Development of passive electronic components for instrumentation of improved geothermal logging tools and components. Annual progress report
Short term objectives for well-logging instrumentation are circuits which can operate at temperatures in the range 275/sup 0/C to 350/sup 0/C; the medium term goal is operation up to 500/sup 0/C, and the long term goal is to achieve operation at 1000/sup 0/C. It is apparent that useful electronic circuits will require the combination of both passive components and active devices. In order to meet the compatibility requirements, the basic technology which has been selected in this project is the chemical vapor deposition of metal interconnections, resistor material, dielectric material and passivating material. It is to be emphasized that this is a thin-film, not thick-film, technology which is compatible with the processing methods used in fabricating either semiconductor or integrated thermionic devices, and produces components which are electrically compatible with those devices. The investigation in this project is primarily directed toward tungsten metallization, tungsten-silicon resistors, and silicon nitride dielectric and passivation.

In Vivo Gamma Lung Measurements--a Mathematical Model
A low-background facility is described for rneasuring lung burdens of U, Th, and other nuclides in vivo. Problems associated with this method of radiation measurement are discussed. A mathennatical, computer-oriented simulation was devised to gain insight into the relation of the net observed radiation spectrum to the burden of radioactivity in the body or its organs. Chest cavities for persons of three sizes were synthesized in a three-coordinate space comprised of one-inch cubes and including a 9-in.-diameter crystal detector. Data, describing the tissue composition of each cube in the body and the characteristic radiation attenuation for each tissue-type, were coded for use with a program on a high-speed digital computer. Efficiencies for measuring radiation emitted by numerous point sources of enriched uranium were calculated. Data on in vivo measurement efficiency were obtained assuming uniform distribution of radioactive material throughout the lungs and also for nonuniform deposits. The effects of individual size and geometry, and of detector position on the measurement efficiency were determined for these twvo categories and radiation flux distributions on the detector face were computed in some cases. Data are appended and a flow diagram of the computer program is included. (C.H.)

ORR Operations for Period April 1960-April 1961
Conversion of the ORR from 20 to 30 Mw operating level was achieved during July 1960 after a scheduled shutdown for completion of a new cooling system. Operating time reached a high of 82% during the last quarter of 1960. The first quarter of 1961 showed an operating time of 80% despite 2 shutdowns and some additional down time to repair mechanisms associated with the shim rods. Changes were made in the south engineering test facility for GCR test loops. Detailed data taken from quarterly operational reports are included. (J.R.D.)

Review of single transient oscillographic recorders with gigahertz bandwidth
In laser driven inertial confinement fusion research, at Livermore, we are diagnosing many phenomena that occur in a time frame that exceeds the capabilities of even the most advanced, present day oscillographic recording instruments. Many of the by-products of the interaction between the laser beam and fuel pellet are monitored to determine the specifics of the fusion process. By the use of appropriate detectors, we convert the information contained in the radiated by-products to electrical signals which are recorded on high bandwidth oscillographic recorders. Our present range of recording capabilities for one x-ray diagnostic measurement in use at Livermore is shown. A commonly used configuration consists of an XRD-31 x-ray detector connected to a direct access Tektronix R7912 transient digitizer using 1/2 in. diameter air dielectric coaxial cable. This configuration gives a system fwhm of approximately 335 ps. Our premier configuration, on the other hand, consists of an improved response detector and a French Thomson-CSF TSN-660 oscilloscope with a shorter length of coaxial cable (typically 20 feet). The system fwhm in this case is less than 120 ps which is our fastest oscillographic recording system at the present time.

Inelastic Strong Interactions at High Energies. [Cross Sections, Field Theory]
A method permitting the calculation of inclusive and semi-inclusive cross sections at high energies starting from an arbitrary field theory was worked out. The method relies on a functional integral representation of the generating functional of inclusive cross sections and on the use of semiclassical methods. The inclusive cross section is proportional to the absolute square of the Fourier transform of a special soliton solution of the classical field equations in zeroth order semi-classical approximation. A conserved topological quantum number that has a nonzero value for the soliton solution was found. Future research to be performed in this field under the contract is described including applications to various field theories and the exploration of connections with Reggeon field theory.

Position and profile of a multiampere proton beam
The spacial profile of a bunched or unbunched proton beam may be found by using a highly collimated molecular beam of N/sub 2/. A certain fraction of the molecular N/sub 2/ will be ionized as it crosses the proton beam. By measuring the N/sub 2//sup +/ current as a function of theta the cross section of the beam is directly obtained. As an example, a 10 A proton beam of diameter 1 mm is considered.

