7-GeV Advanced Photon Source Beamline Initiative. Conceptual Design Report

7-GeV Advanced Photon Source Beamline Initiative. Conceptual Design Report

Date: May 1993
Creator: Argonne National Laboratory
Description: The DOE is building a new generation 6-7 GeV Synchrotron Radiation Source known as the Advanced Photon Source (APS) at Argonne National Laboratory. This facility, to be completed in FY 1996, can provide 70 x-ray sources of unprecedented brightness to meet the research needs of virtually all scientific disciplines and numerous technologies. The technological research capability of the APS in the areas of energy, communications and health will enable a new partnership between the DOE and US industry. Current funding for the APS will complete the current phase of construction so that scientists can begin their applications in FY 1996. Comprehensive utilization of the unique properties of APS beams will enable cutting-edge research not currently possible. It is now appropriate to plan to construct additional radiation sources and beamline standard components to meet the excess demands of the APS users. In this APS Beamline Initiative, 2.5-m-long insertion-device x-ray sources will be built on four straight sections of the APS storage ring, and an additional four bending-magnet sources will also be put in use. The front ends for these eight x-ray sources will be built to contain and safeguard access to these bright x-ray beams. In addition, funds will be provided ...

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.

7-GeV Advanced Photon Source Instrumentation Initiative. Conceptual Design Report

7-GeV Advanced Photon Source Instrumentation Initiative. Conceptual Design Report

Date: October 1992
Creator: Argonne National Laboratory
Description: In this APS Instrumentation Initiative, 2.5-m-long and 5-m-long insertion-device x-ray sources will be built on 9 straight sections of the APS storage ring, and an additional 9 bending-magnet sources will also be put in use. The front ends for these 18 x-ray sources will be built to contain and safeguard access to these bright x-ray beams. In addition, funds will be provided to build state-of-the-art insertion-device beamlines to meet scientific and technological research demands well into the next century. This new initiative will also include four user laboratory modules and a special laboratory designed to meet the x-ray imaging research needs of the users. The Conceptual Design Report (CDR) for the APS Instrumentation Initiative describes the scope of all the above technical and conventional construction and provides a detailed cost and schedule for these activities. According to these plans, this new initiative begins in FY 1994 and ends in FY 1998. The document also describes the preconstruction R & D plans for the Instrumentation Initiative activities and provides the cost estimates for the required R & D.

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.
