Pion Resonances in π⁻-p Interactions at 4.65 Bev/c (open access)

Pion Resonances in π⁻-p Interactions at 4.65 Bev/c

This note describes some results of the study of single pion production in π⁻-p interactions at 4.65 Bev/c, using the BNL 20" Hydrogen Bubble Chamber. It is well known that the observability of some of the particle resonances (e.g. 33 Isobar and η) varies markedly with the energy of the incident particle. The ρ meson has been observed in π⁻-p interactions at 1.25 Bev/c and 1.9 Bev/c incident pion energies. Evidence will be shown that this resonance persists with the much higher incident pion energy used in the present experiment.

Code Listings for the Floss III - Compatible Programs Including Floss Type 3 and Type 12, Nomac, and Dash N (open access)

Code Listings for the Floss III - Compatible Programs Including Floss Type 3 and Type 12, Nomac, and Dash N

FLOSS III is a third-generation version of a digital computer program which solves a one-dimensional difference representation of the momentum, energy, continuity, and state equations for turbulent, compressible gas flow in equivalent hydraulic channels. Extensive use of this program has been employed in the design and performance analyses of Pluto-type nuclear heat exchangers, and in the specific case of the Tory II-A test series, agreement was obtained to better than 5% for all experimentally measured parameters. The NOMAC and DASH-N programs combine the effects of up to thirty varieties of channels with the dependent boundary conditions imposed by a common inlet diffuser and exit nozzle. The resulting calculations yield performance information for blow-down facility and ramjet flight condition application of the heat exchanger.

Weldability Tests of Four High Strength Structural Steels (open access)

Weldability Tests of Four High Strength Structural Steels

Three proprietary high strength, low alloy steels and a high strength alloy steel were welded without a pre or post heat treatment with low hydrogen, iron powder coated electrodes of appropriate physical properties. Tensile and bend tests performed upon sample weldments indicated that they exhibited properties very similar to those for the base plate and that there were no indications of brittleness, notch sensitivity, underbead cracking, lack of fusion, hot cracking, undercutting, or crater cracking.

Radiation damage at the Rotating Target Neutron Source (RTNS-I) facility at Lawrence Livermore Laboratory (open access)

Radiation damage at the Rotating Target Neutron Source (RTNS-I) facility at Lawrence Livermore Laboratory

Some of the basic computational features of a computer program used for modeling radiation damage at LLL's Rotating Target Neutron Source (RTNS-I) are presented. Input items required are material cross-section and angular distribution data, such as used for LLL neutron transport calculations, along with one particular neutron spectrum of interest. The nuclear reactions considered are elastic, neutron-emitting, and charged-particle-emitting. Classical and relativistic mechanics are used as required to calculate the resulting primary-recoil energy spectra and damage energy spectra. Calculative results are presented for the RTNS-I neutron spectra on aluminum, titanium, vanadium, iron, nickel, copper, zirconium, niobium, molybdenum, silver, tin, tantalum, tungsten, gold, and lead. 63 figures.

Weinberg--Salam gauge model and neutrino proton elastic scattering. [Differential cross sections] (open access)

Weinberg--Salam gauge model and neutrino proton elastic scattering. [Differential cross sections]

Elastic scattering of neutrino on proton is studied in the Weinberg-Salam gauge model of neutral currents. Particular attention is paid to the experimental cuts relevant to two recent BNL experiments and spectra averaging so that model predictions can be directly compared to the experimental data. The uncertainty in the calculation due to changes in the parameters which are not well determined such as the mass of the axial vector meson is emphasized. It is concluded that the simple Weinberg-Salam gauge model with sin/sup 2/ theta/sub W/ approximately 0.4 is consistent with the recent measurement of R/sub el/sup nu/ = less than sigma( (nu + p ..-->.. nu + p) greater than/less than sigma(nu + n ..-->.. ..mu../sup -/ + p) greater than provided M/sub A/ approximately 1.15 GeV which is within the range of uncertainty of this parameter. Similar calculation for the case of antineutrino proton elastic scattering, i.e., R/sub el/sub 3//sup anti nu/ = less than sigma (anti nu + p ..-->.. anti nu + p) greater than/less than sigma (anti nu + p ..-->.. ..mu../sup +/ + n) greater than is presented.

