The proposed Next Linear Collider (NLC) will require over 1400 adjustable quadrupoles between the main linacs' accelerator structures. These 12.7 mm bore quadrupoles will have a range of integrated strength from 0.6 to 138 Tesla, with a maximum gradient of 141 Tesla per meter, an adjustment range of +0 to {minus}20% and effective lengths from 324 mm to 972 mm. The magnetic center must remain stable to within 1 micron during the 20% adjustment. In an effort to reduce costs and increase reliability, several designs using hybrid permanent magnets have been developed. Four different prototypes have been built. All magnets have iron poles and use Samarium Cobalt to provide the magnetic fields. Two use rotating permanent magnetic material to vary the gradient, one uses a sliding shunt to vary the gradient and the fourth uses counter rotating magnets. Preliminary data on gradient strength, temperature stability, and magnetic center position stability are presented. These data are compared to an equivalent electromagnetic prototype.

This report discusses the Better Education for Students and Teachers Act, which would eliminate the requirement for educational services to children with disabilities in certain situations.

The small asymmetries measured at G{sub {gamma}} = 7.5 during the RHIC spin commissioning were a serious concern. In earlier runs, asymmetries double those from the spin commissioning time (September 2000) had sometimes been observed, and there had been few changes to the AGS polarimeter hardware or operating conditions. Recently, the observed changes in the asymmetries measured at G{sub {gamma}} = 7:5 have been ascribed to contamination of the carbon target asymmetry with that from the fishline target and vice-versa, because of the sizeable beam spot size compared to the separation of the targets. This note addresses this hypothesis using the observed asymmetries. This problem could directly impact spin physics at RHIC.

The United States and Russia signed the second Strategic Arms Reduction Treaty (START II) on January 3, 1993. This report presents the background on the Russian parliament approval of the START II ratification. The report also discusses the linkage between U.S. withdrawal from ABM treaty and Russia’s possible withdrawal from START II. It discusses the alternative approaches for the United States and the future for the U.S.-Russian arms control process.

Beam-induced radiation effects have been simulated for 20 and 50 GeV muon storage rings designed for a Neutrino Factory. It is shown that by appropriately shielding the superconducting magnets, quench stability, acceptable dynamic heat loads, and low residual dose rates can be achieved. Alternatively, if a specially-designed skew focusing magnet without superconducting coils on the magnet's mid-plane is used, then the energy is deposited preferentially in the warm iron yoke or outer cryostat layers and internal shielding may not be required. In addition to the component irradiation analysis, shielding studies have been performed. Calculations of the external radiation were done for both designs but the internal energy deposition calculations for the 20 GeV Study-2 lattice are still in progress.

Thin layers of photoresist were spin coated onto silicon wafers, and then carbonized to form smooth carbon films by heating in nitrogen for 1 hour at temperatures between 600 to 1100 C. Well-defined carbon microstructures on Si wafers that are being considered for electrodes in a microbattery concept were obtained by additional processing steps involving patterning and lithography of the photoresist prior to carbonization. The status of the fabrication of carbon microelectrodes obtained by pyrolysis of photoresist, characterization of the carbons by surface-sensitive techniques and electrochemical analysis by cyclic voltammetry of the I{sup -}/I{sub 3}{sup -} redox reaction is described.

The 470 Ohm carbon resistor gauge has been used in the stress range up to approximately 4-5 GPa for highly heterogeneous materials and/or divergent flow experiments. The attractiveness of the gauge is due to its rugged nature, simple construction, low cost, reproducibility, and survivability in dynamic events. The associated drawbacks are a long time response to pressure equilibration and gauge resistance hysteresis. In the range below 0.4 GPa, the gauge calibration has been mainly extrapolated into this regime. Because of the need for calibration data within this low stress regime, calibration experiments were performed using a split-Hopkinson bar, drop tower apparatus, and a gas pressure chamber. Since the performance of the gauge at elevated temperatures is a concern, the change in resistance due to heating at atmospheric pressure was also investigated. Details of the various calibration arrangements and the results will be discussed and compared a calibration curve fit to previously published calibration data.

This report provides a side-by-side comparison of the charitable choice provisions of H.R. 7 with those of the 1996 welfare reform law (P.L. 104-193) and of later laws that extended charitable choice rules to the Community Services Block Grant Act (P.L. 105-285) and to substance abuse treatment and prevention services under the Public Health Service Act (P.L 106-310 and P.L. 106-554).

A letter report issued by the General Accounting Office with an abstract that begins "Congress appropriates billions of dollars annually to construct buildings and other facilities for military training and operations. Small business have carried out a significant portion of this work. Congress and small business advocates, however, had become concerned that agencies were combining requirements into larger contracts that small businesses could not win. GAO examined the contract bundling of military construction requirements. GAO determined whether (1) overall data on construction contract awards to small businesses indicated that their ability to compete for contracts had been impaired and (2) selected Department of Defense (DOD) contracting offices had combined construction requirements in ways that hampered small businesses' ability to compete. Overall data on military construction contract awards to small businesses revealed that small businesses are generally continuing to win work and that their ability to compete is not being impaired. The Small Business Administration reviewed and approved of DOD's plan to determine whether the construction work being done could accommodate smaller contractors. Small businesses were able to compete for the remaining contracts."

