Human Capital: HHS and EPA Can Improve Practices Under Special Hiring Authorities

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Health and Human Services’ (HHS) use of special hiring authorities under 42 U.S.C. §§ 209(f) and (g) has increased in recent years. Nearly all HHS Title 42 employees work in one of three HHS operating divisions: the National Institutes of Health (NIH), the Food and Drug Administration (FDA), and the Centers for Disease Control and Prevention (CDC). Title 42 employees at HHS serve in a variety of areas, including scientific and medical research support and in senior, director-level leadership positions. At NIH, one-quarter of all employees, and 44 percent of its researchers and clinical practitioners, were Title 42 appointees. HHS reported that Title 42 enables the agency to quickly fill knowledge gaps so medical research can progress and to respond to medical emergencies. HHS further reported Title 42 provides the compensation flexibility to compete with the private sector. In 2010, 1,461 HHS Title 42 employees earned salaries over Executive Level IV ($155,500 in 2010). HHS does not have reliable data to manage and provide oversight of its use of Title 42 because the section authority used to hire Title 42 employees is not …

Electronic Warfare: DOD Actions Needed to Strengthen Management and Oversight (open access)

Electronic Warfare: DOD Actions Needed to Strengthen Management and Oversight

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) developed an electronic warfare strategy, but it only partially addressed key characteristics that GAO identified in prior work as desirable for a national or defense strategy. The National Defense Authorization Act for Fiscal Year 2010 requires DOD to submit to the congressional defense committees an annual report on DOD’s electronic warfare strategy for each of fiscal years 2011 through 2015. DOD issued its fiscal year 2011 and 2012 strategy reports to Congress in October 2010 and November 2011, respectively. GAO found that DOD’s reports addressed two key characteristics: (1) purpose, scope, and methodology and (2) problem definition and risk assessment. However, DOD only partially addressed four other key characteristics of a strategy, including (1) resources, investments, and risk management and (2) organizational roles, responsibilities, and coordination. For example, the reports identified mechanisms that could foster coordination across the department and identified some investment areas, but did not fully identify implementing parties, delineate roles and responsibilities for managing electronic warfare across the department, or link resources and investments to key activities. Such characteristics can help shape policies, programs, priorities, resource allocation, and …

Cavity Beam Position Monitor System for ATF2 (open access)

Cavity Beam Position Monitor System for ATF2

The Accelerator Test Facility 2 (ATF2) in KEK, Japan, is a prototype scaled demonstrator system for the final focus required for a future high energy lepton linear collider. The ATF2 beam-line is instrumented with a total of 38 C and S band resonant cavity beam position monitors (CBPM) with associated mixer electronics and digitizers. The current status of the BPM system is described, with a focus on operational techniques and performance. The ATF2 C-band system is performing well, with individual CBPM resolution approaching or at the design resolution of 50 nm. The changes in the CBPM calibration observed over three weeks can probably be attributed to thermal effects on the mixer electronics systems. The CW calibration tone power will be upgraded to monitor changes in the electronics gain and phase. The four S-band CBPMs are still to be investigated, the main problem associated with these cavities is a large cross coupling between the x and y ports. This combined with the large design dispersion in that degion makes the digital signal processing difficult, although various techniques exist to determine the cavity parameters and use these coupled signals for beam position determination.

Characterization of Slow Orbit Motion in the SPEAR3 (open access)

Characterization of Slow Orbit Motion in the SPEAR3

SPEAR3 is a third-generation synchrotron light source storage ring. The beam stability requirements are {approx}10% of the beam size, which is about 1 micron in the vertical plane. Hydrostatic level system (HLS) measurements show that the height of the SPEAR3 tunnel floor varies by tens of microns daily. We present analysis of the HLS data, including accounting for common-mode tidal motion. We discuss the results of experiments done to determine the primary driving source of ground motion. We painted the accelerator tunnel walls white; we temporarily installed Mylar over the asphalt in the center of the accelerator; and we put Mylar over a section of the tunnel walls.

Report on sodium compatibility of advanced structural materials. (open access)

Report on sodium compatibility of advanced structural materials.

This report provides an update on the evaluation of sodium compatibility of advanced structural materials. The report is a deliverable (level 3) in FY11 (M3A11AN04030403), under the Work Package A-11AN040304, 'Sodium Compatibility of Advanced Structural Materials' performed by Argonne National Laboratory (ANL), as part of Advanced Structural Materials Program for the Advanced Reactor Concepts. This work package supports the advanced structural materials development by providing corrosion and tensile data from the standpoint of sodium compatibility of advanced structural alloys. The scope of work involves exposure of advanced structural alloys such as G92, mod.9Cr-1Mo (G91) ferritic-martensitic steels and HT-UPS austenitic stainless steels to a flowing sodium environment with controlled impurity concentrations. The exposed specimens are analyzed for their corrosion performance, microstructural changes, and tensile behavior. Previous reports examined the thermodynamic and kinetic factors involved in the purity of liquid sodium coolant for sodium reactor applications as well as the design, fabrication, and construction of a forced convection sodium loop for sodium compatibility studies of advanced materials. This report presents the results on corrosion performance, microstructure, and tensile properties of advanced ferritic-martensitic and austenitic alloys exposed to liquid sodium at 550 C for up to 2700 h and at 650 C for …

Geochemical Implications of CO2 Leakage Associated with Geologic Storage: A Review (open access)

Geochemical Implications of CO2 Leakage Associated with Geologic Storage: A Review

Leakage from deep storage reservoirs is a major risk factor associated with geologic sequestration of carbon dioxide (CO2). Different scientific theories exist concerning the potential implications of such leakage for near-surface environments. The authors of this report reviewed the current literature on how CO2 leakage (from storage reservoirs) would likely impact the geochemistry of near surface environments such as potable water aquifers and the vadose zone. Experimental and modeling studies highlighted the potential for both beneficial (e.g., CO2 re sequestration or contaminant immobilization) and deleterious (e.g., contaminant mobilization) consequences of CO2 intrusion in these systems. Current knowledge gaps, including the role of CO2-induced changes in redox conditions, the influence of CO2 influx rate, gas composition, organic matter content and microorganisms are discussed in terms of their potential influence on pertinent geochemical processes and the potential for beneficial or deleterious outcomes. Geochemical modeling was used to systematically highlight why closing these knowledge gaps are pivotal. A framework for studying and assessing consequences associated with each factor is also presented in Section 5.6.
