Download or read book Recent Advances in Nuclear Explosion Monitoring written by Martin B Kalinowski and published by Birkhäuser. This book was released on 2015-02-04 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a follow-up of PAGEOPH Topical Volume 167 (2010) and again reports on the latest advances in science and technology that have been achieved to monitor compliance with the Comprehensive Nuclear-Test-Ban Treaty (CTBT). This progress in the development and testing of new sensor technologies and analysis methodologies in all relevant scientific disciplines improves the detection, location and characterization of CTBT-relevant events. In particular the latter poses a challenge for smaller events, where natural or manmade but CTBT-irrelevant sources can generate false positive events. Being able to effectively identify these events while maintaining a minimum risk of missing a nuclear explosion is the overall challenge. The 29 papers in this volume can be structured into 16 waveform studies, eight contributions in the field of radionuclide monitoring and related atmospheric backtracking and five papers related to on-site inspection or overhead detection of relevant events, with many of these originally presented at a special session on “Research and Development in Nuclear Explosion Monitoring” at the most recent annual General Assemblies of the European Geosciences Union (EGU). The volume addresses the interests of scientists and practitioners whose work is related to the CTBT relevant applications and technologies in the fields of seismology, hydro-acoustics, infra-sound, meteorology and nuclear physics.

Available in PDF, EPUB and Kindle. Book excerpt: This topical volume focuses on the most recent advances that have been achieved in relevant fields of research of nuclear test ban monitoring, including seismology, infrasound- and hydro-acoustics, as well as nuclear physics and atmospheric backtracking. This research has been presented during the special sessions on "Research and Development in Nuclear Explosion Monitoring" convened during the 2007 and 2008 General Assemblies of the European Geosciences Union (EGU). The special sessions were introduced after the Preparatory Commission for the Comprehensive Nuclear Test-Ban Treaty Organization (CTBTO Prepcom) had convened a scientific symposium in 2006 on "CTBT: Synergies with Science 1996-2006 and beyond" marking the tenth anniversary of the United Nations General Assembly’s adoption of the CTBT Treaty. With regard to the seismo-acoustic fields several papers provide important updates on advances made in these fields since publication of ‘Monitoring the Comprehensive Nuclear-Test-Ban Treaty’ (see PAGEOPH topical volumes 158-159, 2001-2002). Moreover, this topical volume expands on these publications by including radionuclide and noble gas monitoring, as well as atmospheric transport modeling. In these two areas, significant progress has been made in recent years. Two papers studying the 2006 North Korean nuclear test elucidate how progress made in the relevant fields has allowed for a good understanding on the characteristics of this underground nuclear test.

This book was released on 2005-04-15 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, CISAC tackles the technical dimensions of a longstanding controversy: To what extent could existing and plausibly attainable measures for transparency and monitoring make possible the verification of all nuclear weaponsâ€"strategic and nonstrategic, deployed and nondeployedâ€"plus the nuclear-explosive components and materials that are their essential ingredients? The committee's assessment of the technical and organizational possibilities suggests a more optimistic conclusion than most of those concerned with these issues might have expected.

