Investigation of diamond turning on beryllium was made in anticipation of obtaining an optical finish. Although results of past experiences were poor, it was decided to continue diamond turning on beryllium beyond initial failures. By changing speed and using coolant, partial success was achieved. Tool wear was the major problem. Tests were made to establish and plot wear as a function of cutting speed and time. Slower speeds did cause lower wear rates, but at no time did wear reach an acceptable level. The machine, tools, and procedure used were chosen based on the results of preliminary attempts and on previous experience. It was unnecessary to use an air-bearing spindle because tool failure governed the best finish that could be expected. All tools of diamond composition, whether single crystal or polycrystalline, wore at unacceptable rates. Based on present technology, it must be concluded that beryllium cannot be feasibly diamond turned to achieve an optical finish. (22 fig.) (auth)

A description is given of the data acquisition system used with the multiparticle spectrometer facility at Brookhaven. Detailed information is provided on that part of the system which connects the detectors to the data handler; namely, the detector electronics, device controller, and device port optical isolator.

The behavior of inert gases, particularly helium, in metals was studied in aluminum, copper, niobium and stainless steel. Emphasis was upon characterizing the state of helium in the metals and upon following the kinetics of precipitation and coalescence. Experimental techniques that are, in most cases, new to studies of inert gases in metals were employed. These include low- temperature specific heat, precision lattice parameter measurement, internal friction, computer simulation, and residual resistivit gamma , in addition to confirmatory electron microscopy. The single most important finding is that bubble coalescence takes place at rates which are much slower than was previously supposed and that the slow coalescence fits a model in which the bubble mobility required for coalescence is rate-limited by nucleation of facets on the bubble surface. The further understanding and subsequent potential ability to control rates of bubble and/or void coalescence will be important to the design of nuclear fuel and cladding materials. (auth)

Measurements have been made of the electrical resistivity, the acoustic wave speed, density, and water content of six groups of rock samples taken from Cenozoic volcanic units. It has been found from these measurements that the correlations between physical properties are significantly different in the case of volcanic rocks than in the case of sandstones and limestones. For a given porosity and water content, the resistivity of a volcanic rock is several fold greater than that of a sandstone or limestone. Also, there is a weaker correlation between acoustic wave speed and porosity in volcanic rocks than in sandstones and limestones. The effect of temperature on the properties of these rocks appears to be predictable from fundamental considerations to temperatures as high as 100/sup 0/C.

Recent developments in computer based systems for quantitative x-ray microanalysis, 4 Pi surface examination, Auger electron spectroscopy and Backscattered Microtopography measurement have extended the Scanning Electron Microscope's applications in ICF target development and production.

This appendix supplements Chapter II of the RDFOR Model documentation report. It consists of six tables: US total sector quantities, 1960-1975 in trillions of Btu; US fuel sector quantities, 1960-1975 in trillions of Btu; US fuel sector prices, 1960-1975 in constant 1975 dollars per million Btu; historical total sector quantities by region, 1960-1975 in trillions of Btu; historical energy prices by fuel/sector by region, 1960-1975 in constant 1975 dollars per million Btu; and historical energy quantities by fuel/sector by region, 1960-1975 in trillions of Btu.

The Department of Energy's Regional Demand Forecasting Model (RDFOR) is an econometric and simulation system designed to estimate annual fuel-sector-region specific consumption of energy for the US. Its purposes are to (1) provide the demand side of the Project Independence Evaluation System (PIES), (2) enhance our empirical insights into the structure of US energy demand, and (3) assist policymakers in their decisions on and formulations of various energy policies and/or scenarios. This report provides a self-contained user's manual for interpreting, utilizing, and implementing RDFOR simulation software packages. Chapters I and II present the theoretical structure and the simulation of RDFOR, respectively. Chapter III describes several potential scenarios which are (or have been) utilized in the RDFOR simulations. Chapter IV presents an overview of the complete software package utilized in simulation. Chapter V provides the detailed explanation and documentation of this package. The last chapter describes step-by-step implementation of the simulation package using the two scenarios detailed in Chapter III. The RDFOR model contains 14 fuels: gasoline, electricity, natural gas, distillate and residual fuels, liquid gases, jet fuel, coal, oil, petroleum products, asphalt, petroleum coke, metallurgical coal, and total fuels, spread over residential, commercial, industrial, and transportation sectors.

This report documents the demand forecasting model, RDFOR. Chapter I presents an overview of the structure of RDFOR as well as its linkages with other models within the PIES model. An important link between RDFOR and PIES is the Demand Interface System (DFACE) which prepares the output of RDFOR for input into PIES. Chapter II provides an in-depth analysis of the data bases used in the estimation and simulation of RDFOR. It presents an analysis of trends in energy data by fuel and by sector for both the United States as a whole and for each of the 10 DOE Regions. Chapter III provides a detailed analysis of the theoretical structure of RDFOR, analyzes a transportation sector model and a minor fuels sector model which differ in structure from the other sectors within RDFOR, and examines the econometric implementation of RDFOR. Chapter IV describes the simulation of RDFOR and its resultant forecasts. Emphasis is placed on the various restrictions and transformations performed prior to and during the simulation. A description of scenario implementation is also included. An analysis of the changes made in the simulation equations from the specification of the estimation equations is an important part of this chapter.

The primary goal for an ultraprecision turning machine is to have the capability to position precisely the cutting points of a tool along a defined contour with respect to the part. In order to accomplish this goal, the use of a stable-positional-reference system has become apparent. Several efforts have been made by representatives of the diamond-turning community to design such a needed reference system. Efforts made at Y-12 to design the needed system are reviewed.

By combining the electrically-driven, flying-plate, high-explosive initiator with well-known gas-gun technology, a novel method of generating and measuring shock pressures greater than 1 TPa has been developed. Called the electric gun, this system is competitive with laser or nuclear-driven, shock-wave, equation-of-state experiments in the 1 to 5 TPa range. Compared to those other methods, it has the advantage of simplicity, high precision, and low cost. In addition, its small size and low total energy allow it to be easily contained for experiments with toxic materials.
