Management Report: Opportunities for Improvement in the Federal Housing Finance Agency's Internal Controls

Description: Correspondence issued by the Government Accountability Office with an abstract that begins "During our audit of FHFA’s fiscal years 2011 and 2010 financial statements, we identified one internal control issue and a continuing issue related to information systems controls that could adversely affect FHFA’s ability to meet its internal control objectives. We do not consider these issues to represent material weaknesses or significant deficiencies in relation to FHFA’s financial statements. Noneth… more

Gun Control Legislation

Description: This report looks at past gun control legislation and also how recent events (such as the shooting in Tucson, AZ on January 8, 2011 which notably wounded Rep. Gabrielle Giffords) have influenced current legislation. This report concludes with discussion of other salient and recurring gun control issues that have generated past congressional interest.

Concept of Operations for Nuclear Warhead Embedded Sensors

Description: Embedded arms-control-sensors provide a powerful new paradigm for managing compliance with future nuclear weapons treaties, where deployed warhead numbers will be reduced to 1000 or less. The CONOPS (Concept of Operations) for use with these sensors is a practical tool with which one may help define design parameters, including size, power, resolution, communications, and physical structure. How frequently must data be acquired and must a human be present? Will such data be acquired for only st… more

Vibration Model Validation for Linear Collider Detector Platforms

Description: The ILC and CLIC reference designs incorporate reinforced-concrete platforms underneath the detectors so that the two detectors can each be moved onto and off of the beamline in a Push-Pull configuration. These platforms could potentially amplify ground vibrations, which would reduce luminosity. In this paper we compare vibration models to experimental data on reinforced concrete structures, estimate the impact on luminosity, and summarize implications for the design of a reinforced concrete pl… more

FACET: SLAC’s New User Facility

Description: FACET (Facility for Advanced Accelerator Experimental Tests) is a new User Facility at SLAC National Accelerator Laboratory. The first User Run started in spring 2012 with 20 GeV, 3 nC electron beams. The facility is designed to provide short (20 {micro}m) bunches and small (20 {micro}m wide) spot sizes, producing uniquely high power beams. FACET supports studies from many fields but in particular those of Plasma Wakefield Acceleration and Dielectric Wakefield Acceleration. The creation of driv… more

SRNL PHASE 1 ASSESSMENT OF THE WAC/DQO AND UNIT OPERATIONS FOR THE WTP WASTE QUALIFICATION PROGRAM

Description: The Hanford Tank Waste Treatment and Immobilization Plant (WTP) is currently transitioning its emphasis from a design and construction phase toward start-up and commissioning. With this transition, the WTP Project has initiated more detailed assessments of the requirements related to actual processing of the Hanford Site tank waste. One particular area of interest is the waste qualification program to be implemented to support the WTP. Given the successful implementation of similar waste qualif… more

Coexistence of Two- and Three-dimensional Shubnikov-de Haas Oscillations in Ar^+ -irradiated KTaO_3

Description: We report the electron doping in the surface vicinity of KTaO{sub 3} by inducing oxygen-vacancies via Ar{sup +}-irradiation. The doped electrons have high mobility (> 10{sup 4} cm{sup 2}/Vs) at low temperatures, and exhibit Shubnikov-de Haas oscillations with both two- and three-dimensional components. A disparity of the extracted in-plane effective mass, compared to the bulk values, suggests mixing of the orbital characters. Our observations demonstrate that Ar{sup +}-irradiation serves as … more

Precision Magnet Measurements for X-Band Accelerator Quadrupole Triplets

Description: An X-band test station is being developed at LLNL to investigate accelerator optimization for future upgrades to mono-energetic gamma-ray (MEGa-Ray) technology at LLNL. Beamline magnets will include an emittance compensation solenoid, windowpane steering dipoles, and quadrupole magnets. Demanding tolerances have been placed on the alignment of these magnets, which directly affects the electron bunch beam quality. A magnet mapping system has been established at LLNL in order to ensure the delive… more

RF Gun Photo cathode Research at SLAC

Description: LCLS is presently operating with a third copper photocathode in the original rf gun, with a quantum efficiency (QE) of {approx}1 x 10{sup -4} and projected emittance {gamma}{var_epsilon}{sub x,y} = 0.45 {micro}m at 250 pC bunch charge. The spare LCLS gun is installed in the SLAC Accelerator Structure Test Area (ASTA), fully processed to high rf power. As part of a wider photocathode R and D program, a UV laser system and additional gun diagnostics are being installed at ASTA to measure QE, QE l… more

Iraq: Politics, Governance, and Human Rights

Description: This report discusses Iraq: Politics, Governance, and Human Rights. Relations among major political factions have worsened substantially since late 2011, threatening Iraq's stability and the perception of the achievements of the long U.S. intervention in Iraq. Sunni Arabs, always fearful that Prime Minister Nuri al-Maliki would seek unchallenged power for Shiite factions allied with him, accuse him of an outright power grab as he seeks to purge the highest-ranking Sunni Arabs from government an… more
