Data Archived for Events in the Caucasus for the CauSINCollaboration Project

The Causin project is a joint effort between the countries in the Caucasus region to develop a Probabilistic Seismic Hazard Analysis. To that end, we have compiled a database of all available network data in the region. The information contained in the database is from four countries: Armenia, Georgia, Azerbaijan, and Turkey and from the Incorporated Research Institutions for Seismology (IRIS). Table 1 lists the networks from which data were obtained. Figure 1 shows the locations of stations, and Figure 2 shows ray paths for event locations of the archived data. An ongoing effort in the region is the Caucasus Seismic Information Network (CauSIN) is an international scientific project enabling the countries and scientists of the region to: better understand the seismicity of the greater Caucasus; develop new monitoring networks to support the scientific understanding; provide access to seismic data from local networks in the participating countries; and develop a probabilistic seismic hazards assessment for the region enabling the governments in the region to better mitigate the damaging effects from large earthquakes. In parallel with this effort, training has been conducted on modern techniques for probabilistic hazards assessment. CauSIN is also an ongoing effort to promote cooperation in the geosciences between Georgia, Armenia, Azerbaijan, European Union and the United States. The DOE supports the American team from New England Research, Inc. (NER), Massachusetts Institute of Technology (MIT), Boston College, and Lawrence Livermore National Laboratory (LLNL)

Strengthening International Nuclear Forensic Capabilities Through Collaborative Science In Ukraine STRENGTHENING INTERNATIONAL NUCLEAR FORENSIC CAPABILITIES THROUGH COLLABORATIVE SCIENCE IN UKRAINE

ABSTRACT Globally, the production, transport and storage of nuclear materials have led to serious concerns over illegal trafficking of such materials. Ukraine stands at one of the geographical crossroads of such activities, and contains the largest uranium ore reserves in Europe. Moreover, Ukraine retains significant waste from Soviet-era uranium production and enrichment activities, as well as radioactive materials accumulated from the Chernobyl catastrophe. Lawrence Livermore National Laboratories (LLNL), with support through NA-242, has initiated multiple cooperative efforts within Ukraine, engaging some of the best Ukrainian scientists and institutions in nuclear forensic science. Nuclear forensics serves as a vehicle for scientific collaborations between the Ukrainian and United States governments, strengthening the response and core capabilities of Ukraine, who is also taking an active role as the regional leader in nuclear forensics, and additionally contributing to further engagements between respective governments. These collaborations are being supported through the Department of Energy, NA-242 GIPP (Global Initiatives for Proliferation Prevention) and CBM (Confidence Building Measures) programs, and serve to enhance nuclear forensics capabilities for Ukraine and neighboring countries, as well as in the United States. INTRODUCTION Ukraine stands at a geographical and geopolitical crossroads for illicit trafficking of nuclear materials, possessing the largest uranium ore reserves in Europe, as well as retaining significant waste from Soviet-era uranium production and enrichment activities, and radioactive materials accumulated from the Chernobyl catastrophe. Additionally, Ukraine supports a large uranium mining industry founded on a diverse set of geological settings and employing multiple uranium mining technologies, from open-pit to leach field mining. According to the illicit trafficking database maintained by the International Atomic Energy Agency (IAEA) [1,2], over the past two decades, more than one thousand cases have been confirmed by States Points of Contact, about 25% of which involved nuclear materials. Interdictions on nuclear materials, including samples consistent with origins in the former Soviet Unio

Demonstration of ignition radiation temperatures in indirect-drive inertial confinement fusion hohlraums

We demonstrate the hohlraum radiation temperature and symmetry required for ignition-scale inertial confinement fusion capsule implosions. Cryogenic gas-filled hohlraums with 2.2 mm-diameter capsules are heated with unprecedented laser energies of 1.2 MJ delivered by 192 ultraviolet laser beams on the National Ignition Facility. Laser backscatter measurements show that these hohlraums absorb 87% to 91% of the incident laser power resulting in peak radiation temperatures of TRAD=300  eV and a symmetric implosion to a 100  μm diameter hot core
