7-GeV Advanced Photon Source : Conceptual Design Report

7-GeV Advanced Photon Source : Conceptual Design Report

Date: April 1987
Creator: Argonne National Laboratory
Description: During the past decade, synchrotron radiation emitted by circulating electron beams has come into wide use as a powerful, versatile source of x-rays for probing the structure of matter and for studying various physical processes. Several synchrotron radiation facilities with different designs and characteristics are now in regular operation throughout the world, with recent additions in this country being the 0.8-GeV and 2.5-GeV rings of NSLS at Brookhaven National Laboratory. However, none of the operating facilities has been designed to use a low-emittance, high-energy stored beam, together with modern undulator devices, to produce a large number of hard x-ray beams of extremely high brilliance. This document is a proposal to the Department of Energy to construct and operate high-energy synchrotron radiation facility at Argonne National Laboratory. We have now chosen to set the design energy of this facility at 7.0 GeV, with the capability to operate at up to 7.5 GeV.

²³⁵U(n,f), ²³⁸U(n, gamma), ²³⁸U(n,f), ²³⁹Pu(n,f) Reaction Rate Measurement Calibrations at ZPPR

Date: January 1987
Creator: Poenitz, W. P.; Maddison, D. W.; Gasidlo, J. M.; Carpenter, S.G. & Armani, R. J.
Description: New reference deposits for uranium-235, plutonium-239 and uranium-238 have been established with mass uncertainties of <0.2%. These new deposits replace the older reference deposits which were used during the last 17 years and improve the uncertainty of reaction rate measurements due to reference mass uncertainties by about a factor of 6. Measurements of the fission fragment absorption in 2 pi and low-geometry count rates. Two measurements of the uranium-238 capture rate in depleted uranium samples based upon the thermal cross sections of uranium-238(n, gamma), uranium-235(n,f) and plutonium-239(n,f) and based upon the americium-243 calibration technique confirm the ZPPR measurement technique within the quoted uncertainty of +/-0.5%

Accuracy of the Finite Analytic Method for Scalar Transport Calculations

Accuracy of the Finite Analytic Method for Scalar Transport Calculations

Date: September 1984
Creator: Vanka, S. P.
Description: The accuracy of the finite analytic method of discretizing fluid flow equations is assessed through calculations of multidimensional scalar transport. The transport of a scalar function in a uniform velocity flow field inclined with the finite-difference grid lines is calculated for a range of grid Peclet numbers and flow skewness. The finite analytic method is observed to be superior to the approach of constructing finite-difference analogs from locally one-dimensional resolution of the flow vector. However, the finite analytic method also produces appreciable errors locally in regions of steep variations, under conditions of large grid Peclet numbers, and skewness of the streamlines.

Accurate Numerical Solutions for Elastic-Plastic Models

Accurate Numerical Solutions for Elastic-Plastic Models

Date: March 1980
Creator: Schreyer, H. L.; Kulak, R. F. & Kramer, J. M.
Description: The accuracy of two integration algorithms is studied for the common engineering condition of a von Mises, isotropic hardening model under plane stress. Errors in stress predictions for given total strain increments are expressed with contour plots of two parameters: an angle in the pi plane and the difference between the exact and computed yield-surface radii.

Acoustic Leak Detection for District Heating Systems

Acoustic Leak Detection for District Heating Systems

Date: February 1988
Creator: Kupperman, D. S. & Karvelas, D. E.
Description: An acoustic leak detection facility was completed and used to evaluate the capability of piezoelectric sensors, accelerometers, and capacitance microphones to detect and locate gas and water leaks in underground district heating and cooling (DHC) piping. Leak detection sensitivity and location capabilities for DHC systems were estimated from laboratory data and from data obtained from the underground DH system in Scranton, Pennsylvania, where acoustic background noise levels and acoustic signals from field-induced steam leaks were acquired. Acoustic detection of leaks with flow rates of less than 10 gpm is possible at a distance of several hundred meters, with a location accuracy of a few meters. Although steam leaks of comparable mass loss can be detected over a similar range with transducers mounted on the pipe outer wall, location accuracy of a few meters over this range may only be possible with transducers in direct contract with the steam. Intrusive sensors may also be necessary to detect and locate leaks in plastic pipe.

Activities and Operations of the Advanced Computing Research Facility. January 1985 - July 1986

Activities and Operations of the Advanced Computing Research Facility. January 1985 - July 1986

Date: 1986
Creator: Mihaly, Tina & Pieper, Gail W.
Description: This report discusses research activities and operations of the Advanced Computing Research Facility (ACRF) at Argonne National Laboratory from January 1985 through June 1986. During this period, the Mathematics and Computer Science Division (MCS) at Argonne received incremental funding from the Applied Mathematical Sciences program of the DOE Office of Energy Research to operate computers with innovative designs that promise to be useful for advanced scientific research. Over a five-month period, four new commercial multiprocessors (an Encore Multimax, a Sequent Balance 21000, an Aliant FX/8, and an Intel iPSC/d5) were installed in the ACRF, creating a new wave of research projects concerning computer systems with parallel and vector architectures. A list of projects, publications, and users supported by the ACRF is included.
