December 31, 1983

Two types of design concepts were evaluated with the thermal models: (1) a vertical thermal element which modifies both the temperature profile in the web as well as the convective gas flow near the web; and (2) a thinner lid configuration in which the second lid is replaced by a hot cavity. Each involves trade-offs which need experimental evaluation. Residual stress measurements using the serial split-width technique indicated that the real residual stress was comparable to (or less than) the equivalent residual stress, which has been used as a measure of structural perfection in web crystals in previous reports. New dynamic and new static configurations were given preliminary evaluation in the laboratory, with results generally in agreement with the made predictions. Improved system temperature measurements were made leading to growth in closer agreement with the model predictions. Improved methods for controlling convective gas flow and oxide deposition were developed.

Edge blurring in stacked x-ray film screen combinations. [Flash radiography for nuclear weapons design] (open access)

Edge blurring in stacked x-ray film screen combinations. [Flash radiography for nuclear weapons design]

The Advanced Experiments Group of B-Division, LLNL, has been seeking to improve the sensitivity and spatial resolution of stacked film screens for bremsstrahlung flash radiography of imploding, dense metal shells. In the work reported here, we experimentally measured the spreading of the x-ray shadow of the edge of a uranium block in two film-and-screen combinations. We also used the SANDYL code, which models photon and electron scattering, to calculate the theoretical edge spreading in an array of films and screens. Experimentally, the uranium edge was spread to a width of 1.7 mm in the combination 0.15-mm-Ta/NDT9-XAR5, and 1.5 mm in the combination 0.25-mm-Ta/NDT6-XAR5. The theoretical calculation agreed with these results.
