Analysis of owner design specifications for snubbers. Report 2 (open access)

Analysis of owner design specifications for snubbers. Report 2

The report discusses and evaluates the adequacy of buyer specifications for snubbers. Technical specifications for snubbers (hydraulic and mechanical) were studied in detail in an effort to define the ''fundamental needs'' of the industry with respect to characteristics of snubbers during operation. In the course of this study, it was determined that there is insufficient consensus among users to make such a definition. Authorities in the fields of structural dynamics, structural systems design, and snubber design were also consulted for additional information. Information from these sources is incorporated to identify the fundamental areas of concern, areas where consensus is lacking, and problems to be resolved in order to establish meaningful standards for this equipment.

Cost-Benefit Analysis of Advanced, Sanitary Sewage Treatment at Rocky Flats (open access)

Cost-Benefit Analysis of Advanced, Sanitary Sewage Treatment at Rocky Flats

A small, secondary treatment plant for processing sanitary wastes was upgraded by the addition of tertiary treatment (chemical treatment and final clarification) and mixed-media filtration. Operational data showed that the tertiary treatment significantly reduced pollutants. Filtration further reduced suspended solids significantly and removed some additional phosphorus; however, no additional reduction in total oxygen demand or in nitrogen was noted. Detailed analyses of costs for construction and routine operations showed the cost of tertiary treatment was small compared to costs associated with mixed-media filtration.

Detection and measurement of Post-Rosenbluth convective instability in MFTF with a hybrid CO/sub 2/ laser--heterodyne diagnostic system (open access)

Detection and measurement of Post-Rosenbluth convective instability in MFTF with a hybrid CO/sub 2/ laser--heterodyne diagnostic system

To measure and classify the Post-Rosenbluth convective loss-cone instability in MFTF, we propose to use a CO/sub 2/ laser consisting of a TEA-pulsed section and a low pressure CW section, together with a light mixing receiver. Calculations show that this system offers sufficient power and sensitivity to detect instability throughout the range from strong coherent light scattering to weak incoherent scattering when the instability is eliminated.

Development of mullite substrates and containers. Silicon sheet growth development for the Large Area Silicon Sheet Task of the Low-Cost Silicon Solar array Project. Quarterly report No. 1, October 6, 1977--November 14, 1977

Eight mullite bodies of varied compositions and microstructures have been prepared and are being characterized. These compositions will be submersed in molten silicon to study the impurity and surface effects. These various mullite materials will be analyzed for use as substrates for Honeywell Contract No. 954356, silicon on ceramic program and for use as a container of molten silicon. Low cost processing methods are being developed and evaluated for manufacturing large mullite sheets and mullite containers. At present, a state-of-the-art roll compaction process has shown promising initial results for substrates. However, these 0.5mm x 10cm x 1m are extremely fragile. Slip casting or iso pressing are anticipated for containers.

EPMT: a portable transfer standard for telemetry system pressure-transducer calibration

The LLL developed electronic pressure meter (EPMT) is a portable static-pressure calibration instrument for use with the LLL telemetry transducer system at the Nevada Test Site (NTS). It is significantly more accurate and rugged than the bourdon-tube pressure gauge it replaces, and can be incorporated into a field-use, semi-automatic, pressure calibration system. The process by which a transducer is selected for EPMT use from the inventory of field-service-certified transducers and subjected to an extensive preconditioning and calibration procedure is described. By combining this unusual calibration procedure with a unique, statistically based data-reduction routine, the total uncertainty of the measuring process at each calibration point can be determined with high accuracy.

Evaluation of the hazard associated with fabricating beryllium copper alloys (open access)

Evaluation of the hazard associated with fabricating beryllium copper alloys

Beryllium-copper alloys should be considered toxic materials and proper controls must be used when they are machined, heated, or otherwise fabricated. Air samples should be taken for each type of fabrication to determine the worker's exposure and the effectiveness of the controls in use. It has been shown that aerosols containing beryllium are generated during the four methods of fabrication tested, and that these aerosols can be reduced through local exhaust to undetectable levels. Considering the acute, chronic and possibly carcinogenic effects of exposure to beryllium, effective controls should be required because they are feasible both technologically and economically. The health hazards and control measures are reviewed.

Field Theories in Terms of Particle-String Variables: Spin, Internal Symmetries and Arbitrary Dimension

Essential tools are provided for a program of rewriting field theories in terms of particle-string variables. The general methods are illustrated in the case of quantum chromodynamics: (1) One finds the particle-trajectoy representation for the quark Green's functional. (2) One derives directly correct end-point terms for quarks at the ends of strings. (1) and (2) are for any number of dimensions. (3) In two dimensions, one finds a functional bridge from quantum chromodynamics to the Bardeen-Bars-Hanson-Peccei string.

