Four-D propagation code for high-energy laser beams: a user's manual
This manual describes the use and structure of the June 30, 1976 version of the Four-D propagation code for high energy laser beams. It provides selected sample output from a typical run and from several debug runs. The Four-D code now includes the important noncoplanar scenario feature. Many problems that required excessive computer time can now be meaningfully simulated as steady-state noncoplanar problems with short run times.

Plane stress calculations with a two dimensional elastic-plastic computer program. [HEMP]
In the study of ductile fracture it is useful to simulate fracture on the computer under plane stress conditions. In general, this is a three dimensional problem. Presented here is a method for adapting a two dimensional elastic-plastic computer program to calculate problems in plane stress as well as plane strain geometry. A simulation of a tension test of a flat aluminum plate pulled to failure is calculated with the modified two dimensional program. The results are compared with a fully three dimensional calculation. Finally a comparison is made with an experiment to demonstrate the effectiveness of the computational methods for studying fracture of work hardening materials.

Use of the Borrmann Effect to Produce Nearly Monoenergetic X Rays
The use of the Borrmann effect to produce nearly monoenergetic x rays is described. Both theoretical and experimental results are presented for the energy range from 15 to 55 keV. Peak shape, full-widths at half-maximum, and intensities are discussed. In addition, a brief description of a computer code for calculating the theoretical results is given.

Simple example of track finding by Fourier transform and possibilities for vector or optical processors
Simple examples of finding tracks by Fourier transform with filter or correlation function are presented. Possibilities for using this method in more complicated real situations and the processing times which might be achieved are discussed. The method imitates the simplest examples in the literature on optical pattern recognition and optical processing. The possible benefits of the method are in speed of processing in the optical Fourier transform wherein an entire picture is processed simultaneously. The speed of a computer vector processor may be competitive with present electro-optical devices. 2 refs., 6 figs.

Quality Assurance Program Description---DWPF
This document describes the Westinghouse Savannah River Company's (WSRC) Quality Assurance Program for Defense Waste Processing at the Savannah River Site (SRS). It identifies and describes the planned activities that constitute the required Quality Assurance Program. The work to which the Quality Assurance Program applies includes both the qualification and production of high-level waste forms. The end result of the program is to provide confidence that these high-level waste forms may be safely and acceptably used to dispose of the radioactive waste that results from activities at SRS in support of national defense.

Analysis of owner design specifications for snubbers. Report 2
The report discusses and evaluates the adequacy of buyer specifications for snubbers. Technical specifications for snubbers (hydraulic and mechanical) were studied in detail in an effort to define the ''fundamental needs'' of the industry with respect to characteristics of snubbers during operation. In the course of this study, it was determined that there is insufficient consensus among users to make such a definition. Authorities in the fields of structural dynamics, structural systems design, and snubber design were also consulted for additional information. Information from these sources is incorporated to identify the fundamental areas of concern, areas where consensus is lacking, and problems to be resolved in order to establish meaningful standards for this equipment.

Cost-Benefit Analysis of Advanced, Sanitary Sewage Treatment at Rocky Flats
A small, secondary treatment plant for processing sanitary wastes was upgraded by the addition of tertiary treatment (chemical treatment and final clarification) and mixed-media filtration. Operational data showed that the tertiary treatment significantly reduced pollutants. Filtration further reduced suspended solids significantly and removed some additional phosphorus; however, no additional reduction in total oxygen demand or in nitrogen was noted. Detailed analyses of costs for construction and routine operations showed the cost of tertiary treatment was small compared to costs associated with mixed-media filtration.

Experimental study of interactions of highly charged ions with atoms at keV energies
This Progress Report describes the experimental work carried out, and the work in progress, at the Cornell EBIS Laboratory during the period 7/1/1991 to 6/30/1992. During this period, a number of experiments were carried out. The absolute values of the total, one, two and three electron transfer cross sections for highly charged argon ions (8{le}q{le}16) colliding with argon at 2.3 qkev laboratory energy were measured. The distribution of recoil ions and molecular fragments formed in highly charged ion atom and molecule collisions was measured in order to help the interpretation of electron spectra in the 40--320 eV energy range emitted in Ar{sup q+}+Ar(8{le}q{le}16) collisions at 2.3 qkeV that were measured in our laboratory. The interpretation of the electron spectra is still under way. A new collision chamber was built which contains an ion decelerating lens system and a high resolution monochromator-analyzer combination. Ions extracted from the Cornell Electron Beam Ion Source were successfully decelerated from 2.3 qkeV down to 30 qeV Preliminary 0{degree} translational energy spectra for Ar{sup l2+} on Ar at a collision energy of 38.6 qeV show a 0.56 qeV resolution. Work is in progress to extend measurements of cross sections and recoil ion charge state distributions down …

Preliminary report on retardation factors and radionuclide migration
Available data on distribution coefficients for the biologically important radionuclides present in high-level waste were used to estimate retardation factors (K/sub f/) for a mass transport hydrologic model. The radionuclides were divided into 3 groups: fission products with no sorption (K/sub f/ = 1), fission products with sorption (K/sub f/ = 10/sup 2/), and the actinides and their daughter products (K/sub f/ = 10/sup 4/). Minimum and maximum values were assigned the latter two groups. Uncertainties as a function of time were estimated at +- an order of magnitude. 39 references, 5 tables.

Mass spectrometric analytical services and research activities to support coal-liquid characterization research. Quarterly report, September 9, 1976--December 8, 1976. [11 refs]
Modification of the combined FI/EI ion source to permit operation in the FD mode is underway. Oxidation-reduction and activation cells were fabricated and assembly of the vacuum system for the activation cell is in progress. High- and low-voltage power supplies needed for emitter preparation were constructed. The sensitivity for field ionization of decane relative to that for ethylbenzene was measured as a function of binary mixture composition, ion-source temperature, and field strength. A gallium frit is being added to the all-glass inlet system. The purity of 25 saturates and naphthenes and 10 single-ring aromatics substituted with alkyl groups was checked using FID/GC.
