A 15-T Pulsed Solenoid for a High-Power Target Experiment (open access)

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

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.

Acceleration of Polarized Protons in the AGS With Two Helical Partial Snakes. (open access)

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

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 can eliminate the intrinsic and imperfection depolarizing resonances encountered during acceleration. This paper presents the accelerator setup and preliminary results.

Acenaphthene solvents for use in Building 313 Frost Test operation (open access)

Acenaphthene solvents for use in Building 313 Frost Test operation

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 for this use, a solvent must satisfy four requirements. High vapor pressure -- rapid evaporation. Non-flammability. Low toxicity. Carbon tetrachloride, the solvent used at percent, is operationally satisfactory but undersirable because of its toxicity. The purpose of this test is to investigate the suitability of various solvents as substituted for carbon tetrachloride.

AFCI-2.0 Library of Neutron Cross Section Covariances (open access)

AFCI-2.0 Library of Neutron Cross Section Covariances

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 in October 2010 and made available to the users for comments. In the final 2.0 release, covariances for a few materials were updated, in particular new LANL evaluations for {sup 238,240}Pu and {sup 241}Am were adopted. BNL was responsible for covariances for structural materials and fission products, management of the library and coordination of the work, while LANL was in charge of covariances for light nuclei and for actinides.

Age Strengthening of Gray Cast Iron Phase III (open access)

Age Strengthening of Gray Cast Iron Phase III

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. It occurs in both cupola-melted iron and induction melted iron. However, it does not happen in all compositions. We have developed some understanding of the process. Data suggests that nitrogen and nitride-forming trace elements have a significant role in the process, but that is yet not fully characterized. Also, the time dependence of the bulk hardness and strength increase, the nano-scale precipitation evidence from neutron scattering, differential scanning calorimetry results and matrix micro-hardness increase in ferrite all indicate that age strengthening occurs by a precipitation or pre-precipitate cluster formation mechanism.

AGING AND SURVEILLANCE OF VITON GLT O-RINGS IN MODEL 9975 SHIPPING PACKAGES (open access)

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

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 of <1E-07 ref cc/sec. The 9975 package is being used for interim storage in the K-Area Material Storage (KAMS) facility at the Savannah River Site. The aging performance of the O-rings is being studied to provide the storage facility a technical basis for service life prediction and safety analysis.

Agricultural Disaster Assistance

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 (open access)

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

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 is near the melting point of HMX. Three micro-power radar systems were used to measure mean fragment velocities of 840 m/s. Photonics Doppler Velocimeters (PDVs) showed a rapid acceleration of fragments over 80 {micro}s. A one-dimensional ALE3D cookoff model at the vessel midplane was used to simulate the heating, thermal expansion, LX-10 decomposition composition, and closing of the gap between the HE (High Explosive) and vessel wall. Although the ALE3D simulation terminated before ignition, the model provided a good representation of heat transfer through the case and across the dynamic gap to the explosive.

Altitude performance investigation of a high-temperature afterburner

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

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 previously used, a secondary flow of cooling air was provided around the afterburner shell."