Available in PDF, EPUB and Kindle. Book excerpt: This document reviews the accessible literature, as it relates to nuclear explosion monitoring and the Comprehensive Nuclear-Test-Ban Treaty (CTBT, 1996), for four research areas: source physics (understanding signal generation), signal propagation (accounting for changes through physical media), sensors (recording the signals), and signal analysis (processing the signal). Over 40 trends are addressed, such as moving from 1D to 3D earth models, from pick-based seismic event processing to full waveform processing, and from separate treatment of mechanical waves in different media to combined analyses. Highlighted in the document for each trend are the value and bene t to the monitoring mission, key papers that advanced the science, and promising research and development for the future.
Download or read book Monitoring the Comprehensive Nuclear Test Ban Treaty Hydroacoustics written by Catherine de Groot-Hedlin and published by Springer. This book was released on 2012-12-06 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: In September 1996, the United Nations General Assembly adopted the Comprehensive Nuclear-Test-Ban Treaty (CTBT), prohibiting nuclear explosions worldwide, in all environments. The treaty calls for a global verification system, including a network of 321 monitoring stations distributed around the globe, a data communications network, an international data centre (IDC), and on-site inspections, to verify compliance. A global hydroacoustic monitoring system is being planned and implemented for verification of the CTBT. Much of the research conducted over the past several decades on acoustic surveillance of the oceans, formerly driven by the need to detect and track submarines, is now being applied to the development of effective monitoring methods to verify compliance with the CTBT. The aim of this volume on Hydroacoustic Monitoring of the CTBT is to summarize the research being conducted in this field and to provide basic references for future research. Much of the new research emphasizes major advances in understanding the coupling of ocean acoustic waves with elastic waves in the solid Earth. Topics covered include source excitation, detection and classification of events generating hydroacoustic signals, discrimination between underwater explosions and naturally occurring events, as well as topics in coupling of acoustic to seismic wavefields.
Download or read book Progress on Component Evaluation for Nuclear Explosion Monitoring written by and published by . This book was released on 2008 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ground-Based Nuclear Explosion Monitoring Research and Development (GNEM R & D) program at Sandia National Laboratories (SNL) is regarded as the primary center for unbiased expertise in testing and evaluation of geophysical sensors and instrumentation for nuclear explosion monitoring. We had four main areas of interest to make progress on this year; this report will cover the advances made in these areas. First is the continued development and research of the three-component coherence technique of Sleeman et al. (2006). We have reverted back to synthetic testing to develop a firm understanding of the arithmetic limitations in processing to recover small value estimates of noise relative to large input signals. We explored the effects of digital quantization of the analog signal, as well as the limitations of the technique in the presence of high signal-to-noise input signals. The second area of interest is the upgrade of our suite of software used to analyze sensors and digitizer data (e.g., to calculate noise floor, time-tag accuracy). This past year has allowed us time to develop the new data model and relevant meta-architecture, proto-type existing algorithms in MATLAB with validation against existing tool sets, and develop sets of reusable modules (e.g., waveform editing tools and test description). Our third area of concentration over the past year focused on testing new components for both Provisional Technical Secretariat and the Air Force Technical Applications Center (AFTAC). Characterization reports were produced for two infrasound sensors, Chaparral Physics model 2.5 low-gain and the Inter-Mountain Labs model SS avalanche sensor as well as one data logger, Geotech Smart24. For the infrasound sensors tested, the test results allow us to conclude that both sensors had sufficiently quiet noise floor to be at or below the Acoustic low-noise model from 0.1 to 7 Hz, which make these sensors suitable to explosion monitoring.

Available in PDF, EPUB and Kindle. Book excerpt: The Research and Development Support Services (RDSS) project of the Space and Missile Defense Command (SMDC) provides a range of resources and services for use in nuclear explosion monitoring R&D. This presentation focuses on some recent enhancements to the infrasound, seismic, and hydroacoustic resources, which can be accessed from the RDSS website at http://www.rdss.info. In particular, ongoing developments and improvements are related to (1) the nuclear explosion database (NEDB) and (2) infrasound signals and associated source information. The RDSS project has traditionally maintained an archive of information on source parameter data and waveforms from worldwide nuclear explosions. A major revision and update of the NEDB includes newly published or revised source information about historical explosions, access to additional or corrected waveform data for some explosions, and new data from more recent nuclear tests (viz., North Korea). New web tools for accessing the NEDB archive include GoogleMap visualization of alternative event locations, displays of recording station information (e.g., data availability and station parameters), seismic travel time residual displays, and new waveform display and retrieval options, which include options for simple prefiltering and signal rescaling during data review prior to download. Identification of infrasound events for the RDSS infrasound database has continued. The effort is based primarily on seismic-event bulletins, volcanic activity reports, meteor observations, announcements on rocket launches and information appearing in the news media. The search for infrasound signals associated with events in these reports and bulletins is utilizing the automatic detection lists of International Monitoring System (IMS) stations augmented with the processing of waveform data from the SMDC waveform archive.
Download or read book The Comprehensive Nuclear Test Ban Treaty written by National Research Council and published by National Academies Press. This book was released on 2012-04-29 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report reviews and updates the 2002 National Research Council report, Technical Issues Related to the Comprehensive Nuclear Test Ban Treaty (CTBT). This report also assesses various topics, including: the plans to maintain the safety and reliability of the U.S. nuclear stockpile without nuclear-explosion testing; the U.S. capability to detect, locate, and identify nuclear explosions; commitments necessary to sustain the stockpile and the U.S. and international monitoring systems; and potential technical advances countries could achieve through evasive testing and unconstrained testing. Sustaining these technical capabilities will require action by the National Nuclear Security Administration, with the support of others, on a strong scientific and engineering base maintained through a continuing dynamic of experiments linked with analysis, a vigorous surveillance program, adequate ratio of performance margins to uncertainties. This report also emphasizes the use of modernized production facilities and a competent and capable workforce with a broad base of nuclear security expertise.
