Assembly Manual for the Berkeley Lab Cosmic Ray Detector
The Berkeley Lab Cosmic Ray Detector consists of 3 main components that must be prepared separately before they can be assembled. These components are the scintillator, circuit board, and casing. They are described in the main sections of this report, which may be completed in any order. Preparing the scintillator paddles involves several steps--cutting the scintillator material to the appropriate size and shape, preparing and attaching Lucite cookies (optional), polishing the edges, gluing the end to the photomultiplier tube (optional), and wrapping the scintillator. Since the detector has 2 paddles, each of the sections needs to be repeated for the other paddle.

Assessment of Reactivity Margins and Loading Curves for PWR Burnup Credit Cask Designs
This report presents studies to assess reactivity margins and loading curves for pressurized water reactor (PWR) burnup-credit criticality safety evaluations. The studies are based on a generic high-density 32-assembly cask and systematically vary individual calculational (depletion and criticality) assumptions to demonstrate the impact on the predicted effective neutron multiplication factor, k{sub eff}, and burnup-credit loading curves. The purpose of this report is to provide a greater understanding of the importance of input parameter variations and quantify the impact of calculational assumptions on the outcome of a burnup-credit evaluation. This study should provide guidance to regulators and industry on the technical areas where improved information will most enhance the estimation of accurate subcritical margins. Based on these studies, areas where future work may provide the most benefit are identified. The report also includes an evaluation of the degree of burnup credit needed for high-density casks to transport the current spent nuclear fuel inventory. By comparing PWR discharge data to actinide-only based loading curves and determining the number of assemblies that meet the loading criteria, this evaluation finds that additional negative reactivity (through either increased credit for fuel burnup or cask design/utilization modifications) is necessary to accommodate the majority of current spent …

BTeV - A dedicated B experiment at the Tevatron
BTeV is a dedicated b-physics experiment that is expected to begin operation at the Fermilab Tevatron in 2008. BTeV is designed to take full advantage of the large production cross section of b particles (including B{sub S}) in high energy hadron collisions. A quick description of the BTeV spectrometer is given in this paper. Two unique aspects of BTeV, the pixel-based trigger and the high quality lead tungstate electromagnetic calorimeter, are described in slightly greater detail.

Clean Air Act Issues in the 108th Congress
Clean air issues were discussed at length in the 107th Congress, but legislation was not enacted, leaving the same issues for possible consideration in the 108th. With new leadership in the Senate, the prospects for such legislation and its content are likely to change. Further, the Senate committee of jurisdiction (Environment and Public Works) will almost certainly focus first on consideration of highway and transit funding (the authorization for which, known as TEA21, expires at the end of FY 2003). Thus, although there is some interest in considering broad changes to the Clean Air Act, the more immediate prospect is for targeted proposals that might be attached to re-authorization of TEA21.

Critical Infrastructures: Background, Policy, and Implementation
The nation’s health, wealth, and security rely on the production and distribution of certain goods and services. The array of physical assets, processes and organizations across which these goods and services move are called critical infrastructures (e.g. electricity, the power plants that generate it, and the electric grid upon which it is distributed). Computers and communications, themselves critical infrastructures, are increasingly tying these infrastructures together. This report aims to address the concern that this reliance on computers and computer networks raises the vulnerability of the nation’s critical infrastructures to “cyber” attacks.

Daylight Saving Time
Currently, in most parts of the United States, timepieces are moved forward one hour in the spring and back one hour in the fall to provide an extended daylight period during the summer months. This is known as Daylight Saving Time (DST). Much debate and many changes led to this present practice. This report provides a brief history of the issues surrounding DST, an outline of the legislation that created and modified it, and a list of references to more discussions.

The development of a compact positron tomograph for prostate imaging
We give design details and expected image results of a compact positron tomograph designed for prostate imaging that centers a patient between a pair of external curved detector banks (ellipse: 45 cm minor, 70 cm major axis). The bottom bank is fixed below the patient bed, and the top bank moves upward for patient access and downward for maximum sensitivity. Each bank is composed of two rows (axially) of 20 CTI PET Systems HR+ block detectors, forming two arcs that can be tilted to minimize attenuation. Compared to a conventional PET system, our camera uses about one-quarter the number of detectors and has almost two times higher solid angle coverage for a central point source, because the detectors are close to the patient. The detectors are read out by modified CTI HRRT data acquisition electronics. The individual detectors are angled in the plane to point towards the prostate to minimize reso

Evaluation of PFP Furnace Systems for Thermal Stabilization of Washed High Chloride Plutonium Oxide Items
High chloride content plutonium (HCP) oxides are impure plutonium oxide scrap which contains NaCl, KCl, MgCl2 and/or CaCl2 salts at potentially high concentrations and must be stabilized at 950 C per the DOE Standard, DOE-STD-3013-2000. The chlorides pose challenges to stabilization because volatile chloride salts and decomposition products can corrode furnace heating elements and downstream ventilation components. A high-temperature furnace (same make and model as used at the RMC at Plutonium Finishing Plant) and the associated offgas system were set up at PNNL to identify system vulnerabilities and to investigate alternative materials and operating conditions that would mitigate any corrosion and plugging of furnace and offgas components. The key areas of interest for this testing were the furnace heating elements, the offgas line located inside the furnace, the offgas line between the furnace and the filter/knockout pot, the filter/knockout pot, the sample boat, and corrosion coupons to evaluate alternative materials of construction. The evaluation was conducted by charging the furnace with CeO2 that had been impregnated with a mixture of chloride salts (selected to represent the expected residual chloride salt level in washed high chloride items) and heated in the furnace in accordance with the temperature ramp rates and hold …

K-Means Re-Clustering-Algorithmic Options with Quantifiable Performance Comparisons
This paper presents various architectural options for implementing a K-Means Re-Clustering algorithm suitable for unsupervised segmentation of hyperspectral images. Performance metrics are developed based upon quantitative comparisons of convergence rates and segmentation quality. A methodology for making these comparisons is developed and used to establish K values that produce the best segmentations with minimal processing requirements. Convergence rates depend on the initial choice of cluster centers. Consequently, this same methodology may be used to evaluate the effectiveness of different initialization techniques.

Lessons Learned From Electricity Restructuring: Transition to Competitive Markets Underway, but Full Benefits Will Take Time and Effort to Achieve
A chapter report issued by the General Accounting Office with an abstract that begins "The electricity industry in the United States is undergoing major change, the outcomes of which will affect every consumer. The industry is restructuring from one where electricity prices are set by regulation to one in which competitive markets set the price. GAO was asked to report on the extent to which federal and state actions, to date, have achieved the goal of restructuring. GAO discusses lessons learned from efforts to date."
