Finite element stress analysis of D0 test beam transporter mainframe assembly

Description: The D0 test beam transporter mainframe assembly is a structural frame lying in a horizontal plane and designed to support and orient the D0 test liquid argon calorimeter properly in the test beam. Azimuthal adjustment is provided by a turntable with a mean radius of 64 inches, supported on a pressurized oil bearing. Angular positioning is achieved by an hydraulic actuator attached to the turntable which places force against an arm on the calorimeter vessel, causing it to rotate. Vertical positi… more

Automated microscopy methods for measuring pyritic sulfur content of coal and determining degree of liberation of pyrite in coal: Final report

Description: The objective of this project is to develop an automated procedure, to be implemented in an IBAS image analyzer, to determine size, shape and degree of liberation of pyrite particles in a coal matrix. This procedure is to work in real time conditions and with minimal intervention from the operator. Our approach is to create from the original microscopic image a three level image with the following components: epoxy, coal macerals and pyrite to simplify the calculations. Enhancing the original i… more

Multidimensional modeling of convective heat transfer with application to IC (internal combustion) engines

Description: The objective of this project is to develop a more comprehensive understanding of the convective heat transfer process in complex, unsteady turbulent reacting flows, typical of those which occur in internal combustion engines. The specific area of research will be the representation of heat transfer in detailed multi-dimensional Navier-Stokes models, and modeling of turbulent transport mechanisms. The detailed tasks will include a review of relevant prior work. Based on this review, and origina… more

Assessment of the proposed decontamination and waste treatment facility at LLNL

Description: To provide a centralized decontamination and waste treatment facility (DWTF) at LLNL, the construction of a new installation has been planned. Objectives for this new facility were to replace obsolete, structurally and environmentally sub-marginal liquid and solid waste process facilities and decontamination facility and to bring these facilities into compliance with existing federal, state and local regulations as well as DOE orders. In a previous study, SAIC conducted a preliminary review and… more

The potential for reducing the cost of a heavy ion accelerator for ICF: Final report

Description: This study was initiated to identify the high leverage areas for reducing the cost of a 10 MJ heavy ion beam driver for a high gain target development facility. Our efforts to innovate to reach affordable cost have been mostly successful, in that it looks like the $500 M range may indeed be possible. We conclude that heavy ion beams do have substantial promise for an inertial fusion driver. However, the pace of R and D would have to be substantially increased to realize this promise on a timesc… more

A technique for production glass macro-shells for ICF targets. Final report, 1 November 1986--31 October 1987

Description: A study of bubble formation, movement and distortion in viscous glass is described. A glass rod containing an irregularly shaped hole is heated to a temperature at where the glass viscosity is low enough to let the hole form a spherical bubble. Spheration occurs as the bubble moves upward in the glass rod. At the proper time, the rising bubble is decelerated and brought to a stop by increasing the glass viscosity by slowly reducing the temperature. The entrapped bubble is then cut from the glas… more