A letter report issued by the General Accounting Office with an abstract that begins "The Government Performance and Results Act of 1993 requires agencies to produce annual performance reports. GAO reviewed the Department of Transportation's (DOT) performance reports for fiscal years 2000 and 2002 to assess its progress in achieving selected key outcomes in important mission areas. This report (1) assesses the progress DOT has made in accomplishing these outcomes and the strategies the agency has in place to achieve them and (2) compares DOT's fiscal year 2000 performance report and fiscal year 2002 performance plan with the agency's prior year performance report and plan for these outcomes. DOT's consolidated performance report makes it clear that DOT achieved only limited progress in fiscal year 2000 toward achieving the selected outcomes and that the agency directly indicated that its current strategies are not likely to result in achievement of the goals. DOT provided a clear, well-organized discussion of performance goals, measures, and data in both fiscal year 2000 and fiscal year 2002 performance plans."

A letter report issued by the General Accounting Office with an abstract that begins "In 1986, Congress passed the Emergency Medical Treatment and Active Labor Act (EMTALA) in response to reports that some emergency rooms across the country had refused to treat indigent and uninsured patients or had inappropriately transferred them to other hospitals, a practice known as "patient dumping." EMTALA requires hospitals that participate in Medicare to provide a medical screening examination to any person who comes to the emergency department, regardless of the individual's ability to pay. If a hospital determines that the person has an emergency medical condition, it must provide treatment to stabilize the condition or provide for an appropriate transfer to another facility. The regional offices of the Centers for Medicare and Medicaid Services (CMS) are responsible for investigating complaints of alleged violations and forwarding confirmed violations to the Department of Health and Human Services' (HHS) Office of Inspector General (OIG) for possible imposition of civil monetary fines. The medical community has raised concerns that the implementation and enforcement of EMTALA have created burdens for hospitals and physicians, such as overcrowded emergency departments. This report reviews (1) how EMTALA has affected hospital emergency departments and …

This report presents and evaluates options for disposing of depleted uranium in the chemical form of uranium tetrafluoride (UF{sub 4}). Two depleted uranium inventories are considered. One results from the original U.S. Department of Energy (DOE) inventory of 560,000 metric tons (te) of depleted uranium hexafluoride (UF{sub 6}); the other inventory is the original DOE inventory augmented by 145,000 te of depleted UF{sub 6} from the United States Enrichment Corporation. Preconceptual designs are included for three disposal options: disposal in a vault, disposal in an engineered trench, and disposal in a deep mine cavity. The disposal container is taken to be either a 30-gallon drum or a 55-gallon drum. Descriptions of the facilities associated with the three disposal options are provided. Staffing estimates for the construction and operation of the facilities are also provided. Wastes and emissions from the facilities during construction, operation, and maintenance have been estimated. Parametric studies have also been performed on the basis of 25% and 50% of the original inventory.

A chapter report issued by the General Accounting Office with an abstract that begins "To protect human health and safeguard the environment,the Environmental Protection Agency (EPA) regulates pollution generated by sewage treatment plants, power generation plants, chemical manufacturers, and pulp and paper mills. Monitoring is a key component of these efforts. Many of the technologies that are now being used to monitor environmental conditions have been in existence for decades. In recent years, however, several technologies have become available that may offer improved measurement and performance capabilities. This report (1) identifies technologies whose wider use can improve the monitoring of pollutants entering the nation's air and water, (2) determines the extent to which these improved technologies are being used and steps that EPA can take to promote their wider use, and (3) identifies factors that influence the development of new technologies and steps that EPA can take to encourage greater development of new technologies. GAO found that several monitoring technologies exist that can better measure emissions or discharges from stationary air sources, wastewater sources, and nonpoint water sources. These technologies offer advantages over older, more commonly used methods by detecting pollutants at lower levels, reducing monitoring costs, and increasing the …

Laser driven shock measurements have been performed on pre-compressed samples. A diamond anvil cell (DAC) has been used to statically compress water to 1 GPa and then strong shocked with an energetic laser. The use of intense laser irradiation can drive shocks in targets making it possible to study the equation of state (EOS) of samples well into the hundreds of GPQ regime. Generally, such experiments employ a sample initially at normal density and standard pressure. Therefore providing data on the principal Hugoniot. In this experiment the initial state of the sample was varied to provide data off the principal Hugoniot. We report the work that was done on the Vulcan laser and describe a method to achieve off principal Hugoniot data.

The Advanced Technology Development (ATD) Program seeks to aid the development of high-power lithium-ion batteries for hybrid electric vehicles. Nine 18650-size ATD baseline cells were tested under a variety of conditions. The cells consisted of a carbon anode, LiNi{sub 0.8}Co{sub 0.2}O{sub 2} cathode and DEC-EC-LiPF{sub 6} electrolyte, and they were engineered for high-power applications. Selected instrumental techniques such as synchrotron IR microscopy, Raman spectroscopy, scanning electron microscopy, atomic force microscopy, gas chromatography, etc. were used to characterize the anode, cathode, current collectors and electrolyte from these cells. The goal was to identify detrimental processes which lead to battery failure under a high-current cycling regime as well as during storage at elevated temperatures. The diagnostic results suggest that the following factors contribute to the cell power loss: (a) SEI deterioration and non-uniformity on the anode, (b) morphology changes, increase of impedance and phase separation on the cathode, (c) pitting corrosion on the cathode Al current collector, and (d) decomposition of the LiPF{sub 6} salt in the electrolyte at elevated temperature.