Plutonium Residue Recovery (PuRR) project quarterly progress report, April--June 1989
A material-balance flowsheet for ash-heel processing has been prepared. The major process features are (1) reduction of Pu into a calcium-zinc alloy and selective electrolytic recovery of the Pu from the alloy, (2) removal of americium as a waste, (3) concentration of nontransuranic tramp elements in a zinc waste, (4) removal of oxygen and recovery of calcium by electrolysis of CaO, and (5) zinc recycle by evaporation. Based on this idealized flowsheet, the mass of solid waste is only 62% of that of the original residue. This is accomplished by recycling virtually all the reagents and discarding the oxygen as CO and CO{sub 2}. The pyrochemical recovery of Pu from incinerator ash heel from the Rocky Flats Plant was investigated. During this period, zinc-calcium alloys were used to reduce the PuC{sub 2} in the ash. Reduction of ash heel has been attempted with zinc-calcium alloys containing 2, 6, and 10 wt% calcium after the reduction. These resulted in extractions of 95%, 97%, and 99.5%, respectively, of the Pu from the salt. Following exposure of the reduction alloy to a ZnCl{sub 2}-bearing salt, the Pu was removed effectively from the alloy; however, the Pu recovered in the salt did not complete …

U.S. Department of Agriculture: Internal Control Would Improve Accountability for Certain Centrally Provided (Greenbook) Programs
A letter report issued by the Government Accountability Office with an abstract that begins "The Senate report accompanying the U.S. Department of Agriculture's (USDA) fiscal year 2008 appropriations expressed concern that USDA's Greenbook charges--the transfer of funds authority USDA used to charge the appropriations accounts of its agencies and staff offices for programs to centrally provide certain services--had grown excessively. USDA's Office of the Chief Financial Officer (OCFO) oversees Greenbook charges. The report directed GAO to review these charges and USDA to report on them. This report identifies the agencies and offices assessed Greenbook charges, the amounts of the charges, and the programs supported by Greenbook charges for fiscal years 1999 through 2009. It also (1) assesses how USDA selected programs and monitored Greenbook charges and (2) describes the benefits of the programs, as reported by USDA. GAO reviewed and assessed USDA budget and program documents and discussed processes with officials."

Indian Issues: BLM's Program for Issuing Individual Indian Allotments on Public Lands Is No Longer Viable
Correspondence issued by the Government Accountability Office with an abstract that begins "Beginning in the late nineteenth century the federal government began an effort to assimilate Indians by transferring them from communal tribal existence to individual land ownership. The Act of February 8, 1887, commonly referred to as the General Allotment Act, initiated the federal government's Indian allotment policy. The act authorized the President to allot parcels of land to individual Indians--generally in sizes of 40, 80, or 160 acres--on Indian reservations and on public lands. The act was implemented by the Department of the Interior's (Interior) Bureau of Indian Affairs (BIA) and Bureau of Land Management (BLM). Under this authority, BIA issued millions of acres of individual allotments on Indian reservations, and BLM issued thousands of acres of individual Indian allotments on public lands. However, in 1934, the Indian Reorganization Act largely reversed the federal government's Indian allotment policy and replaced it with a policy that encouraged tribal self-governance. Section 5 of the Indian Reorganization Act also provided the Secretary of the Interior new authority to acquire land, on and off reservations, on behalf of federally recognized tribes or their members. While the Indian Reorganization Act ended BIA's authority …

Managing Sensitive Information: DOJ Needs a More Complete Staffing Strategy for Managing Classified Information and a Set of Internal Controls for Other Sensitive Information
A letter report issued by the Government Accountability Office with an abstract that begins "The September 11 attacks showed that agencies must balance the need to protect and share sensitive information to prevent future attacks. Agencies classify this information or designate it sensitive but unclassified to protect and limit access to it. The National Archives' Information Security Oversight Office (ISOO) assesses agencies' classification management programs, and in July 2004 and April 2005 recommended changes to correct problems at the Justice Department (DOJ) and Federal Bureau of Investigation (FBI). GAO was asked to examine (1) DOJ's and FBI's progress in implementing the recommendations and (2) the management controls DOJ components have to ensure the proper use of sensitive but unclassified designations. GAO reviewed ISOO's reports and agency documentation on changes implemented and controls in place, and interviewed security program managers at DOJ, its components, and ISOO to examine these issues."

Homeland Security: Opportunities Exist to Enhance Collaboration at 24/7 Operations Centers Staffed by Multiple DHS Agencies
A letter report issued by the Government Accountability Office with an abstract that begins "Because terrorists do not operate on a 9-5 schedule, the Department of Homeland Security (DHS) and its operational components have established information gathering and analysis centers that conduct activities 24 hours a day, 7 days a week, 365 days a year. Staff at these operations centers work to help detect, deter, and prevent terrorist acts. DHS has determined that out of 25 operations centers, four require higher levels of collaboration that can only be provided by personnel from multiple DHS agencies, and other federal, and sometimes state and local, agencies. For these four multi-agency operations centers, this report (1) describes their missions, products, functions, and customers and (2) assesses the extent to which DHS efforts to promote collaboration among the multiple agencies responsible for the centers reflect key practices for enhancing and sustaining collaborative efforts. To do so, GAO visited operations centers, reviewed data and reports from the centers, and interviewed center and other DHS officials."

