Determining a Method to Pressure Test a Novel Type of Glass

Description: A novel type of glass made with a double ion exchange process is more reliable and fractures in a unique manner compared to glass currently available in the market. The novel glass is unique because it disintegrates into a powder instead of fracturing into shards and splinters, and it fails over a very narrow range of stresses. Potential applications for this glass include using it in removable valves because the powdered glass does not produce obstructions when it breaks, and in other applicat… more

Thermal History of the Felsite Unit, Geysers Geothermal Field, From Thermal Modeling of 40Ar/39Ar Incremental Heating Data

Description: An Ar-40/Ar-39 and U-Pb study was performed of the Geysers plutonic complex of the Geysers Geothermal Field in California. Sixty-nine ion microprobe spot analyses of zircons from four granite samples from the plutonic complex that underlies the Geysers geothermal field yielded Pb-207/Pb-206 vs. U-238/Pb-206 concordia ages ranging from 1.13 {+-} 0.04 Ma to 1.25 {+-} 0.04 Ma. The U-Pb ages coincide closely with Ar-40/Ar-39 age spectrum plateau and ''terminal'' ages from coexisting K-feldspars and… more

Physics design of the DARHT 2nd axis accelerator cell

Description: The next generation of radiographic machines based on induction accelerators require very high brightness electron beams to realize the desired x-ray spot size and intensity. This high brightness must be maintained throughout the beam transport, from source to x-ray converter target. The accelerator for the second-axis of the Dual Axis Radiographic Hydrodynamic Test (DARHT) facility is being designed to accelerate a 4-kA, 2-{micro}s pulse of electrons to 20 MeV. After acceleration, the 2-{micro… more

Mechanical engineering note - safety analysis of molten uranium/water interaction in the uranium foundry furnace

Description: This Engineering Note describes the development of the accident criteria used the basis for the design of the uranium foundry vacuum vessel. The results of this analysis provide input into other safety notes that investigate how well the uranium containment boundary will maintain its integrity during the design basis accident. The preventative measures that have been designed into the system to minimize the potential to produce a flammable gas mixture are described. The system response is desig… more

Baryogenesis and low energy CP violation

Description: CP violation is a crucial component in the creation of the matter - anti matter asymmetry of the universe. An important open question is whether the CP violating phenomena observeable in terrestrial experiments have any relation with those responsible for baryogenesis. We discuss two mechanisms of baryogenesis where this question can be meaningfully posed: ''electroweak baryogenesis'' and ''baryogenesis via leptogenesis''. We show how these scenarios can be constrained by existing and forthcomi… more

Portable Apparatus for the Measurement of Environmental Radon and Thoron

Description: The radometer is a portable instrument for the measurement of the concentration of atmospheric radon/thoron in a test area. A constant velocity pump pulls the air from the outside at a constant flow rate. If the air is too moist, some or all of the sample is passed through a desiccant filter prior to encountering an electrostatic filter. The electrostatic filter prevents any charged particles from entering the sampling chamber. Once the sample has entered the chamber, the progeny of the decay o… more

Unsteady Aerodynamics Experiment Phases II-IV Test Configurations and Available Data Campaigns

Description: The main objective of the Unsteady Aerodynamics Experiment is to provide information needed to quantify the full-scale three-dimensional aerodynamic behavior of horizontal axis wind turbines. To accomplish this, an experimental wind turbine configured to meet specific research objectives was assembled and operated at the National Renewable Energy Laboratory (NREL). The turbine was instrumented to characterize rotating blade aerodynamic performance, machine structural responses, and atmospheric … more

Large Delta I = 3/2 Contributions to epsilon'/epsilon in Supersymmetry

Description: We show that in supersymmetric extensions of the Standard Model gluino box diagrams can yield a large {Delta}I = 3/2 contribution to s {r_arrow} d{bar q}q FCNC processes, which may induce a sizable CP-violating contribution to the I = 2 isospin amplitude in K {r_arrow} {pi}{pi} decays. This contribution only requires moderate mass splitting between the right-handed squarks {tilde u}{sub R} and {tilde d}{sub R}, and persists for squark masses of order 1 TeV. Taking into account current bounds on… more

Multipole Spill-Down Effects in the SPEAR3 Dipole Magnets

Description: The main SPEAR3 dipole magnets are 1.45 m long with a pole contour designed to horizontally deflect and vertically focus the electron beam. At the nominal beam energy (3 GeV), the field and gradient along the magnet centerline are 1.3 T and 3.3 T/m (k = {minus}0.33 m{sup {minus}2}), respectively. Due to the straight core construction, the beam passes through each dipole with up to 16.6 mm trajectory offset relative to the centerline. This paper describes a method used to characterize the spilld… more

Effect of Insertion Devices in SPEAR3

Description: The SPEAR3 upgrade lattice will provide much reduced beam emittance to increase the brightness of synchrotron radiation beams from wigglers and undulators. Seven existing insertion devices will be used in the lattice. In this paper we review the wiggler parameters, outline the wiggler compensation scheme, and evaluate wiggler effect on the optics and dynamic aperture.

Signal trend identification with fuzzy methods.

Description: A fuzzy-logic-based methodology for on-line signal trend identification is introduced. Although signal trend identification is complicated by the presence of noise, fuzzy logic can help capture important features of on-line signals and classify incoming power plant signals into increasing, decreasing and steady-state trend categories. In order to verify the methodology, a code named PROTREN is developed and tested using plant data. The results indicate that the code is capable of detecting tran… more
