Fusion Energy Production by Deuterium Particle Injection Jamison Daniel 2012-09-28 | BEST VIEWED IN HD 720P.This visualization was created using simulations run on the supercomputers at the National Center of Computational Sciences and shows the expected operation of the ITER fusion reactor. This reactor is currently being built by a global coalition in Cadarache, France and is expected to begin the first experiments in 2020. To produce fusion reactions, the fuel must be heated to a temperature of over one hundred and fifty million degrees -- more than ten times the temperature of the sun's core. An initial plasma is formed and heated by driving an electric current through the fuel gas in the tokamak chamber. When the plasma reaches a sufficient density and temperature, the injectors are turned on. These very energetic beam ions are trapped by the magnetic field and circulate throughout the plasma, colliding with the plasma particles and transferring energy to them. As the temperature of the plasma rises, reactions between the plasma deuterium and tritium begin to occur.This research used resources of the Oak Ridge Leadership Computing Facility at the Oak Ridge National Laboratory, which is supported by the Office of Science of the U.S. Department of Energy under Contract No. DE-AC05-00OR22725.
Summit Supercomputer - Augmented Reality Machine Room Project - 2018 Jamison Daniel 2018-08-24 | In this project we investigate the current state of AR for use in the future workflows of profes-sional research environments. We aim to identify the challenges and considerations associatedwith augmenting the physical world with data. We also explore another presumed advantage ofAR: inspecting virtual 3D objects and data.For the purposes of this project, we obtained unique access to Summit, a new super computer atthe Department of Energy’s Oak Ridge National Lab (ORNL). We use 3D CAD files that com-pletely describe Summit’s cabinets along with the Summit machine room floor plan to develophologram versions of Summit. We then develop an application with two primary functions: anoverview mode that allows a user to inspect Summit as a whole, and a machine-room mode thatoverlays a hologram version of Summit onto the actual machine. We then add the capability forreal-time sensor data to augment the holograms. This application demonstrates a potential usecase for AR in a professional researching setting.Music: bensound.com
ITER Fusion Reactor Jamison Daniel 2012-10-08 | Within the tokamak, we see field coils, the vacuum vessel, blanket modules, divertor cassettes, and equipment for heating and diagnostics. Visible is one of the high-energy neutral beam injectors that heat and drive the plasma. The fusion fuel consists of deuterium and tritium, which are isotopes of ordinary hydrogen (shown in red and green in the visualization). To produce fusion reactions, the fuel must be heated to a temperature of about one hundred million degrees - about ten times the temperature of the core of the sun. At such temperatures, the electrons of atoms are stripped from the nuclei forming as a state of matter called plasma. One method of achieving these high temperatures is by injecting beams of high-energy neutral atoms into the tokamak. An initial plasma is formed and heated by driving an electric current through the fuel gas in the tokamak chamber. When the plasma reaches a sufficient density and temperature, the injectors are turned on. Because injected atoms are electrically neutral, they are unaffected by the magnetic field and can penetrate deep into the plasma before being ionized by collisions with plasma particles. These very energetic beam ions are trapped by the magnetic field and circulate throughout the plasma, colliding with the plasma particles and transferring energy to them. As the temperature of the plasma rises, due to the beam heating, fusion reactions between the plasma deuterium and tritium begin to occur.
NASA GEOS-5 : Evolving Atmospheric CO2 Concentration Jamison Daniel 2012-10-08 | BEST VIEWED IN HD 1080P.The following visualizations depict time evolving atmospheric CO2 concentration in the atmosphere as simulated using the NASA GEOS-5 (Global Earth Observing System) model running on Jaguar at ORNL. The higher CO2 concentrations in the northern hemisphere are due to anthropogenic emissions. This is a joint climate science ORNL-NASA project between David Erickson (ORNL) and Steven Pawson NASA / GMAO (Global Modeling and Assimilation Office)/ (GSFC) (Goddard Space Flight Center) and the visualization was completed by Jamison Daniel (ORNL).This research was also supported by the U.S. Department of Energy, Office of Science. Oak Ridge National Laboratory is managed by UT-Battelle, LLC, for the U.S. Department of Energy under Contract DE-AC05-00OR22725. This research used resources of the National Center for Computational Sciences at Oak Ridge National Laboratory (ORNL).

MicroCAT Scanner Jamison Daniel 2012-10-03 | BEST VIEWED IN HD 720P.Micro-CT captures images with spatial resolution in the micron domain and has major applications in small animal imaging, allowing in vivo tests and longitudinal analyses for disease studies and pharmaceutical development.
Himalayan Watershed Study - JAN and JUL Comparison Jamison Daniel 2012-10-03 | BEST VIEWED IN HD 1080P.During the winter months, a large amount of snow is deposited on the Himalayan slopes forming the largest water resources in northern India. The continuous melting of this snow feeds the north Indian rivers. During winter, heavy snowfall covers 80 to 90 percent of the Himalayan watershed. During the summer season, only 10 percent of the watershed is covered by snow. Current research is concerned with how climate change may affect heavily populated areas that are dependent on this perennial cycle.The LandScan Dataset comprises a worldwide population database compiled on a 30" X 30" latitude/longitude grid. LandScan has been developed as part of the Oak Ridge National Laboratory (ORNL) Global Population Project for estimating ambient populations at risk.The proper simulation of the distribution of water vapor in the climate system is essential to the accurate treatment of the hydrological cycle and the planetary radiation budget. These images show the simulated January and July instantaneous distribution of the total column water vapor from a high-resolution configuration of the CCSM Community Atmospheric Model.
Hydrologic Water Vapor Cycle Jamison Daniel 2012-10-03 | BEST VIEWED IN HD 1080P.The proper simulation of the distribution of water vapor in the climate system is essential to the accurate treatment of the hydrological cycle and the planetary radiation budget. These images show the simulated monthly-averaged distribution of the total column water vapor from a high-resolution configuration of the CCSM Community Atmospheric Model. Shown are months of December and January of the Pacific typhoon season. Each second of the animation shows a simulated 24 hour cycle.
Annual Fossil-Fuel CO2 Emissions Jamison Daniel 2012-10-03 | BEST VIEWED IN HD 1080P.The 2011 version of this database presents a time series recording 1° latitude by 1° longitude CO2 emissions in units of million metric tons of carbon per year from anthropogenic sources for 1751-2008. Detailed geographic information on CO2 emissions can be critical in understanding the pattern of the atmospheric and biospheric response to these emissions.Global, regional, and national annual estimates for 1751 through 2008 were published earlier (Boden et al. 2011). Those national, annual CO2 emission estimates were based on statistics about fossil-fuel burning, cement manufacturing and gas flaring in oil fields as well as energy production, consumption, and trade data, using the methods of Marland and Rotty (1984). The national annual estimates were combined with gridded 1° data on political units and 1984 human populations to create the new gridded CO2 emission time series. The same population distribution was used for each of the years as proxy for the emission distribution within each country. The implied assumption for that procedure was that per capita energy use and fuel mixes are uniform over a political unit.BEST VIEWED IN HD 1080PThe consequence of this first-order procedure is that the spatial changes observed over time are solely due to changes in national energy consumption and nation-based fuel mix. Increases in fossil-fuel CO2 emissions over time are apparent for most areas.Visualization Credit: Jamison Daniel, Thom Boden, and Bob Andres (Principal Investigator).
