Ultraviolet Spectrophotometric Determination of Osmium Tetroxide in CHCl3 by G. Goldstein (open access)

Ultraviolet Spectrophotometric Determination of Osmium Tetroxide in CHCl3 by G. Goldstein

A method was developed for the determination of osmium by measuring the absorbancy of osmium tetroxide in CHCl3. The osmium is first oxidized to the octavalent state and the osmium tetroxide which is formed is extracted selectively with CHCl3. The ultraviolet absorption spectrum of OsO4 in CHCl3 has a series of absorption bands with peak absorbancies at 282. 289, 297, 304 and 312 mu, and molar absorbancy indices of 1870, 1760, 1640, 1400 and 1000, respectively. For each wavelength the optimum concentration range for the determination of osmium was evaluated by the method of Ringbom. Only chloride and octavalent ruthenium interfere in the determination. By this method, from 0.4, to 3 mg of cesium can be determined with a coefficient of variation of 3 per cent.

Radiation Hazards from Recycled Reactor Fuel (open access)

Radiation Hazards from Recycled Reactor Fuel

The radiation hazards associated with recycled nuclear reactor fuels will greatly complicate the handling and refabrication of these fuels. This problem is most serious with U-233 and plutonium fuels where the presence of U-232 and the heavier isotopes of plutonium contribute energetic alpha, gamma, and neutron radiations at levels many times that from isotopically pure U-233 and Pu-239. This report summarizes present knowledge of the radiation hazards associated with recycled fuel and the additional data needed to make a thorough evaluation of these hazards.

Metastable States of Hyperfragments and the Anomalous Magnetic Moment of the Λ-Hyperon (open access)

Metastable States of Hyperfragments and the Anomalous Magnetic Moment of the Λ-Hyperon

"We want to point out that there is a possible method for determining the anomalous magnetic moment of the Λ from the observation of metastable states of hyperframents. There are two possible sources for the apparent difference of binding energies of a hyperfragment. One of these comes from the difference of Q values due to the decay into an excited and ground states of the residual nucleus. The other possibility will arise if there exists a metastable state of the decaying hyperfragment."

Double Crystal X-Ray Spectrometer for Study of Irradiated Materials (open access)

Double Crystal X-Ray Spectrometer for Study of Irradiated Materials

For some time, the need has been recognized for an X-ray diffraction unit applicable to studies concerning the crystallographic characteristics of pile irradiated materials. Except for studies involving specimens of low activity, it has been impossible in the past to investigate materials which emit intense beta and gamma radiations. The exact type and degree of irradiation damage to high activity materials has been largely a matter of theoretical conjecture. The object of this report is to describe an X-ray diffraction spectrometer that can be used to collect crystallographic data from irradiated materials.

Connection between adiabaticity and the mirror mode

The size of magnetic moment jumps of a particle in a long, thin equilibrium magnetic mirror field is shown to be related to the complex zeroes of the mirror mode parameter B + 4..pi..dP/sub perpendicular//dB. A consequence is that adiabaticity places a lower limit on ..beta.. than does the mirror mode.

Coherent betatron instability in the Tevatron (open access)

Coherent betatron instability in the Tevatron

The coherent betatron instability was first observed during the recent 1987-88 Tevatron fixed target run. In this operating mode 1000 consecutive bunches are loaded into the machine at 150 GeV with a bunch spacing of 18.8 /times/ 10/sup -9/ sec (53 MHz). The normalized transverse emittance is typically 15 ..pi.. /times/ 10/sup -6/ m rad in each plane with a longitudinal emittance of about 1.5 eV-sec. The beam is accelerated to 800 GeV in 13 sec. and then it is resonantly extracted during a 23 sec flat top. As the run progressed the bunch intensities were increased until at about 1.4 /times/ 10/sup 10/ppb (protons per bunch) we experienced the onset of a coherent horizontal oscillation taking place in the later stages of the acceleration cycle (>600 GeV). This rapidly developing coherent instability results in a significant emittance growth, which limits machine performance and in a catastrophic scenario it even prevents extraction of the beam. In this paper we will present a simple analytic description of the observed instability. We will show that a combination of a resistive wall coupled bunch effect and a single bunch slow head-tail instability is consistent with the above observations. Finally, a systematic numerical analysis …

Analytical and numerical evaluation of Landau cavities in the Fermilab Booster (open access)

Analytical and numerical evaluation of Landau cavities in the Fermilab Booster

Longitudinal coupled bunch instability has been observed in the Fermilab Booster at high intensity. It is a cause for concern due to its effect on the Tevatron collider performance. We study this phenomenon using initial value technique to correctly account for the underlying transient nature. Analytic result is obtained for any mode and comparison is made between ordinary harmonic potential and higher harmonic (Landau) cavity potential. A computer program is developed to facilitate the calculation. The result shows that the merit of Landau cavity is best realized in cases where the resonance is of a broad band nature. 5 refs., 4 figs., 3 tabs.

