S-11 and S-20 photocathode research activity. Rev. 1

Description: The S-1 semi-transparent photocathode is the only one that can be used to study the 1.06 ..mu..m neodynium laser pulses of less than 10 ps duration. We first reviewed the recent results obtained at the Paris Observatory (research sponsored by the CEA), and then we tried to determine the role of the main constituents and their contributions in photoemission.

ATA gas propagation - 1 foot tank experiment

Description: The first gas propagation experiment on ATA is planned to be conducted in a 1-foot diameter tank of up to 10 m length. The primary objectives are to measure beam parameters at injection to determine whether the desired beam conditioning is achieved, and to observe how such conditioned beams propagate in air and neon.

Compensation for Crime Victims

Description: This report discusses the growing interest in recent years in providing compensation for the innocent victims of violent crime through programs financed by the Federal and/or State Governments. At issue have been the general propriety, desirability, and feasibility, as well as the cost, of Federal support of such programs.

Concentration of radionuclides in fresh water fish downstream of Rancho Seco Nuclear Generating Plant

Description: Fish were collected for radionuclide analysis over a 5-month period in 1984 from creeks downstream of the Rancho Seco Nuclear Generating Plant, which has been discharging quantities of some fission and activation products to the waterway since 1981. Among the fish, the bluegill was selected for intensive study because it is very territorial and the radionuclide concentrations detected should be representative of the levels in the local environment at the downstream locations sampled. Among the … more

Effects of core mixing on solar oscillation frequencies

Description: This paper discusses predicted p- and g-mode periods for two solar models provided by Schatzman and Maeder (1981). One model has no mixing while the other has turbulent diffusion mixing (allowed for by a Reynolds number of 100). The resulting g-mode period spacings allow a very close look at the central solar structure which, like the p-mode period splittings, indicate little or no mixing over the lifetime of the sun.

Fractional Quantization of the Hall Effect

Description: The Fractional Quantum Hall Effect is caused by the condensation of a two-dimensional electron gas in a strong magnetic field into a new type of macroscopic ground state, the elementary excitations of which are fermions of charge 1/m, where m is an odd integer. A mathematical description is presented.

Simulation of shock-induced energy flux in molecular solids. Revision 1

Description: Computer molecular dynamics has been used to study the time evolution of the energy of diatomic molecules embedded in a monatomic host lattice when the system is shock loaded. Center-of-mass, rotational, and internal energies were each monitored. For H/sub 2/ and CH groups in an iron host, the results demonstrate rapid and violent internal excitation of a totally athermal nature. The origins of this are discussed as are the reasons for the absence of a similar effect for a CH group in a carbon … more

Sodium technology activities at HEDL in support of fast reactor development and the FFTF

Description: Activities of the Hanford Engineering Development Laboratory are presented. A brief description of FFTF and some highlights of reactor operations are reviewed. The sodium technology work at HEDL is summarized by discussing several facets of the program and their tie-ins to breeder reactor development.

Use of the ORACLE DBMS in determining the response of complex scientific instrumentation

Description: In the Laser Fusion Program at Lawrence Livermore National Laboratory, a single laser fusion experiment lasts only a billionth of a second but in this time high speed instrumentation collects data that when digitized will create a data bank of several megabytes. This first level of data must be processed in several stages to put it in a form useful for interpretation of the experiments. One stage involves unfolding the source characteristics from the data and response of the instrument. This in… more

Wildlife Impact Assessment and Summary of Previous Mitigation Related to Hydroelectric Projects in Montana, Phase I, Volume Two (A), Clark Fork Projects, Thompson Falls Dam, Operator, Montana Power Company.

Description: The Thompson Falls Dam inundated approximately 347 acres of wildlife habitat that likely included conifer forests, deciduous bottoms, mixed conifer-deciduous forests and grassland/hay meadows. Additionally, at least one island, and several gravel bars were inundated when the river was transformed into a reservoir. The loss of riparian and riverine habitat adversely affected the diverse wildlife community inhabiting the lower Clark Fork River area. Quantitative loss estimates were determined for… more
