A 15-T Pulsed Solenoid for a High-Power Target Experiment

Description: The MERIT experiment, to be run at CERN in 2007, is a proof-of-principle test for a target system that converts a 4-MW proton beam into a high-intensity muon beam for either a neutrino factory complex or a muon collider. The target system is based on a free mercury jet that intercepts an intense proton beam inside a 15-T solenoidal magnetic field. Here, we describe the design and initial performance of the 15-T, liquid-nitrogen-precooled, copper solenoid magnet.

527 Organizations: How the Differences in Tax and Election Laws Permit Certain Organizations to Engage in Issue Advocacy without Public Disclosure and Proposals for Change

Description: This report compares the tax and election laws relating to political organizations and political committees in an attempt to highlight the differences between them, and discusses some of the proposals in the 106th Congress to require additional reporting by organizations engaging in political activities. This report does not address the taxation of other tax-exempt organizations making political expenditures taxable under IRC § 527. The report will be updated as new proposals are reported.

Acceleration of Polarized Protons in the AGS With Two Helical Partial Snakes.

Description: Acceleration of polarized protons in the energy range of 5 to 25 GeV is particularly difficult: the depolarizing resonances are strong enough to cause significant depolarization but full Siberian snakes cause intolerably large orbit excursions and are not feasible in the AGS since straight sections are too short. Recently, two helical partial snakes with double pitch design have been built and installed in the AGS. With careful setup of optics at injection and along the ramp, this combination c… more

Acenaphthene solvents for use in Building 313 Frost Test operation

Description: Acenaphtheno is a low-melting organic compound, C{sub 10}H{sub 6}(CH{sub 2}){sub 2}, used as a temperature indicating coating for slugs tested in the Frost Test induction coil. In preparation for this test, slugs are coated by spraying a 12 to 24 per cent by weight solution of acenaphthene in a high vapor pressure solvent on the rotating slug. The solvent evaporate leaving a thin, adherent coating of acenaphthene. This process is completely described in reference 1. To be entirely satisfactory … more

AFCI-2.0 Library of Neutron Cross Section Covariances

Description: Neutron cross section covariance library has been under development by BNL-LANL collaborative effort over the last three years. The primary purpose of the library is to provide covariances for the Advanced Fuel Cycle Initiative (AFCI) data adjustment project, which is focusing on the needs of fast advanced burner reactors. The covariances refer to central values given in the 2006 release of the U.S. neutron evaluated library ENDF/B-VII. The preliminary version (AFCI-2.0beta) has been completed … more

Afghanistan: Politics, Government Formation and Performance

Description: The Afghan central government's limited writ and widespread official corruption are helping sustain a Taliban insurgency, and have fed pessimism about the Afghanistan stabilization effort. This report discusses the current tumultuous political state of Afghanistan, focusing particularly on Afghan President Hamid Karzai and his struggle with the Taliban terrorist group. This report also discusses Afghanistan's relationship with the U.S. with regard to these struggles, and describes various U.S. … more

Age Strengthening of Gray Cast Iron Phase III

Description: The primary objective of this research is to identify the age strengthening mechanism in gray and ductile cast iron, and to quantify the parameters that control it. It is also to contribute to a new predictive model for gray and ductile iron strength and hardness. This work shows that age strengthening occurs on a sigmoidal-logarithmic scale in gray and ductile cast irons, to a statistically significant extent. This is similar to Avrami-Johnson-Mehl kinetics for phase transformations in metals.… more

AGING AND SURVEILLANCE OF VITON GLT O-RINGS IN MODEL 9975 SHIPPING PACKAGES

Description: Radioactive material packages (DOT Type B) such as the Model 9975 are used to transport Pu-bearing materials. The 9975 package provides double payload containment via nested stainless steel primary (PCV) and secondary (SCV) containment vessels. The containment vessels are closed by a conical plug sealed with dual O-rings (Figure 1) made of Parker Seals compound V0835-75, based on Viton{reg_sign} GLT fluoroelastomer. The outer O-ring is credited as being leaktight per ANSI N14.5 with a leak rate… more

Agricultural Disaster Assistance

Description: This report discusses several programs offered by the U.S. Department of Agriculture (USDA) to help farmers recover financially from natural disasters, including drought and floods. All the programs have permanent authorization, and only one requires a federal disaster designation (the emergency loan program). Most programs receive funding amounts that are "such sums as necessary" and are not subject to annual discretionary appropriations.

ALE3D Simulation of Heating and Violence in a Fast Cookoff Experiment with LX-10

Description: We performed a computational and experimental analysis of fast cookoff of LX-10 (94.7% HMX, 5.3% Viton A) confined in a 2 kbar steel tube with reinforced end caps. A Scaled-Thermal-Explosion-eXperiment (STEX) was completed in which three radiant heaters were used to heat the vessel until ignition, resulting in a moderately violent explosion after 20.4 minutes. Thermocouple measurements showed tube temperatures as high as 340 C at ignition and LX-10 surface temperatures as high as 279 C, which i… more

Altitude performance investigation of a high-temperature afterburner

Description: From Introduction: "In response to the ever-increasing need for high thrust augmentation, an investigation was conducted that had as its primary objective the attainment of maximum exhaust-gas temperature and thrust (ref. 1). The investigation reported herein was therefore conducted to ascertain the operational limits of the most promising high-temperature afterburner design of reference 1 and to determine its performance over a wind range of flight conditions."

Altitude Wind Tunnel Investigation of High-Temperature Afterburners

Description: From Introduction: "During previous investigations of afterburning conducted at the NACA Lewis laboratory (references 1 to 4, for example), the objective of obtaining high exhaust-gas temperatures and, consequently, maximum thrust augmentation was compromised to some extent in order to alleviate the problem of afterburner shell cooling. The primary objective of the investigation reported herein was therefore the attainment of maximum exhaust-gas temperature imposed by the cooling techniques pre… more

Analysis of a flow metering device for low-quality steam-water flows. Final report

Description: The goal of this project is to investigate the potential of the meter configuration consisting of a sharp-edged contraction section followed by an extended length of constant area duct and finally a diffuser section for pressure recovery. This and two other configurations were tested. These configurations and the reasons underlying their selection are described and discussed. It is concluded that Murdock's correlation for steam/water flow through orifices and sudden contraction sections at low … more

Analysis of a High-Efficiency Natural Gas-Assisted Steam Electrolyzer for Hydrogen Production

Description: This paper presents a description and analysis of a high-efficiency hydrogen production system. The main component of the system is a novel steam electrolyzer. In conventional electrolyzers, oxygen produced from electrolysis is usually released into the environment. In this design, natural gas is used to react with the oxygen produced in the electrolysis, reducing reduce the chemical potential difference across the electrolyzer, thus minimizing electricity consumption. The oxygen produced from … more

Analysis of Availability and Reliability in Rhic Operations.

Description: RHIC has been successfully operated for 5 years as a collider for different species, ranging from heavy ions including gold and copper, to polarized protons. We present a critical analysis of reliability data for RHIC that not only identifies the principal factors limiting availability but also evaluates critical choices at design times and assess their impact on present machine performance. RHIC availability data are typical when compared to similar high-energy colliders. The critical analysis… more
