The goal of this demonstration was to show that it is possible to generate electronic signals that can accurately mimic the signals that are produced by a high-purity germanium (HPGe) gamma-ray detector. As an example of this fidelity, we decided to show that it was possible to perform a complex, multiplet-resolution analysis of a portion of the spectrum acquired from the gamma-ray spectrum synthesizer. We further showed that the results of this analysis were consistent with what would be obtained from a spectrum acquired from a real plutonium source and a real HPGe detector. The gamma-ray synthesizer used in the JRC Ispra demonstration was our first laboratory prototype. In this version of the synthesizer we produced signals that mimicked the output of an HPGe detector preamplifier. Although not shown at Ispra, we have also demonstrated that we can produce signals that mimic the signals produced in the detector itself.

Major scientific and technological breakthroughs played a pivotal role in our ability to win the Cold War. The possibility of a different type of war, in response to terrorism, has long been recognized. Indeed, countermeasures to address specific terrorist acts have been developed and are deployed, for example, at special sporting and political events. The current threat environment, however, has created an intense and compelling set of concerns; consequently, the challenge to the scientific Community to develop new concepts and products on an accelerated timeframe is clear. Also, the spectrum of terrorist threats is broad. It includes the use of conventional, chemical, biological, and nuclear and radiological weapons, not to mention cyber-based attacks. The imperatives for advances have been amplified now that attacks are clearly possible within the U.S. borders. For example, advanced sensors and detectors that are able to monitor the proliferation of all the above warfare agents and their movement at entry points into the U.S. are clearly needed. The investments over the last decades in research and development efforts at the U.S. Department of Energy (DOE) national laboratories in nonproliferation have led unique technologies and detection capabilities that have proved useful; yet, many challenges remain. In particular, …

The popularity of trucks in the class 2 category--that is, those with a 6,000 to 10,000 pounds (lbs) gross vehicle weight rating (GVWR)--has increased since the late 1970s/early 1980s. The purpose of this research is to identify and examine vehicles in the upper portion of the class 2 weight range (designated as vehicle class 2b) and to assess their impact. Vehicles in class 2b (8,500-10,000 lbs GVWR) include pickup trucks, sport utility vehicles (SUVs), and large vans (i.e., not minivans). Oak Ridge National Laboratory researched each individual truck model to determine which models were class 2b trucks and arrived at four methodologies to derive sales volumes. Two methods--one for calendar year and one for model year sales--were recommended for producing believable and reliable results. The study indicates that 521,000 class 2b trucks were sold in calendar year 1999--6.4% of sales of all trucks under 10,000 lbs. Eighty-two percent of class 2b trucks sold in 1999 were pickups; one third of class 2b trucks sold in 1999 were diesel. There were 5.8 million class 2b trucks on the road in 2000, which amounts to 7.8% of all trucks under 10,000 lbs. Twenty-four percent of the class 2b truck population is diesel. …

Run 2 of the Tevatron began in early 2001 after extensive upgrades to both the machine and the CDF and D0 detectors. For CDF, new tracking detectors, increased muon coverage, state-of-the-art front end electronics, pipelined triggering, and a complete overhaul of the DAQ have made it a very powerful tool to explore physics of all kinds. The status of CDF in Run 2 is presented, along with a first glimpse of CDF data.

The purpose of the research reported here was to assess the leveraging benefits attributable to the U.S. Department of Energy's (DOE's) Industrial Assessment Center (IAC) Program. The term leveraging as used in this study refers to any additional support received by a university-based, IAC-sponsored center that the center would not have received had the IAC Program not been in place. Twenty-two IACs provided information about 120 leveraging activities over the 1997-2001 period. IAC directors indicated that the support for 115 of these projects was linked to the existence of DOE's IAC Program and the experience gained from their participation in the program. Ninety-three of the IAC-influenced projects were quantified, for a monetary value of $5,948,931. The average annual leveraged support was $1,189,786 over the time frame examined. Typical contributors of leveraged support were state governments, utilities, industry, universities, and other DOE and federal agencies. Most of the support was provided to conduct assessments outside of IAC Program criteria (e.g., assessments of government buildings or large manufacturing plants). Significant leveraged support was also provided to IACs for educational activities--such as workshops, seminars, and training--and for miscellaneous energy-related technical projects.

