Recent QCD results from CDF (open access)

Recent QCD results from CDF

In this paper we report recent QCD analysis with the new data taken from CDF detector. CDF recorded an integrated luminosity of 4.4 nb{sup {minus}1} during the 1988--1989 run at center of mass system (CMS) energy of 1.8 TeV. The major topics of this report are inclusive jet, dijet, trijet and direct photon analysis. These measurements are compared of QCD predictions. For the inclusive jet an dijet analysis, tests of quark compositeness are emphasized. 11 refs., 6 figs.

Dielectronic recombination into Rydberg levels of lithiumlike titanium (open access)

Dielectronic recombination into Rydberg levels of lithiumlike titanium

To characterize line formation near threshold for electron-impact excitation, dielectronic capture into high-n levels in lithiumlike Ti{sup 19+} ions has been studied with high-resolution x-ray spectroscopy on the Livermore electron beam ion trap. The process is shown to result in satellite lines which are virtually indistinguishable from their dipole-allowed heliumlike parent lines. High-n satellite lines are absent from dipole-forbidden heliumlike lines.

A global overview of risk management of the DOE complex (open access)

A global overview of risk management of the DOE complex

No endeavor is risk-fire and as we realize the inherent risks in society, our only viable solution is to manage the risk. Application of an integrated risk management program of a large technological system like the DOE complex is a difficult, task; but it is the only rational means to optimize the risk-benefit equation. An effective risk management culture-within the DOE complex will in the long run, ensure a consistent response to mitigate identified risks. An effective risk management program provides responsible administrative planning and logical application of the best technical analyses. It requires the involvement of all personnel. Our objective in this paper is to point out broad perspectives that raise concerns about future DOE ask management issues and to suggest some possible remedies.

The Deflection of Charged Particles in an Electric Dodecapole Field (open access)

The Deflection of Charged Particles in an Electric Dodecapole Field

The properties of an ion-optical device consisting of twelve long parallel rods placed equidistantly on a circle are briefly reviewed. The use of this device in its dodecapole configuration to deflect ions in a plane perpendicular to the axis of the dodecapole is discussed. Results of trajectory computations made with the SIMION ion-optics computer program demonstrate that the device works remarkably well in separating the constituents of a multiply-charged ion beam. The use of this device to merge an ion beam with an optical beam is proposed.

The HIPROTECT system (open access)

The HIPROTECT system

HIPROTECT (pronounced High-protect) is a system designed to protect national archaeological and natural treasures from destruction by vandals or looters. The system is being developed jointly by the Lawrence Livermore National Laboratory and the University of California at Riverside under the DOD Legacy Resource Management Program. Thousands of archaeological sites are located on military bases and national park lands. Treasure hunters or vandals are pillaging and destroying these sites at will, since the sites are generally located in remote areas, unattended and unprotected. The HIPROTECT system is designed to detect trespassers at the protected sites and to alert park officials or military officials of intrusions. An array of sensors is used to detect trespassers. The sensors are triggered when a person or vehicle approaches the site. Alarm messages are transmitted to alert park officials or law enforcement officials by way of a cellular telephone link. A video and audio system is included to assist the officials in verifying that an intrusion has occurred and to allow two-way communication with the intruders.

Methodologies for defining quality of life (open access)

Methodologies for defining quality of life

Quality of life as a concept has been used in many ways in the public policy arena. It can be used in summative evaluations to assess the impacts of policies or programs. Alternatively, it can be applied to formative evaluations to provide input to the formation of new policies. In short, it provides the context for the understanding needed to evaluate the results of choices that have been made in the public policy arena, or the potential of choices yet to be made. In either case, the public policy question revolves around the positive or negative impact the choice will have on quality of life, and the magnitude of that impact. This discussion will develop a conceptual framework that proposes that an assessment of quality of life is based on a comparison of expectations with experience. The framework defines four basic components from which these expectations arise: natural conditions, social conditions, the body, and the mind. Each one of these components is generally described, and associated with a general policy or rhetorical category which gives it its policy vocabulary--environmental quality, economic well-being, human health, and self-fulfillment.

Comparison of radiation safety and nuclear explosive safety disciplines (open access)

Comparison of radiation safety and nuclear explosive safety disciplines

In August 1945, U.S. Navy Captain William Parsons served as the weaponeer aboard the Enola Gay for the mission to Hiroshima (Shelton 1988). In view of the fact that four B-29s had crashed and burned on takeoff from Tinian the night before, Captain Parsons made the decision to arm the gun-type weapon after takeoff for safety reasons (15 kilotons of TNT equivalent). Although he had no control over the success of the takeoff, he could prevent the possibility of a nuclear detonation on Tinian by controlling what we now call the nuclear explosive. As head of the Ordnance Division at Los Alamos and a former gunnery officer, Captain Parsons clearly understood the role of safety in his work. The advent of the pre-assembled implosion weapon where the high explosive and nuclear materials are always in an intimate configuration meant that nuclear explosive safety became a reality at a certain point in development and production not just at the time of delivery by the military. This is the only industry where nuclear materials are intentionally put in contact with high explosives. The agency of the U.S. Government responsible for development and production of U.S. nuclear weapons is the Department of Energy …

Oxidation and volatilization of TZM alloy in air (open access)

Oxidation and volatilization of TZM alloy in air

The excellent high temperature strength and thermal conductivity of molybdenum-base alloys provide attractive features for components in advanced magnetic and inertial fusion devices. Refractory metal base alloys react readily with oxygen and other gases, and molybdenum alloys are susceptible to losses from highly volatile molybdenum trioxide (MoO{sub 3}) species. Transport of radioactivity by the volatilization, migration, and re-deposition of MoO{sub 3} during a potential accident involving a loss of vacuum or inert environment represents a safety issue. The authors have experimentally measured the oxidation, volatilization and re-deposition of molybdenum from TZM in flowing air between 400 and 800 C. Calculations using chemical thermodynamic data for vapor pressures over pure MoO{sub 3} and a vaporization mass transfer model correlate well with experimental data between 600 and 800 C. Partial saturation of MoO{sub 3} gas species account for influences of flow rate at 700 C. Some anomalies in oxidation rate below 650 C, suggesting that other phases, e.g., MoO{sub 2} or other non-stoichiometric oxides may influence oxidation and volatilization processes under some limited conditions.

Acoustic waves in random ensembles of magnetic fluxes (open access)

Acoustic waves in random ensembles of magnetic fluxes

To analyze the observational data and provide the appropriate diagnostic procedure for photospheric manifestation of solar oscillations it is necessary to take into account strong inhomogeneity of solar atmosphere with respect to distribution of magnetic fields. We study the collective phenomena in the propagation of acoustic waves and unsteady wave-packets through quite regions, sunspots and plages, including time-dependent response of these regions to solar oscillations, the energy transfer mechanisms, frequency shift effects and reradiation of the acoustic waves in higher layers of atmosphere. We show that the dynamics of differently magnetized regions, their dispersion properties, and their response to the propagation of acoustic waves are completely different. We describe the effects caused by the specific distribution and randomness of magnetic flux tubes, which can be observed and which can provide the tools for diagnostic goals.
