Correlated Forward-Backward Coulomb Dissociation and Luminosity Monitoring at Heavy Ion Colliders (open access)

Correlated Forward-Backward Coulomb Dissociation and Luminosity Monitoring at Heavy Ion Colliders

We present an expression for the rate of correlated Coulomb dissociation of both colliding nuclei at a heavy-ion collider. For the case of Au + Au at RHIC, the cross section for mutual correlated dissociation is about 3 barns. This process should be cleanly measured with very forward (zero degree) calorimeters proposed for RHIC. We also discuss prospects for luminosity monitoring using this process.

Ferrous scrap preheating system: Phase 3, Final report (open access)

Ferrous scrap preheating system: Phase 3, Final report

Utilizing electric arc smelters for making steel has allowed many smaller manufacturers to compete with large integrated mills. The electric arc furnace melts scrap to produce steel. The subject of this report is a Scrap Preheater that heats and cleans the arc furnace scrap using its own low cost natural gas energy supply. Scrap preheating can increase the capacity of a given arc furnace and reduce the operating costs. In addition it reduces the air emissions and allows utilization of lower cost scrap. The program was divided into three phases and was to culminate with an operating prototype at a demonstration host site steel mill. A host site agreement was executed and critical components were tested. The prototype scrap preheater was completely designed. It was sized to preheat 30 tons of scrap in a scrap bucket in 30 minutes. Energy is supplied by a rich fume reactor that completely oxidizes organics from the scrap and auxiliary natural gas. There were several delays and changes in the project that resulted in the host site requesting to withdraw from the program. Extensive efforts were made to secure a replacement host site. However, when another host could not be found, the project was …

Increased oil production and reserves from improved completion techniques in the Bluebell field, Uinta Basin, Utah. Tenth quarterly technical progress report, January 1, 1996--March 31, 1996. Revised (open access)

Increased oil production and reserves from improved completion techniques in the Bluebell field, Uinta Basin, Utah. Tenth quarterly technical progress report, January 1, 1996--March 31, 1996. Revised

The objective of this project is to increase oil production and reserves in the Uinta Basin by demonstrating improved completion techniques. Low productivity of Uinta Basin will is caused by gross production intervals of several thousand feet that contain perforated thief zones, water-bearing zones, and unperforated oil- bearing intervals. Geologic and engineering characterization and computer simulation of the Green River and Wasatch Formations in the Bluefell field will determine reservoir heterogeneities related to fractures and depositional trends. This will be followed by techniques based on the reservoir characterization. Transfer of the project results will be an ongoing component of the project. Data (net pay thickness, porosity, and water saturation) of more than 100 individuals beds in he lower Green River and Wasatch Formations were used to generate geostatistical realization (numerical- representation) of the reservoir properties. The data set was derived from the Michelle Ute and Malnar Pike demonstration wells and 22 other wells in a 20 (52 km{sup 2}) square-mile area. Beds were studied independently of each other. Principles of sequential Gaussian simulations were used to generate geostatistical realizations of the beds.

Micromachined chemical jet dispenser (open access)

Micromachined chemical jet dispenser

Goal is to develop a multi-channel micromachined chemical fluid jet dispenser that is applicable to prototype tests with biological samples that demonstrate its utility for molecular biology experiments. Objective is to demonstrate a new device capable of ultrasonically ejecting droplets from 10-200 {mu}m diameter capillaries that are arranged in an array that is linear or focused. The device is based on several common fabrication procedures used in MEMS (micro electro mechanical systems) technology: piezoelectric actuators, silicon, etc.

Quantum groups: Geometry and applications (open access)

Quantum groups: Geometry and applications

The main theme of this thesis is a study of the geometry of quantum groups and quantum spaces, with the hope that they will be useful for the construction of quantum field theory with quantum group symmetry. The main tool used is the Faddeev-Reshetikhin-Takhtajan description of quantum groups. A few content-rich examples of quantum complex spaces with quantum group symmetry are treated in details. In chapter 1, the author reviews some of the basic concepts and notions for Hopf algebras and other background materials. In chapter 2, he studies the vector fields of quantum groups. A compact realization of these vector fields as pseudodifferential operators acting on the linear quantum spaces is given. In chapter 3, he describes the quantum sphere as a complex quantum manifold by means of a quantum stereographic projection. A covariant calculus is introduced. An interesting property of this calculus is the existence of a one-form realization of the exterior differential operator. The concept of a braided comodule is introduced and a braided algebra of quantum spheres is constructed. In chapter 4, the author considers the more general higher dimensional quantum complex projective spaces and the quantum Grassman manifolds. Differential calculus, integration and braiding can be …

X-ray diagnostics of hohlraum plasma flow (open access)

X-ray diagnostics of hohlraum plasma flow

In this study we use spectroscopy and x-ray imaging to investigate the macroscopic plasma flow in mm-sized laser-produced hohlraum plasmas. By using multiple diagnostics to triangulate the emission on a single experiment, we can pinpoint the position of dopants placed inside the hohlraum. X-ray emission from the foil has been used in the past to measure electron temperature. Here we analyze the spatial movement of dopant plasmas for comparison to hydrodynamic calculations.
