3D simulations of an electrostatic quadrupole injector

Description: Analysis of the dynamics of a space charge dominated beam in a lattice of electrostatic focusing structures requires a full three-dimensional conic that includes self-consistent space charge fields and the fields from the complex conductor shapes. The existing WARP3d code, a particle simulation code which has been developed for heavy-ion fusion (HIF) applications contains machinery for handling particles in three-dimensional fields. A successive overrelaxation field solver with subgrid-scale pl… more

Acid-permanganate oxidation of potassium tetraphenylboron

Description: Scoping experiments have been performed which show that potassium tetraphenylboron (KTPB) is rapidly oxidized by permanganate in acidic solutions at room temperature. The main Products are CO[sub 2], highly oxidized organic compounds related to tartaric and tartronic acids, boric acid, and potassium phosphate (when phosphoric acid is used as the source of acid). One liter of 0.6M NaMnO[sub 4]/2.5M H[sub 3]PO[sub 4] solution will destroy up to 8 grams of KTPB. The residual benzene concentration … more

Advanced direct liquefaction concepts for PETC generic units. Quarterly technical progress report, October 1992--December 1992

Description: The reactivity of the THF insoluble fraction of the ashy resid component of Wilsonville recycle oil (WRO) during liquefaction of Black Thunder coal in tetralin was determined at 415{degrees}C and 60 minutes. The liquefaction runs were made by combining this material with Black Thunder coal at the same ratio used in the WRO coal runs. THF conversion and product distribution from liquefaction in tetralin in the presence of the THF insoluble fraction of the ashy resid were similar to results from … more

Advances in the identification of electrochemical transfer function models using Prony analysis

Description: This paper further advances the usefulness and understanding of Prony analysis as a tool for identification of power system electromechanical oscillation models. These linear models are developed by analyzing power system ring-down data. The presented results allow more generality in the assumed model formulation. In addition, a comparison is made between Prony analysis and autoregressive moving-average (KARMA) modeling, which has also been proposed for analysis of system oscillations. Under th… more

An aerial radiological survey of the Superconducting Super Collider Laboratory and surrounding area, Waxahachie, Texas. Date of survey: July--August 1991

Description: An aerial radiological survey was conducted over the Superconducting Super Collider Laboratory (SSCL) site from July 22 through August 20,1991. Parallel lines were flown at intervals of 305 meters over a 1,036-square-kilometer (400-square-mile) area surrounding Waxahachie, Texas. The 70,000 terrestrial gamma energy spectra obtained were reduced to an exposure rate contour map overlaid on a United States Geological Survey (USGS) map of the area. The mean terrestrial exposure rate measured was 5.… more

The ALEXIS data processing package: An update

Description: The ALEXIS experiment (Array of Low Energy X-ray Imaging Sensors), is a mini-satellite containing six wide angle EUV/ultrasoft x-ray telescopes. Its purpose is to map out the sky in three narrow (5%) bandpasses around 66, 71, and 93 eV. The 66 and 71 eV bandpasses are centered on intense Fe emission lines which are characteristic of million-degree plasmas such as the one thought to produce the soft x-ray background. The 93 eV bandpass is not near any strong emission lines and is more sensitive … more

Alloy development of FeAl aluminide alloys for structural use in corrosive environments

Description: Objectives include adequate ductilities ({ge}10%) at ambient temperature, high-temperature strength better than stainless steels (types 304 and 316), and fabricability and weldability by conventional techniques (gas tungsten arc). The alloys should be capable of being corrosion resistant in molten nitrate salts with rates lower than other iron-base structural alloys and coating materials (such as Fe-Cr-Al alloys). Such corrosion rates should be less than 0.3 mm per year. The FeAl aluminide cont… more

Analysis of an MCG/fuse/PFS experiment

Description: The Los Alamos PROCYON high-explosive pulsed power (HEPP) implosion system is intended to produce 1 MJ of soft X-radiation for fusion and material studies. The system uses the MK-IX magnetic flux compression generator to drive a ``slow`` opening switch which, upon operation, connects the output of the MK-IX generator to a plasma flow switch, which, in turn, delivers current to a rapidly imploding load. The closing switch isolates the plasma flow switch (PFS) and load from any precursor current … more

Analysis of historical residential air-conditioning equipment sizing using monitored data

Description: Monitored data were analyzed to determine whether residential air conditioners in the Pacific Northwest historically have been sized properly to meet or slightly exceed actual cooling requirements. Oversizing air-conditioning equipment results in a loss of efficiency because of increased cycling and also lowers humidity control. On the other hand, the penalty of undersizing air-conditioning equipment may be some loss of comfort during extremely hot weather. The monitored data consist of hourly … more

Analysis of SPRIHTE LOPA flow excursion tests

Description: The SPRIHTE FLOPA flow excursion tests, the results of which are presented here, have been modeled using FLOPA, the assembly thermal-hydraulics limits analysis code for the LOPA. FLOPA calculations show T{sub wall} = T{sub sat} is a reliable precursor to the onset of thermal excursion at prototypic flow rates during the ECS addition phase of the LOPA. A FLOPA model was created based on nominal dimensions for the SPRIHTE rig and an assumption that the rig`s cylinders were concentrically located.… more
