Homeland Security: Coast Guard Operations - Background and Issues for Congress
This report discusses the Coast Guard, which is the lead federal agency for maritime homeland security. For FY2007, the Coast Guard is requesting a total of about $4.5 billion for missions defined in The Homeland Security Act of 2002 (P.L. 107-296) as the Coast Guard’s homeland security missions. This equates to about 54% of the Coast Guard’s total requested FY2007 budget. The Coast Guard’s homeland security operations pose several potential issues for Congress, including adequacy of Coast Guard resources for performing both homeland security and non-homeland security missions, and Coast Guard coordination with other agencies involved in maritime homeland security.

Measurement of cross sections for alpha-induced reactions on 197Au and thick-target yields for the ((alpha),(gamma)) process on 64Zn and 63Cu
We have measured the cross sections for the {sup 197}Au({alpha},{gamma}){sup 201}Tl and {sup 197}Au({alpha},2n){sup 199}Tl reactions in the 17.9- to 23.9-MeV energy range, and {sup 197}Au({alpha},n){sup 200}Tl reaction in the 13.4- to 23.9-MeV energy range using an activation technique. Thick-target yields for the {sup 64}Zn({alpha},{gamma}){sup 68}Ge (7- to 14-MeV) and {sup 63}Cu({alpha},{gamma}){sup 67}Ga (7-MeV) reactions were measured. For all measurements, natural elements were bombarded with He{sup +} beams from the 88'' Cyclotron at the Lawrence Berkeley National Laboratory (LBNL). Irradiated samples were counted using a g-spectrometry system at LBNL's Low Background Facility. Measured {sup 197}Au({alpha},{gamma}){sup 201}Tl cross-sections were compared with the NON-SMOKER theoretical values. The thick-target yields for the {sup 64}Zn({alpha},{gamma}){sup 68}Ge and {sup 63}Cu({alpha},{gamma}){sup 67}Ga reactions are also compared with the theoretical yield, calculated numerically using the energy dependent NON-SMOKER cross section data. In both cases, measured values are found to follow a trend of overlapping the predicted value near the alpha nucleus barrier height and fall below with a slowly widening difference between them in the sub barrier energy points.

MOSSFRAC: An anisotropic 3D fracture model
Despite the intense effort for nearly half a century to construct detailed numerical models of plastic flow and plastic damage accumulation, models for describing fracture, an equally important damage mechanism still cannot describe basic fracture phenomena. Typical fracture models set the stress tensor to zero for tensile fracture and set the deviatoric stress tensor to zero for compressive fracture. One consequence is that the simple case of the tensile fracture of a cylinder under combined compressive radial and tensile axial loads is not modeled correctly. The experimental result is a cylinder that can support compressive radial loads, but no axial load, whereas, the typical numerical result is a cylinder with all stresses equal to zero. This incorrect modeling of fracture locally also has a global effect, because material that is fracturing produces stress release waves, which propagate from the fracture and influence the surrounding material. Consequently, it would be useful to have a model that can describe the stress relief and the resulting anisotropy due to fracture. MOSSFRAC is a material model that simulates three-dimensional tensile and shear fracture in initially isotropic elastic-plastic materials, although its framework is also amenable to initially anisotropic materials. It differs from other models by …

Navy DDG-1000 (DD(X)), CG(X), and LCS Ship Acquisition Programs: Oversight Issues and Options for Congress
The Navy wants to procure three new classes of surface combatants -- the DDG-1000 (formerly DD(X)) destroyer, the CG(X) cruiser, and a smaller surface combatant called the Littoral Combat Ship (LCS). The Navy wants to procure 7 DDG-1000s, 19 CG(X)s, and 55 LCSs. The Senate Appropriations Committee, in its report (S.Rept. 109-292 of July 25, 2006) on H.R. 5631, recommends approving the Navy's request for FY2007 procurement funding for the first two DDG-1000s and increasing the Navy's request for FY2007 DDG-1000 research and development funding by a net $1 million. This CRS report explains the above as well as other budgetary recommendations made by the Senate Appropriations Committee.

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress
The Navy in February 2006 proposed to maintain in coming years a fleet of 313 ships, including, among other things, 11 aircraft carriers, 48 attack submarines (SSNs), 88 cruisers and destroyers, 55 Littoral Combat Ships (LCSs), 31 amphibious ships, and a Maritime Prepositioning Force (Future), or MPF(F), squadron with 12 new-construction amphibious and sealift-type ships. The Navy says that for its shipbuilding plans to be affordable and executable, the Navy needs to control certain non-shipbuilding expenditures and build ships within estimated costs. The Navy's shipbuilding plans raise potential issues regarding the shipbuilding industrial base, particularly in the areas of the submarine design and engineering base, and the surface combatant construction base.

In conjunction with this proposed 313-ship fleet, the Navy submitted a 5-year (FY2007-FY2011) shipbuilding plan as part of the FY2007-FY2011 Future Years Defense Plan (FYDP), and a 30- year (FY2007-FY2036) shipbuilding plan that the Navy is required by law to submit each year.

NEUTRON ACTIVATION ANALYSIS APPLICATIONS AT THE SAVANNAH RIVER SITE USING AN ISOTOPIC NEUTRON SOURCE
NAA using {sup 252}Cf is used to address important areas of applied interest at SRS. Sensitivity needs for many of the applications are not severe; analyses are accomplished using a 21 mg {sup 252}Cf NAA facility. Because NAA allows analysis of bulk samples, it offers strong advantages for samples in difficult-to-digest matrices when its sensitivity is sufficient. Following radiochemical separation with stable carrier addition, chemical yields for a number methods are determined by neutron activation of the stable carrier. In some of the cases where no suitable stable carriers exist, the source has been used to generate radioactive tracers to yield separations.

Niobium Oxide-Metal Based Seals for High Temperature Applications
The present final report describes technical progress made in regards to evaluating niobium oxide/alumina as a high temperature seal material. Fabrication and characterization of specimens comprising niobium oxide and alumina composites of various compositions was performed. The goal was to identify regions where a glass formed. There were no experimental conditions where a glassy phase was unequivocally identified. However, the results led to the formation of an interesting class of fibrous composites which may have applications where high compliance and high toughness are needed. It is clear that vapor phase sintering is an active mass transport mechanism in Nb{sub 2}O{sub 5}-Al{sub 2}O{sub 3} composites (Figure 1), and it may be possible to design porous materials by utilizing vapor phase sintering. The compositions evaluated in the present work are 52, 60, 73, 82 and 95 mol. % Nb{sub 2}O{sub 5} with the remainder Al{sub 2}O{sub 3}. These were chosen so that some eutectic composition was present during cooling, in an attempt to encourage glass formation. However, the presence of large, elongated crystals, both in the slow cool and the quench experiments indicates that the driving force for crystallization is very high. Several joints were formed between high purity alumina with two …

The Radiation Dose Measurement System for the BaBar Electromagnetic Calorimeter
An array of 116 p-channel radiation sensitive MOSFET transistors (RadFETs) has been operational for the past 6 years at the BaBar experiment at the PEP-II asymmetric B-Factory at the Stanford Linear Accelerator Center (SLAC). This system maps the integrated dose absorbed by different regions of the Electromagnetic Calorimeter (EMC) during the running of the experiment. We report on the design and implementation of the system and finally, the performance of the monitoring system during the last 6 years of BaBar data-taking.
