Heat transfer in oscillatory flow. Progress report, January 1983-December 1983
Progress is reported in work with a water tunnel facility and wind tunnel facilities used to study heat transfer in oscillatory flow. Work on both facilities include construction and modifications of the facilities themselves, instrumentation and data acquisition, and experimental measurements. A computer code was developed for the calculation of steady and unsteady heat transfer over the attached portion of the boundary layer. The equations of momentum and energy were recast in their finite-difference form. (LEW)

Drag of heated circular cylinders
ERDA has been conducting high altitude drop tests of a heated cylinder in order to obtain aerodynamic data for use in the satellite power supply program. The cylinder simulated the cylindrical heat source for the MHW-RTG. Since drop testing is an expensive and difficult method of testing, a wind tunnel technique was developed. Results of the tests are presented. (TFD)

Drag of heated spheres
A stainless steel sphere was heated to temperatures over 1000/sup 0/F and wind tunnel tested to obtain drag data. The tests were in conjunction with ERDA's Nuclear Power Supply Satellite Program. The purpose of the tests was to provide information on the drag characteristics of the sphere while it is heated so that terminal velocities can be calculated and impact behavior of the fuel spheres predicted. Results of the tests are presented. (TFD)

Positronium reactions with diamagnetic organic molecules
From 166th American Chemical Society national meeting; Chicago, Illinois, USA (26 Aug 1973). Rate constants for the interaction of ortho- positronium atoms with a series of diamagnetic organic compounds were determined. Nitrated aromatic molecules interact far more readily with orthopositronium than do nitrated aliphatic molecules. The observed rate constants for the aromatic molecules show a distinct dependency on the nature of the subsitituents and their relative positions in the aromatic ring. This dependency may be attributed to steiic interactions which influence the relative electron charge density on the atoms in the molecule and alter the molecular energy levels. (auth)

Quantifying Silica Reactivity in Subsurface Environments: An Integrated Experimental Study of Quartz and Amorphous Silica to Establish a Baseline for Glass Durability
An immediate EM science need is a reliable kinetic model that predicts long-term waste glass performance. A framework for which the kinetics of mineral-solution reactions can be used to interpret complex silicate glass properties is required to accurately describe the current and future behavior of glasses as synthetic monoliths or natural analogs. Reaction rates and mechanisms are essential elements in deciphering mineral/material reactivity trends within a compositional series or across a matrix of complex solution compositions. An essential place to start, and the goal of this research, is to quantify the reactivity of crystalline and amorphous SiO2 phases in the complex fluids of natural systems.

24-Channel Geophone Array for Horizontal or Vertical Boreholes Quarterly Technical Report: January-March 2003
This report describes the technical progress on a project to design and construct a multichannel geophone array that improves tomographic imaging capabilities in both surface and underground mines. Especially important in the design of the array is sensor placement. One issue related to sensor placement is addressed in this report: the method for clamping the sensor once it is emplaced in the borehole. If the sensors (geophones) are not adequately coupled to the surrounding rock mass, the resulting data will be of very poor quality. Improved imaging capabilities will produce energy, environmental, and economic benefits by increasing exploration accuracy and reducing operating costs.

Managing electronic records: A guideline
A committee at Martin Marietta Energy Systems (MMES) has drafted a guideline to assist offices in the management of electronic records. This paper will address the activities surrounding its creating. The guideline is for use by creators, users, and custodians of any type of electronic information. The guideline supports and supplements requirements from DOE and the National Archives and Records Administration (NARA), other internal processes such as system reviews, and the comprehensive records management program. While an in-house publication, it could prove useful to other organizations implementing an electronic records management program.

The study of multi-institutional collaborations in high-energy physics. Progress report, January 1989--March 1991
Since World War II, the organizational framework for scientific research is increasingly the multi-institutional collaboration, especially in high-energy physics. A broad preliminary survey, into the functioning of research collaborations involving three or more institutions is described. The study is designed to identify patterns of collaborations, define the scope of the documentation problems, field-test possible solutions, recommend future actions, and build an archives of oral history interviews and other resources for scholarly use. Once the study is completed, its findings will be used to promote systems to document significant collaborative research.

LLNL Torso Phantom Assembly and Disassembly
This document from the LLNL In Vivo measurement Facility archives provides important historical as well as current methods for the proper handling of the LLNL Torso Phantom. This document was written circa 1980 and is intended for use by in vivo measurement facilities that perform calibrations using the LLNL Torso Phantom. Proper care and use of the LLNL Torso Phantom will greatly extend the useful lifetime of the phantom. The assembly, and disassembly of the Realistic Phantom are simple tasks and are, for the most part, self evident. However, there are some considerations that will make these tasks easier and assure long life of the parts. The assembly process is presented in Figures 1 through 9 while disassembly suggestions are illustrated in Figures 10 and 11.

Documenting the Physical Universe:Preserving the Record of SLAC from 1962 to 2005
Since 1905, Albert Einstein's ''miraculous year'', modern physics has advanced explosively. In 2005, the World Year of Physics, a session at the SAA Annual meeting discusses three institutional initiatives--Einstein's collected papers, an international geophysical program, and a research laboratory--to examine how physics and physicists are documented and how that documentation is being collected, preserved, and used. This paper provides a brief introduction to the research laboratory (SLAC), discusses the origins of the SLAC Archives and History Office, its present-day operations, and the present and future challenges it faces in attempting to preserve an accurate historical record of SLAC's activities.

Low-pressure approach to the formation and study of exciplex systems. [For CDC 7600]
Studies on the formation and properties of new materials for high-energy, gas-phase lasers are described. Attention is directed mainly to systems having bound excited states but unbound ground states. An important class of such excimer/exciplex systems has a van der Waals dimer/oligomer as its ground state. This research attempts to probe the relative rates of electron pumping of excited-state manifolds and the preferentially pumped vibronic states within each manifold. Reactive quenching of emission, resonant self-absorption of laser emissions, and collision- and noncollision-induced intersystem crossing are also considered. Lists of personnel and facilities are included. 8 figures, 2 tables. (RWR)

DI-TERTIABYBUTYLNITROXIDE, A HILL REAGENT
Di-tertiarybutylnitroxide (DTBN), which they have tried to use as a trapping agent to identify the species giving rise to the photo-induced EPR signals in photosynthetic materials, functions as a Hill reagent with spinach chloroplasts. Evidence is presented which indicates that the reduction of DTBN is affected by photosystem II of the electron transport system of spinach chloroplasts. The reduced form of DTBN, the hydroxylamine, undergoes a photo-oxidation with spinach chloroplasts. Possible explanations of this apparent inconsistency are presented. A product which could be ascribed to a chemical coupling reaction between the nitroxide and the radical species giving rise to the photo-induced EPR signals in spinach chloroplasts was not detected, even using radioactive tracer methods.

BTA Magnet Field Map Archive and MAD Model
This note publishes some and information that has resided in private files. The attached tables were provided by Joseph Skelly from his archives. They show magnetic field measurements versus excitation current for the Booster to AGS transfer line quadrupoles and dipoles based on field measurements [we believe] were done by the Magnet Division. Also given are Ed Blesser's fifth order fits of field versus current. The results are given in 'Tesla' or T-M/M. These tables are attached to provide an archive of this data. The MAD model of the BTA line does have the same values as shown in the attached fits so the transfer was correct. MAD uses as its 'gradient' for quads Tesla per meter normalized to rigidity [B-rho]. The model of the BTA line in use uses the T-M/M given in the tables divided by the length to give T M which is then normalized by Brho. Thus, the input to the model appears to be correct. The original model is also attached as part of a memo by Skelly describing it.
