Radiation studies of optical interferometric modulators with fast neutrons and high energy gamma-rays

Description: The possibility of using Ti : LiNbO{sub 3} and single mode fibers for nuclear particle detection and transmission in large-scale machines, such as Superconducting Super Collider, calls for a detailed radiation damage study. In this report, we present radiation studies on Ti : LiNbO{sub 3} Mach-Zehnder interferometric optical modulators with fast neutrons and high energy Gamma-rays.

Lasers and high-energy light as a decontamination tool for nuclear applications

Description: Light-aided decontamination (LAD) removal of paint and concrete layers is competitive with sand blasting rates. Remote operations, up to 137 m (450 ft), and lower waste volumes can provide cost, safety, and environmental advantages for nuclear facilities.

The Protein Data Bank: Present status and future plans

Description: The Protein Data Bank (PDB) archival database of dimensional structures of biological macromolecules, an international resource facility, contains information on protein, DNA, RNA, virus and carbohydrate structures. While the vast majority of PDB entries represent crystal structures, results from NMR and theoretical modeling strudies also are included. PDB, which in July 1992 contained 957 atomic coordinate entries, currently is experiencing a time of explosive growth. The present deposition rate is ca. 50 structures per month, doubling in less than two years. Responding to the challenge posed by this. rising data flow, over the past 18 months PDB has attracted increased funding to implement important enhancements of the resource. A rapid pre-release of entries pending for input was inaugurated in April 1992, and a substantial fraction of the accumulated backlog of pending entries is now available via FTP and e-mail in prerelease form. Extrapolation of current data rates suggests that by the year 2000 PDB may contain over 25,000 structures. PDB`s plans, to manage this voluminous amount of data, include the development of PDB-AUTHORIN software to allow depositors to do most of the preparation and validation of their own entries, and a comprehensive upgrade of PDB contents to add new data items and convert the current interchange format to the Crystallographic Information File (CIF) standard established by the International Union of Crystallography (IUCr).

Statistics of time averaged atmospheric scintillation

Description: A formulation has been constructed to recover the statistics of the moving average of the scintillation Strehl from a discrete set of measurements. A program of airborne atmospheric propagation measurements was analyzed to find the correlation function of the relative intensity over displaced propagation paths. The variance in continuous moving averages of the relative intensity was then found in terms of the correlation functions. An empirical formulation of the variance of the continuous moving average of the scintillation Strehl has been constructed. The resulting characterization of the variance of the finite time averaged Strehl ratios is being used to assess the performance of an airborne laser system.

Aqueous electrolyte modeling in ASPEN PLUS{trademark}

Description: The presence of electrolytes in aqueous solutions has long been recognized as contributing to significant departures from thermodynamic ideality. The presence of ions in process streams can greatly add to the difficulty of predicting process behavior. The difficulties are increased as temperatures and pressures within a process are elevated. Because many chemical companies now model their processes with chemical process simulators it is important that such codes be able to accurately model electrolyte behavior under a variety of conditions. Here the authors examine the electrolyte modeling capability of ASPEN PLUS{trademark}, a widely used simulator. Specifically, efforts to model alkali metal halide and sulfate systems are presented. The authors show conditions for which the models within the code work adequately and how they might be improved for conditions where the simulator models fail.

A two-dimensional ACAR study of untwinned YBa{sub 2}Cu{sub 3}O{sub 7-x}

Description: We have carried out 2D-ACAR measurements on an untwinned single crystal of YBa{sub 2}Cu{sub 3}O{sub 7-x} as a function of temperature, for five temperatures ranging from 30K to 300K. We show that these temperature dependent 2D-ACAR spectra can be described to a good approximation as a superposition of two temperature independent spectra with temperature dependent weighting factors. We show further how the data can be used to correct for the ``background`` in the experimental spectrum. Such a ``background corrected`` spectrum is in remarkable accord with the corresponding band theory predictions, and displays in particular clear signatures of the electron ridge Fermi surface.

Using object oriented analysis and design to study the SSCL SDC computing system

Description: A joint study between the Computer Working Group of the SSC Solenoidal Detector Collaboration (SDC) and IBM`s Federal Sector Division is focusing on the use of Object Oriented Analysis and Design on the SDC Offline Computing System. One key challenge of the analysis is to discover an efficient way to store and subsequently retrieve raw and reconstructed event data, estimated to be 2 petabytes per year. The Object Oriented approach being used during the analysis and early design is intended to yield a smooth transition to detailed design, prototyping and implementation. The object oriented approach is used as a subprocess of a larger process used by IBM FSD, i.e., a systematic approach to architecting and integrating large complex systems. A description of the overall process and early results are described in a study report produced jointly by the SDC and IBM FSD. The overall process focuses on requirements analysis, operational concept development, problem domain decomposition, development and selection of candidate architectures, automated performance modeling and software architecture. This paper will focus primarily on software architecture. The high level software architecture is viewed as a layered stack consisting of: system services, common physics application framework and unique physics applications. Object oriented analysis is being used to investigate the data storage and management of the event data. An object hierarchy is being created and operational concept scenarios are being used to validate the design. Several database prototypes can then be developed, e.g. object oriented or relational, to prove the concept. The object oriented development is fundamentally different from traditional approaches to design, such as those based exclusively on data flow. Object oriented decomposition more closely models a person`s perception of reality, hence the developed system is more understandable, extensible, and maintainable.
