Ampacity test of 28 AWG ribbon cables

Description: This report contains the results of testing ribbon cables in order to determine the amount of current they can carry. In some experiments ribbon cables are used to power circuit boards and carry several amperes of current. These tests were required to establish safe operating current limits for electrical safety reviews. The basic principle behind these tests was to increase the amount of current passed through the ribbon cables until the insulation melted and the cable clearly became a fire ha… more

Analysis and Correction of the Closed Orbit Distortion for RHIC

Description: This is a review of the RHIC sensitivity to closed orbit distortion and of the errors that are the cause. There are four sections. In the first we review the analytical calculation of the expectation values of the distortion and we compare the results with those obtained with numerical calculation. The expected uncorrected closed orbit distortion is so large to cause some concern for day-one operation of RHIC which is discussed in the second section where methods are proposed for investigation.… more

Approach to developing a ground-motion design basis for facilities important to safety at Yucca Mountain

Description: The Department of Energy has proposed a methodology for developing a ground-motion design basis for prospective facilities at Yucca Mountain that are important to safety. The methodology utilizes a quasi-deterministic construct that is designed to provide a conservative, robust, and reproducible estimate of ground motion that has a one-in-ten chance of occurring during the preclosure period. This estimate is intended to define a ground-motion level for which the seismic design would ensure mini… more

Aspects of meson spectroscopy with N N annihilation

Description: We focus on the potentialities of nucleon-antinucleon ({bar N}N) annihilation as a means of producing new mesonic states. The case for the existence of quasinuclear {bar N}N bound states is discussed in detail. Strong evidence for a 2{sup ++}(0{sup +}) state of this type has been obtained at LEAR in annihilation from the p-wave (L = 1) {bar N}N system, in support of earlier sightings of this object in L = 0 annihilation at Brookhaven. In the next generation of LEAR experiments, the emphasis shi… more

Beam impedance of a split cylinder

Description: A common geometry for position electrodes at moderately low frequencies is the capacitive pickup consisting of a diagonally- divided cylinder that encloses the beam trajectory. For the simplified system here, a relatively direct approach will given the longitudinal and transverse beam impedances (Z{parallel}and Z{perpendicular}) at low frequencies. This paper discusses the determination of this impedance.

Benchmarking of energy time series

Description: Benchmarking consists of the adjustment of time series data from one source in order to achieve agreement with similar data from a second source. The data from the latter source are referred to as the benchmark(s), and often differ in that they are observed at a lower frequency, represent a higher level of temporal aggregation, and/or are considered to be of greater accuracy. This report provides an extensive survey of benchmarking procedures which have appeared in the statistical literature, a… more

Beneficial effects of groundwater entry into liquid-dominated geothermal systems

Description: In all active liquid-dominated geothermal systems there is continuous circulation of mass and transfer of heat, otherwise they would slowly cool and fade away. In the natural state these systems are in dynamic equilibrium with the surrounding colder groundwater aquifers. The ascending geothermal fluids cool conductively, boil, or mix with groundwaters, and ultimately may discharge at the surface as fumaroles or hot springs. With the start of fluid production and the lowering of reservoir pressu… more

Cascade Collapse in Copper and Nickel

Description: In-situ TEM studies of the development of the damage structure produced by heavy ion irradiations have been performed in copper and nickel to investigate the possibility that melting occurs in local regions within displacement cascades. These experiments reveal that as the ion dose increases additional loops form from isolated displacement cascades, but more surprisingly some fo the pre-existing loops are annihilated, change position, size and/or Burgers vector. It was also found that the proba… more

Chern-Simons and anyonic superconductivity

Description: Anyons are particles with fractional statistics. They can exist as point particles in a 2+1 dimension, or as quasiparticles in quasiplanar condensed matter systems in the real world. Anyonic particles can be modeled by ordinary bosons or fermions coupled to a statistical'' Chern-Simons abelian gauge field. For certain values of the statistics phase, a plasma of anyons in the Chern-Simons description is a superconductor. Anyonic superconductivity may represent an idealized limit of a new type of… more
