Issues Involving The OSI Concept of Operation For Noble Gas Radionuclide Detection (open access)

Issues Involving The OSI Concept of Operation For Noble Gas Radionuclide Detection

The development of a technically sound protocol for detecting the subsurface release of noble gas radionuclides is critical to the successful operation of an on site inspection (OSI) under the CTBT and has broad ramifications for all aspects of the OSI regime including the setting of specifications for both sampling and analysis equipment used during an OSI. With NA-24 support, we are investigating a variety of issues and concerns that have significant bearing on policy development and technical guidance regarding the detection of noble gases and the creation of a technically justifiable OSI concept of operation. The work at LLNL focuses on optimizing the ability to capture radioactive noble gases subject to the constraints of possible OSI scenarios. This focus results from recognizing the difficulty of detecting gas releases in geologic environments - a lesson we learned previously from the LLNL Non-Proliferation Experiment (NPE). Evaluation of a number of important noble gas detection issues, potentially affecting OSI policy, has awaited the US re-engagement with the OSI technical community. Thus, there have been numerous issues to address during the past 18 months. Most of our evaluations of a sampling or transport issue necessarily involve computer simulations. This is partly due to …

Mapping Diffuse Seismicity Using Empirical Matched Field Processing Techniques (open access)

Mapping Diffuse Seismicity Using Empirical Matched Field Processing Techniques

The objective of this project is to detect and locate more microearthquakes using the empirical matched field processing (MFP) method than can be detected using only conventional earthquake detection techniques. We propose that empirical MFP can complement existing catalogs and techniques. We test our method on continuous seismic data collected at the Salton Sea Geothermal Field during November 2009 and January 2010. In the Southern California Earthquake Data Center (SCEDC) earthquake catalog, 619 events were identified in our study area during this time frame and our MFP technique identified 1094 events. Therefore, we believe that the empirical MFP method combined with conventional methods significantly improves the network detection ability in an efficient matter.

Medicare Home Oxygen: Refining Payment Methodology Has Potential to Lower Program and Beneficiary Spending (open access)

Medicare Home Oxygen: Refining Payment Methodology Has Potential to Lower Program and Beneficiary Spending

A letter report issued by the Government Accountability Office with an abstract that begins "Studies have found that Medicare payment rates for home oxygen exceeded other payers' rates. Congress has reduced home oxygen payment rates, capped rental payments after 36 months, and directed the Centers for Medicare & Medicaid Services (CMS), which administers Medicare, to use competitive bidding. GAO was asked to examine Medicare home oxygen payment policy. GAO describes how Medicare pays for home oxygen; the effect on Medicare's payments of using other methodologies and rates; and changes in beneficiary access. GAO reviewed federal laws and regulations, industry-reported costs, Medicare claims data and payment data from selected private insurers, the Department of Veterans Affairs (VA), and CMS's competitive bidding program."

Neglected Tropical Diseases: Background, Responses, and Issues for Congress

Over the past decade, global health has become a priority in U.S. foreign policy, more than tripling U.S. funding for such efforts. This report discusses neglected tropical diseases (NTDs), a group of 17 diseases that are found primarily among the poorest people in 149 countries and territories. NTDs are an important focus of U.S. global health assistance and may come under scrutiny as the 112th Congress debates spending levels for ongoing global health programs.

NSTX Plasma Response to Lithium Coated Divertor (open access)

NSTX Plasma Response to Lithium Coated Divertor

NSTX experiments have explored lithium evaporated on a graphite divertor and other plasma facing components in both L- and H- mode confinement regimes heated by high-power neutral beams. Improvements in plasma performance have followed these lithium depositions, including a reduction and eventual elimination of the HeGDC time between discharges, reduced edge neutral density, reduced plasma density, particularly in the edge and the SOL, increased pedestal electron and ion temperature, improved energy confinement and the suppression of ELMs in the H-mode. However, with improvements in confinement and suppression of ELMs, there was a significant secular increase in the effective ion charge Zeff and the radiated power in H-mode plasmas as a result of increases in the carbon and medium-Z metallic impurities. Lithium itself remained at a very low level in the plasma core, <0.1%. Initial results are reported from operation with a Liquid Lithium Divertor (LLD) recently installed.

Oral History Interview with Gilberto Hernandez, January 21, 2011 transcript

Oral History Interview with Gilberto Hernandez, January 21, 2011

The National Museum of the Pacific War presents an oral interview with Gilberto Hernandez. Hernandez was born in Corpus Christi, Texas 13 September 1925. He worked on farms at a very young age with his formal schooling ending after the third grade. After his induction into the US Army in 1943 he was sent to Camp Wolters, Texas for basic training. He was temporarily assigned to the 42nd Infantry Division and then shipped to Camp Brackenridge, Kentucky where he joined the 75th Infantry Division. After receiving advanced training the division boarded a ship for Liverpool, England. The unit was then stationed in La Havre, France until called upon to participate in the Battle of the Bulge. On 17 January 1945, Hernandez was severely wounded. Hernandez was taken to a field hospital and then to a general hospital in Paris. There his leg was partially amputated. He was then sent to Bushnell General Military Hospital in Brigham City, Utah. He comments on the crude construction of the prosthesis of which he was originally fitted. He was discharged July 1945.

Programmable Beam Spatial Shaping System for the National Ignition Facility (open access)

Programmable Beam Spatial Shaping System for the National Ignition Facility

A system of customized spatial light modulators has been installed onto the front end of the laser system at the National Ignition Facility (NIF). The devices are capable of shaping the beam profile at a low-fluence relay plane upstream of the amplifier chain. Their primary function is to introduce 'blocker' obscurations at programmed locations within the beam profile. These obscurations are positioned to shadow small, isolated flaws on downstream optical components that might otherwise limit the system operating energy. The modulators were designed to enable a drop-in retrofit of each of the 48 existing Pre Amplifier Modules (PAMs) without compromising their original performance specifications. This was accomplished by use of transmissive Optically Addressable Light Valves (OALV) based on a Bismuth Silicon Oxide photoconductive layer in series with a twisted nematic liquid crystal (LC) layer. These Programmable Spatial Shaper packages in combination with a flaw inspection system and optic registration strategy have provided a robust approach for extending the operational lifetime of high fluence laser optics on NIF.
