Assessment of resonance ionization mass spectrometry for analytical chemistry and spectroscopy

Description: Resonance ionization mass spectrometry (RIMS) is a natural outgrowth of RIS. The result of an RIS process is an ion pair. The electron can be used to detect the process, and single atom detection has been demonstrated by this method. The cation resulting from the RIS process actually carries more easily accessible and useful information (i.e. the mass of the ion). RIMS is useful in mass analysis. The development of RIMS has proceeded along several different directions, using CW or pulsed lasers… more

Comparison of the initial ETA gas propagation experiments with theoretical models

Description: This report contains a description of the initial ETA propagation experiments in air at a beam current of 4.5 kA. The beam was observed to propagate at the pressures anticipated on the basis of previous theory and experiment. A comparison of measured net current waveforms with predictions of the PHOENIX code showed good agreement over the pressure range 0.1 to 200 torr. However, the beam was observed to expand with Z at a faster rate than theory predicts. Excessive transverse beam modulation at… more

Estimating the Cerenkov neutron sensitivity of Suprasil (SiO/sub 2/) and Lucite (C/sub 5/H/sub 8/O/sub 2/)

Description: Fast neutrons hitting a sample of suprasil will produce light. This light is Cerenkov light produced by high energy (> .2 MeV) electrons traversing the transparent medium. Neutrons produce these electrons in a two step process. First, the neutrons inelastically scatter with either the silicon (Si) or the oxygen (O) atoms producing inelastic gamma rays. Some of these gammas, in turn, will also react producing, primarily, Compton electrons with some pair production electrons possible. The majorit… more

Facile reaction/extraction of coal with supercritical fluids. Quarterly technical progress report, January 1-March 31, 1984

Description: Arylmethyl phenyl ethers undergo competing reactions when treated with Lewis acids in benzene solvent. Apparently, benzene is insufficiently reactive to compete with intramolecular (intrapolymer) nucleophiles and, consequently, no increase in solubility accompanies the cleavages of ether links upon addition of benzene. When better nucleophiles, naphthalene and phenanthene, are provided, carbonium ions generated from ether cleavages are capped and the product is lower in molecular weight and mor… more

Funneling: an initial beam dynamics study

Description: Funneling two H/sup -/ beams into a single beam of twice the current has been examined as a means of doubling beam current without significantly increasing transverse emittance. Using the PARMILA particle-following code, two 100-mA RFQ output beams at 2 MeV were injected into idealized transport lines for merging two beams into one. Two approaches were studied: (1) the minimum-element method, in which a minimum number of discrete elements such as quadrupole triplets, buncher cavities, and bendi… more

Fusion breeder

Description: The fusion breeder is a fusion reactor designed with special blankets to maximize the transmutation by 14 MeV neutrons of uranium-238 to plutonium or thorium to uranium-233 for use as a fuel for fission reactors. Breeding fissile fuels has not been a goal of the US fusion energy program. This paper suggests it is time for a policy change to make the fusion breeder a goal of the US fusion program and the US nuclear energy program. The purpose of this paper is to suggest this policy change be mad… more

MHD compressor---expander conversion system integrated with GCR inside a deployable reflector

Description: This work originates from the proposal MHD Compressor-Expander Conversion System Integrated with a GCR Inside a Deployable Reflector''. The proposal concerned an innovative concept of nuclear, closed-cycle MHD converter for power generation on space-based systems in the multi-megawatt range. The basic element of this converter is the Power Conversion Unit (PCU) consisting of a gas core reactor directly coupled to an MHD expansion channel. Integrated with the PCU, a deployable reflector provides… more

Pay Equity - The Comparable Worth Issue: Equal Pay for Work of Equal Value; By What Standards and By What Means?

Description: This report discusses the term comparable worth issue, a "theory that jobs dominated by women may be valued less not because of skills required or job content, but because they are "women's jobs (page 1)." The report analyzes historical events and lawsuits that relate to the issue of comparable worth in the workforce.

Radiation damping of betatron oscillations

Description: The emission of synchrotron radiation damps the incoherent betatron oscillations of a pinched beam, causing its radius to shrink. However, the rate of shrinkage is small compared with the rate of expansion caused by scattering for typical propagation parameters.

SSC test lattices

Description: A set of eight test lattices for the SSC have been devised for such purposes as the investigation of the dependences of chromatic properties and dynamic aperture on the type, field, physical aperture and errors of the magnets, on the sextupole correction scheme, on the tunes and on the cell phase advances. They are distinguished from realistic lattices in that certain features of the latter are missing - most notably the crossing magnets that bring the two counter-rotating proton beams into col… more

Streak-camera recording of simultaneous optical and x-ray signals

Description: An S-1 optical streak camera with 10-ps (optical) temporal resolution simultaneously records reflected 1.06-..mu..m laser light and suprathermal (> 30 keV) x rays from laser fusion targets. To make these measurements, the camera x-ray sensitivity is increased 30-fold without significant loss of temporal resolution by increasing the effective slit width from the normal 50 ..mu..m to 1500 ..mu..m. The measurement system is described and sample data are presented.

Study of mechanisms of hydrogen diffusion in separation devices. Annual progress report, 1980-1981

Description: The main results are in the following 3 areas: (1) static and dynamic properties of the hydrogen diffusion model; (2) exact asymptotic solutions of the model; (3) new physics of the lattice hydrogen. The progress made during this period has been particularly significant. The hydrogen diffusion model has brought to light a number of puzzling features of hydrogen metal systems. These advances have made it possible now to begin to study some of the long-range objectives put forth in the initial pr… more

Why search for double beta decay

Description: Searching for neutrinoless double beta decay is the only known practical method for trying to determine whether neutrinos are their own antiparticles. The theoretical motivation for supposing that they may indeed be their own antiparticles is described. The reason that it is so difficult to ascertain experimentally whether they are or are not is explained, as is the special sensitivity of neutrinoless double beta decay. The potential implications of the observation of this reaction for neutrino… more
