ORBXYZ: a 3D single-particle orbit code for following charged-particle trajectories in equilibrium magnetic fields

Description: The single particle orbit code, TIBRO, has been modified extensively to improve the interpolation methods used and to allow use of vector potential fields in the simulation of charged particle orbits on a 3D domain. A 3D cubic B-spline algorithm is used to generate spline coefficients used in the interpolation. Smooth and accurate field representations are obtained. When vector potential fields are used, the 3D cubic spline interpolation formula analytically generates the magnetic field used to… more

Coal as an option for power generation in US territories of the Pacific

Description: A survey of general considerations relating to the use of coal in US territories and trust territories of the Pacific suggests that coal is a viable option for power generation. Future coal supplies, principally from Australia and the west coast of America, promise to be more than adequate, but large bulk carriers will probably not be able to land coal directly because of inadequate port facilities. Hence, smaller than Panamax-class vessels (60,000 dwt) or some arrangement utilizing self-loadin… more

Improved 50 ps response x-ray detector with optical applications

Description: We have improved the impulse response characteristics of the LLNL 50 ps detector significantly. The detector has also been improved mechanically to permit much greater ease of assembly and repair. We are investigating modified versions of this design for optical applications. The detector was developed to complement the recording capability of our Thomson-CSF 4 GHz oscilloscopes in laser driven ICF fusion experiments research.

A Summary of Prevailing Views on the Sources of Inflation

Description: It is the purpose of this paper to present the range of viewpoints concerning the causes of inflation. Inflation is defined and distinguished from changes' in relative prices. The Monetarist, Post-Keynesian, and neo-Keynesian positions are discussed to illustrate the variety of perceptions as to the sources of sustained increases in the general price level.

Effect of solid particles on the turbulent flow of a round gaseous jet. A mathematical and experimental study. Quarterly technical progress report, May 1, 1981-October 30, 1981

Description: Progress in mathematical and experimental studies aimed at modeling and measuring flows rates for the two-phase gases with dispersed particles turbulent flows in jets is reported. Exact transport equations of mass and momentum for the two phases, the carrier fluid's kinetic energy of turbulence and its dissipation rate have been derived for incompressible two-phase flows. The modeling of the various turbulence correlations has been completed. The finite-difference formulation of the equations i… more

Carrier sense data highway system. [Patent for a two-way Data Transmission System]

Description: A data transmission system is disclosed which includes a transmission medium which has a certain propagation delay time over its length. A number of data stations are successively coupled to the transmission medium for communicating with one another. Each of the data stations includes a transmitter for originating signals, each signal beginning with a carrier of a duration which is at least the propagation delay time of the transmission medium. Each data station also includes a receiver which r… more

Comparative analysis of LMFBR licensing in the United States and other countries - notably France. Executive summary

Description: The safety-related design aspects and licensing experiences of LMFBR projects in other democratic countries have been studied and contrasted to those in the United States in order to understand the importance of different approaches to safety, and also to understand better the system of the United States. The regulatory systems and LMFBR programs of France and the United States are contrasted in detail, and that of West Germany is also studied. The programs of Japan and the United Kingdom recei… more

Silicon materials task of the Low-Cost Solar Array Project: Phase IV. Effects of impurities and processing on silicon solar cells. Twenty-first quarterly report, October-December 1980

Description: The overall objective of this program is to define the effects of impurities, various thermochemical processes, and any impurity-process interactions upon the performance of terrestrial solar cells. The results of the study form a basis for silicon producers, wafer manufacturers, and cell fabricators to develop appropriate cost-benefit relationships for the use of less pure, less costly solar grade silicon. Cr is highly mobile in silicon even at temperatures as low as 600/sup 0/C. Contrasting w… more

Analytical approach for confirming the achievement of LMFBR reliability goals

Description: The approach, recommended by GE-ARSD, for confirming the achievement of LMFBR reliability goals relies upon a comprehensive understanding of the physical and operational characteristics of the system and the environments to which the system will be subjected during its operational life. This kind of understanding is required for an approach based on system hardware testing or analyses, as recommended in this report. However, for a system as complex and expensive as the LMFBR, an approach which … more

Nuclear criticality information system

Description: The nuclear criticality safety program at LLNL began in the 1950's with a critical measurements program which produced benchmark data until the late 1960's. This same time period saw the rapid development of computer technology useful for both computer modeling of fissile systems and for computer-aided management and display of the computational benchmark data. Database management grew in importance as the amount of information increased and as experimental programs were terminated. Within the … more

Engineering Sheets of 12 Metre Solenoid

Description: The solenoid design follows closely the considerations qiven in {bar p} note 116. In particular we try to make the solenoid undivided, but with a centre tap for the cooling water. We found a variant for the centre tap, so that the two layers are now electrically in series. Due to the very long length, it seems better not to fill the clearance between return yoke and OD of the second layer with epoxy. Instead, we support and adjust the coil every 2 m with three bolts at 120 deqrees screwed in th… more

Biological and clinical dosimetry. Progress report, October 1, 1980-September 30, 1981

Description: A second measurement of the event size distribution for 20 MeV neutrons was carried out at Ohio University to determine the reproducability of results. Again a significant difference between measurement and theoretical calculations by Caswell and Coyne was found. The measured fraction of events due to alpha particles was significantly lower than that predicted by the calculation of Casell and Coyne. Furthermore, the discrepancies with the theoretical calculations made by Caswell and Coyne were … more

Simultaneous recording of optical and x-ray signals in laser fusion

Description: To better understand the processes involved, and to better model their effects on target implosions, it is important that we know the temporal evolution of target x rays with respect to the driving laser pulse. We use an S-1 photocathode optical streak camera to simultaneously record incident and reflected 1.06-..mu..m laser light, and suprathermal (> 30 keV) x rays with good temporal resolution (10 ps at 1.06-..mu..m) and good dynamic range (10/sup 3/). The shape of the suprathermal x-ray sign… more

Spheromak reactor-design study

Description: A general overview of spheromak reactor characteristics, such as MHD stability, start up, and plasma geometry is presented. In addition, comparisons are made between spheromaks, tokamaks and field reversed mirrors. The computer code Sphero is also discussed. Sphero is a zero dimensional time independent transport code that uses particle confinement times and profile parameters as input since they are not known with certainty at the present time. More specifically, Sphero numerically solves a gi… more
