Mass and lifetime measurements with exclusive B reconstruction at CDF (open access)

Mass and lifetime measurements with exclusive B reconstruction at CDF

Lifetimes and masses of B mesons have been measured in exclusively reconstructed decays including J/{psi} {yields} {mu}{sup +} decays. In 19.3 pb{sup {minus}1} of {bar p}p collisions at {radical}s = 1.8 TeV taken in 19920--93 at the Fermilab Tevatron collider, approximately 300 B mesons have been fully reconstructed. The measurements require precise determination of the helical track parameters of charged particle tracks. We find M(B{sub S}{sup O}) = 5367.7 {plus_minus} 2.4 {plus_minus} 4.8 MeV/c{sup 2}, {tau}(B{sup +}) = 1.61 {plus_minus} 0.16 {plus_minus} 0.05 ps, and {tau}(B{sup O}) = 1.57 {plus_minus} 0.18 {plus_minus} 0.08 ps.

Inspection of the cost reduction incentive program at the Department of Energy`s Idaho Operations Office (open access)

Inspection of the cost reduction incentive program at the Department of Energy`s Idaho Operations Office

The purpose of this inspection was to review the economy and efficiency of Idaho`s Fiscal Year 1992 Cost Reduction Incentive Program, as well as to provide information to Departmental officials regarding any difficulties in administering these types of programs. The report is of the findings and recommendations. According to Idaho officials, their Cost Reduction Incentive Program was designed to motivate and provide incentives to management and operating contractors which would result in cost savings to the Department while increasing the efficiency and effectiveness of the contractors` operations. Idaho officials reported that over $22.5 million in costs were saved as a result of the Fiscal Year 1992 Cost Reduction Incentive Program. It was found that: (1) Idaho officials acknowledged that they did not attempt a full accounting records validation of the contractor`s submitted cost savings; (2) cost reduction incentive programs may result in conflicts of interest--contractors may defer work in order to receive an incentive fee; (3) the Department lacks written Department-wide policies and procedures--senior Procurement officials stated that the 1985 memorandum from the then-Assistant Secretary for Management and Administration was not the current policy of the Department; and (4) the Department already has the management and operating contract award fee …

Demonstration testing and evaluation of in situ soil heating. Treatability study work plan, Revision 1 (open access)

Demonstration testing and evaluation of in situ soil heating. Treatability study work plan, Revision 1

A Treatability Study planned for the demonstration of the in situ electromagnetic (EM) heating process to remove organic solvents is described in this Work Plan. The treatability study will be conducted by heating subsurface vadose-zone soils in an organic plume adjacent to the Classified Burial Ground K-1070-D located at K-25 Site, Oak Ridge. The test is scheduled to start during the fourth quarter of FY94 and will be completed during the first quarter of FY95. The EM heating process for soil decontamination is based on volumetric heating technologies developed during the `70s for the recovery of fuels from shale and tar sands by IIT Research Institute (IITRI) under a co-operative program with the US Department of Energy (DOE). Additional modifications of the technology developed during the mid `80s are currently used for the production of heavy oil and waste treatment. Over the last nine years, a number of Government agencies (EPA, Army, AF, and DOE) and industries sponsored further development and testing of the in situ heating and soil decontamination process for the remediation of soils containing hazardous organic contaminants. In this process the soil is heated in situ using electrical energy. The contaminants are removed from the soil due …

Field studies of beach cones as coastal erosion control/reversal devices for areas with significant oil and gas activities. Annual report, February 24, 1993--February 23, 1994 (open access)

Field studies of beach cones as coastal erosion control/reversal devices for areas with significant oil and gas activities. Annual report, February 24, 1993--February 23, 1994

The primary objective of this project was to evaluate the utility of a device called the ``beach cone`` in combating coastal erosion. Seven initial sites were selected for testing beach cones in a variety of geometric configurations, and six sites were actually used. Six hundred beach cones were installed at the six sites in late July and early August, 1992. An additional 109 cones were installed at an eighth site in December of 1992. Findings indicate that beach cones accreted significant amounts of materials along the beach of a barrier island. At the eighth installation the amount of accreted material was measured by surveys to be 2200 cubic meters (2900 cubic yards) in February of 1993, when the cones were found to have been completely covered by the material. The average increase in elevation was about 7 inches (0. 18 in) with a maximum buildup of 3 ft. (I in). At other test sites, accretion rates have been less dramatic but importantly, no significant additional erosion has occurred, which is a positive result. The cost of sediment accretion using beach cones was found to be about $13.72 per cubic yard of sand or approximately $500,000 per mile of beach, which …

Slow beam raster system at CEBAF (open access)

Slow beam raster system at CEBAF

A bedstead air-core raster magnet is being installed now, it will be used at CEBAF to scan the beam on the Hall C polarized target and the beam dump with fixed frequency 60 Hz in horizontal, 103.4 Hz in vertical. The x and y raster magnets are driven by Variac transformer and SUMIT-OMO inverter respectively. Both of them provide an approximate sine current waveform with peak current 20 A, corresponding to a maximum deflection angle 1 mr.
