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.

Alternating gradient synchrotron (open access)

Alternating gradient synchrotron

With the start of a research and development effort directed towards the Superconducting Super Collider (SSC), it is essential that US industry become involved as soon as possible. For that reason, I describe what a conventional accelerator complex is like and therefore what the first stages of the SSC would entail.

Multivent effects in a large scale boiling water reactor pressure suppression system (open access)

Multivent effects in a large scale boiling water reactor pressure suppression system

The steam-driven GKSS pressure suppression test facility, which contains 3 full scale vent pipes, has been used for 5 years to investigate the postulated loss-of-coolant accident in a Mark II and Type 69 boiling water reactor. Using the results from several of these tests, wetwell boundary load data (peak pressures and spectral power) during the chugging stage, have been evaluated for sparse pool response (one and two vents in the three vent pool) and for full pool response (one, two, or three vent operation in pools of constant wetwell pool area per vent). The sparse pool results indicate the pool-system, chug event boundary loads are strongly dependent on wetwell pool area per vent, with the load increasing with decreasing area. The full pool results show a substantial increase in the pool-system, chug event boundary loads upon a change from single cell to double cell operation; only minor change occurs in going from double to triple cell operation.

Longitudinal bunching of electrons in the Advanced Test Accelerator (open access)

Longitudinal bunching of electrons in the Advanced Test Accelerator

The Advanced Test Accelerator (ATA) is a linear induction accelerator for electrons with design goals of 50 MeV and 10 kA. The accelerator consists of a 2.5 to 3 MeV injector and 170 accelerating units, each unit capable of an applied voltage up to 350 kV. At a number of positions in the accelerator, the return current in the beam pipe is measured as a function of time as the beam passes that position. The measuring device, a four quadrant addition, is somewhat sensitive to the transverse position of the beam centroid as well as transverse distribution of current in the beam. Therefore a time-dependent signal may indicate time-dependent transverse motion or beam structure as well as an axial modulation of the beam current. These signals sometimes exhibit spikes and notches on the leading and trailing edges of the beam pulse. The presence of these rapidly varying signals during the rise and fall of the current stimulated this work. 2 references, 4 figures.

Progress in Inertial Confinement Fusion at Lawrence Livermore National Laboratory (open access)

Progress in Inertial Confinement Fusion at Lawrence Livermore National Laboratory

The goals of the Inertial Fusion Program at the Lawrence Livermore National Laboratory are to study matter under extreme conditions of temperature and pressure and to produce fusion energy from inertially confined fusion fuel. With the conclusion of recent multi-kilojoule 0.53 ..mu..m experiments on Novette, we have demonstrated vastly improved plasma conditions compared to those previously obtained at LLNL with similar energies at 1.06 ..mu..m and elsewhere with 10 ..mu..m radiation. The lower preheat environment obtainable with short wavelength light has led to 3X improvements in the compression of targets on Novette compared to similar targets on Shiva with 1.06 ..mu..m. Subsequent experiments on Nova with short wavelength light will begin in 1985. They are expected to demonstrate the necessary compression conditions required for high gain fusion to occur when irradiated with a multi-megajoule driver. These recent results, together with improved calculations, and innovations in driver and reactor technology, indicate that high gain inertial fusion will occur and is a viable candidate for fusion power production in the future.