Low-cost silicon solar array project. First annual report, January 1975--March 1976 (open access)

Low-cost silicon solar array project. First annual report, January 1975--March 1976

The Low-Cost Silicon Solar Array Project (LSSA) was established to greatly reduce the price of solar arrays by the improvement of manufacturing technology, by adaptation of mass production techniques, and by helping achievement of user acceptance. The Project's approach includes the development of technology, its transfer by industry to commercial practice, the evaluation of the economics involved, and the stimulation of market growth. The activities and progress of the LSSA Project during its first year are described in this document which covers all Project activities, with primary emphasis on the technical plans and accomplishments. The development of manufacturing technology is now and will continue to be performed principally by industries and universities. To date, 24 contractors are working on new silicon-refinement processes, silicon-sheet-growth techniques, encapsulants, and automated-assembly studies. Nine more contractors have been selected to perform additional technology investigations and their contracts are being negotiated. Additional contracts will be issued in the future as promising ideas appear. (WDM)

New Crystalline Materials for Nonlinear Frequency Conversion, Electro-Optic Modulation, and Mid-Infrared Gain Media (open access)

New Crystalline Materials for Nonlinear Frequency Conversion, Electro-Optic Modulation, and Mid-Infrared Gain Media

New crystalline materials were investigated for applications in frequency conversion of near-infrared wavelengths and as gain media for tunable mid-infrared solid-state lasers. GaCa{sub 4}O(BO{sub 3}){sub 3} (GdCOB), YCa{sub 4}O(BO{sub 3}){sub 3} (YCOB), LaCa{sub 4}O(BO{sub 3}){sub 3} (LaCOB), and Gd{sub 0.275}Y{sub 0.725}Ca{sub 4}O(BO{sub 3}){sub 3} were characterized for frequency conversion of 1 {micro}m lasers. For type I doubling at 1064 nm, LaCOB, GdCOB, and YCOB were found to have effective coupling coefficients (d{sub eff}) of 0.52 {+-} 0.05, 0.78 {+-} 0.06, and 1.12 {+-} 0.07 pm/V, respectively. LaCOB was measured to have angular and thermal sensitivities of 1224 {+-} 184 (cm-rad){sup -1} and < 0.10 (cm-{sup o}C){sup -1}, respectively. The effective coupling coefficient for type II noncritically phasematched (NCPM) doubling at 1064 nm in Gd{sub 0.275}Y{sub 0.725}Ca{sub 4}O(BO{sub 3}){sub 3} was measured to be 0.37 {+-} 0.04 pm/V. We predict LaCOB to have a type I NCPM fundamental wavelength of 1042 {+-} 1.5 nm. Due to its low angular and thermal sensitivities for doubling near 1047 nm, LaCOB has potential for frequency doubling of high-average power Nd:LiYF{sub 4} and Yb:Sr{sub 5}(P0{sub 4}){sub 3}F lasers. LaCOB, GdCOB, and YCOB were also investigated for optical parametric oscillator applications and we determined that they …

Determination of the compatibility between structural alloys and molten metals at high temperatures (open access)

Determination of the compatibility between structural alloys and molten metals at high temperatures

The experimental methods for determining high-temperature compatibility between structural alloys and molten metals, particularly braze alloys, have been established. The structural alloys of interest are formed or machined into small crucibles into which the metal to be melted is placed. This system is placed in a furnace which typically will have a vacuum or inert gas environment; other atmospheres are possible as well. Multiple crucibles are exposed for various times and temperatures. Following cooling, a visual examination for loss of containment is performed. Each crucible is then sectioned and examined metallographically to document any loss in thickness of the crucible or any reactions between the materials. These procedures are fairly simple and require only common laboratory equipment; costs, therefore, are kept low. These experimental techniques were refined for use in determining the compatibility of both commercially pure vanadium and 21-6-9 stainless steel with a 92.5% Pb-5% In-2.5% Ag braze alloy. Both the vanadium and the stainless steel contained the molten Pb-In-Ag alloy for exposures ranging from 1000C for 10 minutes up to 1200C for 2 hours.