The AP-0 Target Hall Collection Lens is a pulsed device which focuses anti-protons just downstream of the Target. Since the angles at which the anti-protons depart the Target can be quite large, a very high focusing strength is required to maximize anti-proton capture into the downstream Debuncher Ring. The current design of the Collection Lens was designed to operate with a focusing gradient of 1,000 T/m. However, multiple failures of early devices resulted in lowering the normal operating gradient to about 750 T/m. At this gradient, the Lens design fares much better, lasting several million pulses, but ultimately still fails. A Finite Element Analysis (FEA) has been performed on this Collection Lens design to help determine the cause and/or nature of the failures. The Collection Lens magnetic field is created by passing high current through a central conductor cylinder. A uniform current distribution through the cylinder will create a tangential or azimuthal magnetic field that varies linearly from zero at the center of the cylinder to a maximum at the outer surface of the cylinder. Anti-proton particles passing through this cylinder (along the longitudinal direction) will see an inward focusing kick back toward the center of the cylinder proportional to …

Correspondence issued by the General Accounting Office with an abstract that begins "Some Lyme disease patients and Lyme disease organizations are concerned that federal agencies and advisors have financial interests that may affect their decisions on the funding of Lyme disease research and the approval of Lyme disease products. These agencies include the Centers for Disease Control (CDC), the National Institutes of Health (NIH), and the Food and Drug Administration (FDA). This report reviews (1) the financial interests that CDC, NIH, and FDA employees and members of advisory committees working on Lyme disease have reported and (2) how these agencies addressed any potential conflicts of interest identified in those reports. GAO found that CDC, NIH, and FDA have generally met the requirements for disclosure and review of financial interests related to Lyme disease. Employees and special government employees (SGE's) working on Lyme disease-related activities have reported financial holdings in, and arrangements with, health sector firms, travel paid for by health sector firms, and patents related to Lyme disease. Program officials and agency officials reviewed the interests of the employees and determined that they did not present conflicts."

A letter report issued by the General Accounting Office with an abstract that begins "The federal government buys about $200 billion worth of goods and services each year. Through its purchasing decisions, the federal government can signal its commitment to preventing pollution, reducing solid waste, increasing recycling, and stimulating markets for environmentally friendly products. The Resource Conservation and Recovery Act of 1976 (RCRA) directs the Environmental Protection Agency (EPA) to identify products made with recycled waste materials or solid waste by-products and to develop guidance for purchasing these products. The act also requires procuring agencies to establish programs for purchasing them. This report examines efforts by federal agencies to (1) implementation of RCRA requirements for procuring products with recycled content and (2) the purchase of environmentally preferable and bio-based products. EPA accelerated its efforts in the 1990s to identify recycled-content products, but the status of agencies' efforts to implement the RCRA purchasing requirements for these products is uncertain. The four major procuring agencies report that, for many reasons, their procurement practices have not changed to increase their purchases of environmentally preferable and bio-based products. One reason for the lack of change is that EPA and the U.S. Department of Agriculture …

A letter report issued by the General Accounting Office with an abstract that begins "GAO audited the fiscal year 2000 financial statement for the Senate Gift Shop Revolving Fund for fiscal year 2000. GAO found (1) the statement is presented fairly in all material respects; (2) although internal control should be improved, the Gift Shop had effective internal controls over financial reporting and compliance with laws and regulations; and (3) no reportable noncompliance with selected provisions of laws and regulations GAO tested."

Goemon is a C++ library that supersedes Tracy 2 written in Pascal. It has been continuously developed at ALS since 1993. This paper describes its design and implementation issues, and applications.

This paper describes the searches for the Higgs boson performed by the CDF and DO collaborations at the Tevatron p{bar p} Collider using the data collected in the 1992-95 run. Searches for standard model Higgs and as well for neutral and charged minimal SUSY Higgs bosons are also presented. No signal has been observed and limits are set for production cross sections.

There are two different horn systems under construction at Fermilab for neutrino beamlines. The NuMI project requires a power supply that operates at 970 V, 205 kA, 2.6 ms, and 0.53 pps. The MiniBooNE project requires a power supply that operates at 5.5 kV, 170 kA, 140 {micro}s and 5 pps. Both require long low inductance connections between the power supply and horn; 60 feet for MiniBooNE and 230 feet for NuMI. This paper discusses several electrical and mechanical design requirements that have been overcome. These include low impedance, radiation hardness, voltage holdoff, clamping for electrical and mechanical connections and humidity and dust control. Measurements of the inductance of the striplines and voltage holdoff will be compared to calculations. The results of some tests will be discussed.