The goal of this project is to apply advanced computer-aided modeling techniques for simulating coupled radiation transfer present in the bulk growth of aluminum nitride (AlN) single-crystals. Producing and marketing high-quality single-crystals of AlN is currently the focus of Crystal IS, Inc., which is engaged in building a new generation of substrates for electronic and optical-electronic devices. Modeling and simulation of this company's proprietary innovative processing of AlN can substantially improve the understanding of physical phenomena, assist design, and reduce the cost and time of research activities. This collaborative work supported the goals of Crystal IS, Inc. in process scale-up and fundamental analysis with promising computational tools.

Problems with long shaft pumps are becoming clearer due to increased use, better instrumentation, more analysis, and increased testing activity. The problems are with reliability and not with hydraulic performance. The root cause of reliability problems is usually excessive vibration caused by design. The outlook for satisfactory pumps is improved as understanding of problems increases. Promising developments are emerging such as the tilt pad bearing. Alternative configurations, such as gas filled columns and submerged motor pumps, will require development. Continued development, in general, should be expected due to changing technology and industry changes. This report describes thirteen distinct pump programs starting with leakage of original mixer pumps in the 1980s and ending with the testing of tilt pad bearings now in progress. Eight of the programs occurred from 1996 to 2000. All involve long shaft pumps; all involve testing at TNX; and all involve a problem of some kind. The common technical issue among the activities is vibration and shaft (or rotor) instability due to journal bearings. In every case, excessive shaft vibration is a reasonable and probable explanation for some or all of the problems.

Tool Gear is designed to allow tool developers to insert instrumentation code into target programs using the DPCL library. This code can gather data and send it back to the Client for display or analysis. Tools can use the Tool Gear client without using the DPCL Collector. Any collector using the right protocols can send data to the Client for display and analysis. However, this document will focus on how to gather data with the DPCL Collector. There are three parts to the task of using Tool Gear to gather data through DPCL: (1) Write the instrumentation code that will be loaded and run in the target program. The code should be in the form of one or more functions, which can pass data structures back to the Client by way of DPCL. The collections of functions is compiled into a library, as described in this report. (2) Write the code that tells the DPCL Collector about the instrumentation and how to forward data back to the Client. (3) Extend the client to accept data from the Collector and display it in a useful way. The rest of this report describes how to carry out each of these steps.

We present an algorithm for end-to-end out-of-core simplification and view-dependent visualization of large surfaces. The method consists of three phases: (1) memory insensitive simplification; (2) memory insensitive construction of a level-of-detail hierarchy; and (3) run-time, output sensitive, view-dependent rendering and navigation of the mesh. The first two off-line phases are performed entirely on disk, and use only a small, constant amount of memory, whereas the run-time component relies on memory mapping to page in only the rendered parts of the mesh in a cache coherent manner. As a result, we are able to process and visualize arbitrarily large meshes given a sufficient amount of disk space--a constant multiple of the size of the input mesh. Similar to recent work on out-of-core simplification, our memory insensitive method uses vertex clustering on a uniform octree grid to coarsen a mesh and create a hierarchy, and a quadric error mettic to choose vertex positions at all levels of resolution. We show how the quadric information can be used to concisely represent vertex position, surface normal, error, and curvature information for anisotropic view-dependent coarsening and silhouette preservation. The focus of this paper is on the out-of-core construction of a level-of-detail hierarchy---our framework is general …

The National Museum of the Pacific War presents an oral interview with Carroll Prescott. Prescott joined the Marine Corps in July 1941 and was at Salt Lake Camp (about a mile from Pearl Harbor) on December 7, 1941. He was assigned to the 4th Defense Battalion as a gunner on a 3-inch anti-aircraft gun. His whole battalion was on the aircraft tender USS Tangier on December 25 when the entire task force turned around; they were 2-3 hours from landing on Wake. He left Pearl Harbor on March 18, went to the New Hebrides and landed on Vela Lavella on August 14, 1943. They went to New Zealand and were retrained on the 3-inch guns. Prescott went over the hill in New Zealand. He was on Hilo, Hawaii (training for the invasion of Japan) when he heard the war was over. They went to Sasebo, Japan and he stood guard duty. There's a photocopy picture of Prescott in the folder.