Adoption Tax Credit: IRS Can Reduce Audits and Refund Delays
A letter report issued by the Government Accountability Office with an abstract that begins "The federal adoption tax credit, established in 1996, was amended in 2010. These amendments included making the credit refundable (meaning taxpayers could receive payments in excess of their tax liability) and increasing the maximum allowable credit to $13,170 of qualified adoption expenses for tax year 2010. As of August 20, 2011, taxpayers filed just under 100,000 returns, claiming about $1.2 billion in adoption credits. Following these changes, the Internal Revenue Service (IRS) developed a strategy for processing adoption credit claims. GAO was asked to (1) describe IRS's strategy for ensuring compliance with the adoption credit for the 2011 filing season, (2) assess IRS's related communication with taxpayers and stakeholders, and (3) assess its processing and audit of claims. To conduct its analysis, GAO analyzed IRS data and documents, interviewed IRS officials, observed IRS examiners, and interviewed other stakeholders."

Juvenile Justice: Technical Assistance and Better Defined Evaluation Plans Will Help Girls' Delinquency Programs
Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses issues related to girls' delinquency--a topic that has attracted the attention of federal, state, and local policymakers for more than a decade as girls have increasingly become involved in the juvenile justice system. For example, from 1995 through 2005, delinquency caseloads for girls in juvenile justice courts nationwide increased 15 percent while boys' caseloads decreased by 12 percent. More recently, in 2007, 29 percent of juvenile arrests--about 641,000 arrests--involved girls, who accounted for 17 percent of juvenile violent crime arrests and 35 percent of juvenile property crime arrests. Further, research on girls has highlighted that delinquent girls have higher rates of mental health problems than delinquent boys, receive fewer special services, and are more likely to abandon treatment programs. The Office of Juvenile Justice and Delinquency Prevention (OJJDP) is the Department of Justice (DOJ) office charged with providing national leadership, coordination, and resources to prevent and respond to juvenile delinquency and victimization. OJJDP supports states and communities in their efforts to develop and implement effective programs to, among other things, prevent delinquency and intervene after a juvenile has offended. For example, from fiscal years 2007 …

Military Personnel: DFAS Has Not Met All Information Technology Requirements for Its New Pay System
Correspondence issued by the General Accounting Office with an abstract that begins "In early January 2003, we initiated a review of the Defense Integrated Military Human Resource System (DIMHRS) to get an understanding of the program, its goals, its present status, and the problems it is designed to resolve. During this review, we became aware that in April 2003 the Department of Defense (DOD) authorized the Defense Finance and Accounting Service (DFAS) to initiate a pilot project to demonstrate its ability to develop an interim military pay system, called Forward Compatible Military Pay, before DIMHRS is fully operational. DFAS maintains that an interim system should be developed as soon as possible for two reasons: (1) the planned personnel and pay system that DOD is currently developing as part of the larger DIMHRS will be implemented later than its projected target date of December 2006 and (2) the current military pay system--the Defense Joint Military Pay System--is aging, unresponsive, and fragile and has become a major impediment to efficient and high quality customer service. It is estimated that the Forward Compatible Military Pay system could be operational by March 2006 at a design and development cost ranging from about $17 million …

VA Disability Benefits: Routine Monitoring of Disability Decisions Could Improve Consistency
Testimony issued by the Government Accountability Office with an abstract that begins "The House Subcommittee on Disability Assistance and Memorial Affairs asked GAO to discuss its work on the consistency of disability compensation claims decisions of the Department of Veterans Affairs (VA). GAO has reported wide state-to-state variations in average compensation payments per disabled veteran, raising questions about decisional consistency. In 2003, GAO designated VA's disability programs, along with other federal disability programs, as high risk, in part because of concerns about decisional consistency. Illustrating this issue, GAO reported that inadequate information from VA medical centers on joint and spine impairments contributed to inconsistent regional office disability decisions."

Intragovernmental Revolving Funds: NIST's Interagency Agreements and Workload Require Management Attention
A letter report issued by the Government Accountability Office with an abstract that begins "GAO previously found that a significant portion of the National Institute of Standards and Technology's (NIST) working capital fund contained a growing carryover balance. Almost all of the fund's resources come from appropriations advanced from federal clients for NIST's technical services through interagency agreements. Monitoring and tracking key information about agreements and the funds advanced for them is critical for both NIST and its clients to make well-informed budget decisions, comply with applicable fiscal laws and internal controls, and ensure the proper use of federal funds. GAO was asked to review (1) the factors contributing to the working capital fund's carryover balance and (2) NIST's processes for managing its interagency agreements and workload. To do so, GAO reviewed laws and fiscal requirements, analyzed NIST budget data and policies related to its interagency agreements, analyzed a random sample of agreements, and interviewed NIST officials."
