ERA-40 SST and Sea Ice Concentration Data

Description: The lower boundary condition of sea surface temperature (SST) and sea-ice concentration (sic) is a critical forcing of the lower frequencies in multi-decadal global atmospheric reanalyses such as ERA-40. Partly in response to the ERA-40 project, new SST/sic data sets have been developed that are considerably improved over those available to the first-generation reanalyses. This paper documents the input SST/sic data sets and the processing that created the daily SST/sic specification for the ER… more

Strong Field Physics With Mid Infrared Lasers.

Description: Mid-infrared gas laser technology promises to become a unique tool for research in strong-field relativistic physics. The degree to which physics is relativistic is determined by a ponderomotive potential. At a given intensity, a 10 {micro}m wavelength CO{sub 2} laser reaches a 100 times higher ponderomotive potential than the 1 {micro}m wavelength solid state lasers. Thus, we can expect a proportional increase in the throughput of such processes as laser acceleration, x-ray production, etc. Th… more

High Resolution Imaging with AEOS

Description: The U. S. Air Force Advanced Electro-Optical System (AEOS) which includes a 941 actuator adaptive optics system on a 3.7m telescope has recently been made available for astronomical programs. Operating at a wavelength of 750 nm, the diffraction-limited angular resolution of the system is 0.04 inches; currently, the magnitude limit is V {approx} 7 mag. At the distances of nearby open clusters, diffraction-limited images should resolve companions with separations as small as 4-6 AU--comparable to… more

Marangoni Convection Induced Ripple on Grazing Incidence Liquid Metal Mirror (GILMM) Used for Laser Inertial Fusion Energy

Description: A spatial variation of temperature in the sodium film on the surface of the grazing incidence liquid metal mirror (GILMM) will give rise to convection due to the temperature dependent variation in surface tension. This is called thermal capillary convection or the Marangoni effect and causes the surface to have ripples or waves. This note estimates the magnitude of this effect and finds, with care, design parameters can be chosen to make the resulting ripples sufficiently small so that a laser … more

Detecting Translation Errors in CAD Surfaces and Preparing Geometries for Mesh Generation

Description: The authors have developed tools for the efficient preparation of CAD geometries for mesh generation. Geometries are read from IGES files and then maintained in a boundary-representation consisting of a patchwork of trimmed and untrimmed surfaces. Gross errors in the geometry can be identified and removed automatically while a user interface is provided for manipulating the geometry (such as correcting invalid trimming curves or removing unwanted details). Modifying the geometry by adding or de… more

Switchyard Enclosure Seismic Criteria Calculations

Description: Finite Element Analysis (FEA) was conducted on these four Beam Enclosure Assembly drawings: (1) AAA97-108954 (Quad); (2) AAA97-108981 (Quad Intermediate); (3) AAA98-101193 (Bundle); and (4) AAA97-108982 (Double Quad). Each drawing chosen represents one of the four enclosure types: Quad, Quad Intermediate, Bundle, and Double Quad. They were chosen because they have the longest length between supports for their type and are therefore the worse case condition from the standpoint of seismic induced… more

Wind Energy Resource Atlas of Mongolia

Description: The United States Department of Energy (DOE) and the United States Agency for International Development (USAID) sponsored a project to help accelerate the large-scale use of wind energy technologies in Mongolia through the development of a wind energy resource atlas of Mongolia. DOE's National Renewable Energy Laboratory (NREL) administered and conducted this project in collaboration with USAID and Mongolia. The Mongolian organizations participating in this project were the Scientific, Producti… more

The CDF Run 2 Offline Computer Farms

Description: Run 2 at Fermilab began in March 2001. CDF will collect data at a maximum rate of 20 MByte/sec during the run. The offline reconstruction of this data must keep up with the data taking rate. This reconstruction occurs on a large PC farm, which must have the capacity for quasi-real time data reconstruction, for reprocessing of some data and for generation and processing of Monte Carlo samples. In this paper they give the design requirements for the farm, describe the hardware and software design… more

The CDF data acquisition system for Tevatron Run II

Description: The CDF experiment at the Fermilab Tevatron has been significantly upgraded for the collider Run II, which started in March 2001 and is scheduled to last until 2006. Instantaneous luminosities of 10{sup 32} cm{sup -2} s{sup -1} and above are expected. A data acquisition system capable of efficiently recording the data has been one of the most critical elements of the upgrade. Key figures are the ability to deal with the short bunch spacing of 132 ns, event sizes of the order of 250 kB, and perm… more