ISABELLE, accumulators, bunched beams and cosmictrons (open access)

ISABELLE, accumulators, bunched beams and cosmictrons

An elaboration of the ISABELLE concept as the model for a high energy, high luminosity proton-proton facility is given. Its place in the total high energy physics program is discussed. Certain features of the ISABELLE design which have not been consolidated, in particular injection and modes of beam operation, are considered. A new scheme is reviewed, one which could provide quick beam turn-on after construction, one in which there is a high probability of reaching and perhaps even exceeding the design objectives, one which should provide comparatively more flexible and reliable operation for physics, and finally one whose presence opens up a window to a much higher energy region. The new system involves the use of a physically separate current accumulator, allowing, therefore, the optimal utilization of the superconducting structures. The fact that an obvious addition to the complex will permit pp collisions in the 4 TeV center-of-mass energy region, which corresponds to an equivalent lab energy of approximately 10/sup 16/ eV, i.e., cosmic ray energies, prompts the added structure to be referred to as the COSMICTRON. The facility operated in the ''new'' manner proposed is considered to be ''the best ISABELLE that can be built.''

Modification of the combined FI/EI ion source to permit operation in the FD mode is underway. Oxidation-reduction and activation cells were fabricated and assembly of the vacuum system for the activation cell is in progress. High- and low-voltage power supplies needed for emitter preparation were constructed. The sensitivity for field ionization of decane relative to that for ethylbenzene was measured as a function of binary mixture composition, ion-source temperature, and field strength. A gallium frit is being added to the all-glass inlet system. The purity of 25 saturates and naphthenes and 10 single-ring aromatics substituted with alkyl groups was checked using FID/GC.

Nickel--chromium strain gages for cryogenic stress analysis of superconducting structures in high magnetic fields (open access)

Nickel--chromium strain gages for cryogenic stress analysis of superconducting structures in high magnetic fields

Evaluation and calibration measurements were performed on commercial nickel-chromium metal-foil strain gages in a high-magnetic-field (12 T), liquid-helium (4.2 K) environment. The purpose was to fully characterize strain gages for use at cryogenic temperatures in high magnetic fields. In this study, the magnetoresistance of a number of strain gages was measured in three orthogonal directions at mechanical strain levels to 8900 ..mu..m/m. As a result, a unique calibration curve was defined for magnetoresistance strain errors that is independent of strain level and field direction to 12 T at 4.2 K. A current strain-gage application is the measurement of superconductor mechanical properties. These gages will soon be used in the stress analysis of superconducting fusion magnets during cooldown from ambient temperatures and during operation at 4.2 K with magnetic fields to 12 T.

Preliminary report on retardation factors and radionuclide migration

Available data on distribution coefficients for the biologically important radionuclides present in high-level waste were used to estimate retardation factors (K/sub f/) for a mass transport hydrologic model. The radionuclides were divided into 3 groups: fission products with no sorption (K/sub f/ = 1), fission products with sorption (K/sub f/ = 10/sup 2/), and the actinides and their daughter products (K/sub f/ = 10/sup 4/). Minimum and maximum values were assigned the latter two groups. Uncertainties as a function of time were estimated at +- an order of magnitude. 39 references, 5 tables.

Solar and geothermal energy utilization n SF-2: a sensitivity analysis

A sensitivity analysis was conducted of the utilization levels for Solar, Geothermal, and Advanced Energy Systems (ASGA) technologies during the 1985-2000 time period. In particular, the sensitivity of the utilization levels was tested with respet to both analytical techniques and to specific parameter assumptions. The sensitivity to analytical techniques was examined insofar as certain criteria were examined to elucidate their importance in determining the level of use of the ASGA technologies. The criteria incorporated consideration of such factors as total cost of the energy system, environmental impacts, and resource use patterns. The parameter assumptions studied included costs of ASGA costs of ASGA technologies, costs of non-renewable resources, and limitations on the use of technologies and resources. (MHR)

Strain-critical current data for large multifilament Nb/sub 3/Sn conductors

Strain-critical current measurements of monolithic, multifilament Nb/sub 3/Sn conductors are extended to larger conductors carrying approximately 3.5 kA at 12 T. Measurements were made under pure tension up to 0.9 percent strain and under combined tensile (up to 0.36 percent) and bending (+-0.53 percent) strain. Our results came close to those obtained previously on smaller (1 to 2 kA) conductors. These latest data served as our basis to design a prototype 5-kA, 12-T conductor for a 40-cm-bore magnet.

Theoretical studies involving candidate VIA laser systems

Theoretical studies supporting the Livermore photolytic Group VIA laser project were initiated early in 1977. Results of numerous theoretical studies which deal with the photolysis process, losses in the upper laser level and the photolytic pumps are described. Results of ab initio calculations on OCS have been used to assign the electronic states and to analyze the photolysis process. Photoionization cross sections of the upper laser level have been calculated for O(/sup 1/S), S(/sup 1/S) and Se(/sup 1/S). Potential curves of S/sub 2//sup +/ have been determined in the search for possible quenching processes of the upper state. Besides determining ab initio potential energy curves of rare-gas excimer pumps we have also determined photoionization cross sections of the excimer states.