A conceptual design for the STAR endcap electromagnetic calorimeter (open access)

A conceptual design for the STAR endcap electromagnetic calorimeter

In order to make measurements of the gluon spin or helicity distribution in the proton or the gluon spin average distribution in nuclei, both a barrel and an endcap electromagnetic calorimeter must be added to the STAR baseline detector. Information on the gluon will be obtained in inclusive direct-{gamma} + jet and jet + jet production. In order to be sensitive to the proper gluon kinematic regions, either the direct-{gamma} or the jet must be in the endcap electromagnetic calorimeter (EMC). However, the endcap EMC is not large enough to completely contain the jets, so that the barrel EMC is also needed. This note describes a conceptual design for the STAR endcap EMC. Constraints are imposed by the space available between the end of the time projection chamber (TPC) and the inside of the magnet pole tip iron. Severe constraints also occur near {vert_bar}{eta}{vert_bar} = 1, where the barrel and endcap EMC`s meet. Cables from detectors inside the EMC, including those from the TPC, will exit from STAR near {vert_bar}{eta}{vert_bar} = 1. The constraints in this region have not yet been seriously studied since no decision on the detailed routing of these cables was available at the time this work …

Excess plutonium disposition: The deep borehole option (open access)

Excess plutonium disposition: The deep borehole option

This report reviews the current status of technologies required for the disposition of plutonium in Very Deep Holes (VDH). It is in response to a recent National Academy of Sciences (NAS) report which addressed the management of excess weapons plutonium and recommended three approaches to the ultimate disposition of excess plutonium: (1) fabrication and use as a fuel in existing or modified reactors in a once-through cycle, (2) vitrification with high-level radioactive waste for repository disposition, (3) burial in deep boreholes. As indicated in the NAS report, substantial effort would be required to address the broad range of issues related to deep bore-hole emplacement. Subjects reviewed in this report include geology and hydrology, design and engineering, safety and licensing, policy decisions that can impact the viability of the concept, and applicable international programs. Key technical areas that would require attention should decisions be made to further develop the borehole emplacement option are identified.

An external peer review of the U.S. Department of Energy`s assessment of ``damages and benefits of the fuel cycles: Estimation methods, impacts, and values``. Final report (open access)

An external peer review of the U.S. Department of Energy`s assessment of ``damages and benefits of the fuel cycles: Estimation methods, impacts, and values``. Final report

The need for better assessments of the ``external`` benefits and costs of environmental effects of various fuel cycles was identified during the development of the National Energy Strategy. The growing importance of this issue was emphasized by US Department of Energy (DOE) management because over half of the states were already pursuing some form of social costing in electricity regulation and a well-established technical basis for such decisions was lacking. This issue was identified as a major area of controversy--both scientifically and politically--in developing energy policies at the state and national level. In 1989, the DOE`s Office of Domestic and International Energy Policy commissioned a study of the external environmental damages and benefits of the major fuel cycles involved in electric power generation. Over the next 3-year period, Oak Ridge National Laboratory and Resources for the Future conducted the study and produced a series of documents (fuel cycle documents) evaluating the costs of environmental damages of the coal, oil, natural gas, biomass, hydroelectric, and nuclear fuel cycles, as well as the Background Document on methodological issues. These documents described work that took almost 3 years and $2.5 million to complete and whose implications could be far reaching. In 1992, the …
