Electron-Impact Excitation of Multicharged Ions using MEIBEL

Electron-Impact Excitation of Multicharged Ions using Merged Electron-Ion Beams Energy Loss

Subject(s)
Content type(s)
Country
<<<!!!<<< 2019-12-04: The repository is no longer available >>>!!!>>> Presented here are excitation cross sections measured for a select number of transitions using the Merged Electron-Ion Beams Energy Loss (MEIBEL) experiment. This is a collaboration of JILA and the Multicharged Ion Research Facility (MIRF) at Oak Ridge National Laboratory (ORNL), where the apparatus is located. Since there exist a nearly infinite number of transitions in multicharged ions we have chosen a few that serve as benchmarks for theoretical efforts. Of particular interest are forbidden transitions which are often dominated by dielectronic resonances whose positions and magnitudes are difficult to predict theoretically.

The CBEO project uses a specific problem of water quality (hypoxia) as means of directly involving users and demonstrating the prototype’s utility. Data from the Test Bed are being brought into a CBEO Portal on a National Geoinformatics Grid developed by the NSF funded GEON. This is a cyberinfrastructure netwrok that allows users access to datasets as well as the tools with which to analyze the data. Currently, Test Bed data avaialble on the CBEO Portal includes Water Quality Model output and water quality monitorig data from the Chesapeake Bay Program's CIMS database. This data is also available as aggregated "data cubes". Avaialble tools include the Data Access System for Hydrology (DASH), Hydroseek and an online R-based interpolator.

Prompt Assessment of Global Earthquakes for Response

PAGER

Subject(s)
Content type(s)
Country
PAGER (Prompt Assessment of Global Earthquakes for Response) is an automated system that produces content concerning the impact of significant earthquakes around the world, informing emergency responders, government and aid agencies, and the media of the scope of the potential disaster. PAGER rapidly assesses earthquake impacts by comparing the population exposed to each level of shaking intensity with models of economic and fatality losses based on past earthquakes in each country or region of the world. Earthquake alerts – which were formerly sent based only on event magnitude and location, or population exposure to shaking – now will also be generated based on the estimated range of fatalities and economic losses. PAGER uses these earthquake parameters to calculate estimates of ground shaking by using the methodology and software developed for ShakeMaps. ShakeMap sites provide near-real-time maps of ground motion and shaking intensity following significant earthquakes. These maps are used by federal, state, and local organizations, both public and private, for post-earthquake response and recovery, public and scientific information, as well as for preparedness exercises and disaster planning.

Country
Strong-motion data of engineering and scientific importance from the United States and other seismically active countries are served through the Center for Engineering Strong Motion Data(CESMD). The CESMD now automatically posts strong-motion data from an increasing number of seismic stations in California within a few minutes following an earthquake as an InternetQuick Report(IQR). As appropriate,IQRs are updated by more comprehensive Internet Data Reports that include reviewed versions of the data and maps showing, for example, the finite fault rupture along with the distribution of recording stations. Automated processing of strong-motion data will be extended to post the strong-motion records of the regional seismic networks of the Advanced National Seismic System (ANSS) outside California.
