Neutron Generators Developed at LBNL for Homeland Security andImaging Applications (open access)

Neutron Generators Developed at LBNL for Homeland Security andImaging Applications

The Plasma and Ion Source Technology Group at Lawrence Berkeley National Laboratory has developed various types of advanced D-D (neutron energy 2.5 MeV), D-T (14 MeV) and T-T (0-9 MeV) neutron generators for wide range of applications. These applications include medical (Boron Neutron Capture Therapy), homeland security (Prompt Gamma Activation Analysis, Fast Neutron Activation Analysis and Pulsed Fast Neutron Transmission Spectroscopy) and planetary exploration with a sub-surface material characterization on Mars. These neutron generators utilize RF induction discharge to ionize the deuterium/tritium gas. This discharge method provides high plasma density for high output current, high atomic species from molecular gases, long life operation and versatility for various discharge chamber geometries. Four main neutron generator developments are discussed here: high neutron output co-axial neutron generator for BNCT applications, point neutron generator for security applications, compact and sub-compact axial neutron generator for elemental analysis applications. Current status of the neutron generator development with experimental data will be presented.

U.S. Space Programs: Civilian, Military, and Commercial

The future of the U.S. human space flight program is dominating debate about NASA. Pursuant to the "Vision for Space Exploration" announced by President Bush in January 2004, the shuttle program is to be terminated in 2010. The Vision directs NASA to focus its activities on returning humans to the Moon by 2020 and eventually sending them to Mars. How to manage Department of Defense (DOD) space programs to avoid the cost growth and schedule delays that have characterized several recent projects is a key issue facing DOD. The appropriate role of the government in facilitating commercial space businesses is an ongoing debate.

U.S. Aerospace Industry: Progress in Implementing Aerospace Commission Recommendations, and Remaining Challenges (open access)

U.S. Aerospace Industry: Progress in Implementing Aerospace Commission Recommendations, and Remaining Challenges

A letter report issued by the Government Accountability Office with an abstract that begins "The U.S. aerospace industry's wide-ranging activities--including commercial aviation, national security, and space exploration--make it critical to the economic health and strategic strength of our nation. However, the industry faces challenges, such as a national air traffic management system that, in its present form, cannot handle expected increases in demand; an aging aerospace workforce; and an increasingly competitive global market. In response to these and other challenges, Congress established the Commission on the Future of the United States Aerospace Industry in 2001 to recommend potential actions by the federal government and others to support a robust aerospace industry in the 21st century. In 2002, the Commission made recommendations to address these challenges. This report discusses (1) the extent to which federal agencies have addressed selected Commission recommendations and (2) the challenges that remain in addressing the recommendations. Based on the opinions of former Commissioners and GAO research, GAO selected recommendations dealing with the national airspace system, space policy, government-wide management structure, international issues, the aerospace workforce, and research and development. This report is based on reviews of agency documents, literature, and interviews with aerospace experts and officials …

Next Generation Air Transportation System: Progress and Challenges Associated with the Transformation of the National Airspace System (open access)

Next Generation Air Transportation System: Progress and Challenges Associated with the Transformation of the National Airspace System

A letter report issued by the Government Accountability Office with an abstract that begins "In 2003, Congress created the Joint Planning and Development Office (JPDO) to plan for and coordinate, with federal and nonfederal stakeholders, a transformation from the current air traffic control system to the "next generation air transportation system" (NGATS) by 2025. Housed within the Federal Aviation Administration (FAA), JPDO has seven partner agencies: the Departments of Transportation, Commerce, Defense, and Homeland Security; FAA; the National Aeronautics and Space Administration (NASA); and the White House Office of Science and Technology Policy. FAA will have primary responsibility for implementing NGATS. This report addresses (1) the status of JPDO's efforts to plan for NGATS, (2) the key challenges facing JPDO, and (3) the key challenges facing FAA as it implements the transformation. To address these issues, GAO reviewed relevant documents, interviewed agency officials and stakeholders, and conducted an expert panel."
