Computer graphics for extracting information from data. [Various techniques for data display]

Description: Computer graphics which are useful for displaying and analyzing data are presented. Many classical and several newly developed graphical techniques in statistical data analysis are presented for small univariate and multivariate data sets. These include histograms, empirical density functions, pie charts, contour plots, a discriminant analysis display, cluster analysis, Chernoff ''faces,'' and Andrews' sine curves. Recent advances in data collection technology and computer data base management … more

Automation of multiple neutral beam injector controls at Lawrence Livermore Laboratory

Description: The computer control system used on the twelve Neutral Beams of the 2XIIB experiment at the Lawrence Livermore Laboratory (LLL) has evolved over the last three years. It is now in its final form and in regular use. It provides automatic data collection, reduction, and graphics presentation, as well as automatic conditioning, automatic normal operation, and processing of calorimeter data. This paper presents an overview of the capabilities and implementation of the current system, a detailed dis… more

Accountability methods for plutonium and uranium: the NRC manuals

Description: Four manuals containing methods for the accountability of plutonium nitrate solutions, plutonium dioxide, uranium dioxide and mixed uranium-plutonium oxide have been prepared by us and issued by the U.S. Nuclear Regulatory Commission. A similar manual on methods for the accountability of uranium and plutonium in reprocessing plant dissolver solutions is now in preparation. In the present paper, we discuss the contents of the previously issued manuals and give a preview of the manual now being p… more

Grain boundary concentration mapping by the CoRaD technique. [Cu--0. 074 to 1. 82 percent U; Count Rate Discriminator (CoRaD)]

Description: Copper and uranium were melted together in an electron beam furnace, rolled and vacuum annealed at 900/sup 0/C. Several samples were examined, varying in uranium content from 0.074 to 1.82 wt. percent. Each sample was mounted in a resin and polished for optical microscope and electron microprobe work. These samples, when viewed under an optical microscope exhibited three distinct phases: featureless grain surfaces, a light gray phase in the grain boundaries, and an occasional dark gray phase al… more

Rapid determination of uranium in natural waters by thermal emission mass spectrometry. Revision 1

Description: A six-inch radius mass spectrometer has been constructed and demonstrated to adequately analyze water samples for uranium concentrations down to 5 to 10 ng/liter (ppt). The precision and accuracy of the isotope-dilution, thermal emission method is sufficient to meet the needs of the Uranium Resources Evaluation (URE) project. A single analyst can analyze in excess of 50 samples per day, including all preparation and instrument time. This analysis rate will meet the economic constraints of the U… more