User's guide to the LLL BASIC interpreter. [For 8080-based MCS-80 microcomputer system]

Scientists are finding increased applications for microcomputers as process controllers in their experiments. However, while microcomputers are small and inexpensive, they are difficult to program in machine or assembly language. A high-level language is needed to enable scientists to develop their own microcomputer programs for their experiments on location. Recognizing this need, LLL contracted to have such a language developed. This report describes the result--the LLL BASIC interpreter, which operates with LLL's 8080-based MCS-80 microcomputer system. 4 tables.

Estimating Groundwater Concentrations from Mass Releases to the Aquifer at Integrated Disposal Facility and Tank Farm Locations Within the Central Plateau of the Hanford Site (open access)

Estimating Groundwater Concentrations from Mass Releases to the Aquifer at Integrated Disposal Facility and Tank Farm Locations Within the Central Plateau of the Hanford Site

This report summarizes groundwater-related numerical calculations that will support groundwater flow and transport analyses associated with the scheduled 2005 performance assessment of the Integrated Disposal Facility (IDF) at the Hanford Site. The report also provides potential supporting information to other ongoing Hanford Site risk analyses associated with the closure of single-shell tank farms and related actions. The IDF 2005 performance assessment analysis is using well intercept factors (WIFs), as outlined in the 2001 performance assessment of the IDF. The flow and transport analyses applied to these calculations use both a site-wide regional-scale model and a local-scale model of the area near the IDF. The regional-scale model is used to evaluate flow conditions, groundwater transport, and impacts from the IDF in the central part of the Hanford Site, at the core zone boundary around the 200 East and 200 West Areas, and along the Columbia River. The local-scale model is used to evaluate impacts from transport of contaminants to a hypothetical well 100 m downgradient from the IDF boundaries. Analyses similar to the regional-scale analysis of IDF releases are also provided at individual tank farm areas as additional information. To gain insight on how the WIF approach compares with other approaches …

Nuclear fusion driven by coulomb explosions of deuterium clusters (open access)

Nuclear fusion driven by coulomb explosions of deuterium clusters

We have examined the interaction of deuterium clusters with high intensity, ultrafast laser radiation. Upon irradiation a hot plasma is created with a sufficient temperature to produce nuclear fusion. We have seen that larger clusters produce more fusion neutrons than smaller clusters, consistent with a Coulomb explosion model. Fusion yield is currently limited by propagation effects. Using inter ferometric imaging we have examined the laser propagation and found that the laser energy is absorbed before it penetrates to the center (highest density region) of the gas jet.

Level Densities and Radiative Strength Functions in 170,171Yb

Level densities and radiative strength functions in {sup 171}Yb and{sup 170}Yb nuclei have been measured with the {sup 171}Yb({sup 3}He, {sup 3}He{prime}{gamma}){sup 171}Yb and {sup 171}Yb({sup 3}He,{alpha}{gamma}){sup 170}Yb reactions. A simultaneous determination of the nuclear level density and the radiative strength function was made. The present data adds to and is consistent with previous results for several other rare earth nuclei. The method will be briefly reviewed and the result from the analysis will be presented. The radiative strength function for {sup 171}Yb is compared to previously published work.

Proposed design of SAMUS (small angle muon spectrometer) toroid and its magnetic field calculation

Presently the D/null/ detector has three big toroidal magnets; one Central Toroid (CF) and two End Wall Toroids (EF). The EF toroids have central openings 72'' x 72''. Originally, this opening was meant for possible future end-plug calorimeters. Instead we are now designing Small Angle Muon Spectrometer (SAMUS) for the opening. The major component will be built at Serpukhov. The design of the toroid magnets and its magnetic field calculations is being done by exchanging information between Serpukhov and Fermilab. 2 refs., 4 figs., 1 tab.

Luminosity lifetime in the Tevatron (open access)

Luminosity lifetime in the Tevatron

Since the inauguration of colliding proton-antiproton operations in 1987, the Tevatron has exhibited luminosity lifetimes shorter than expected. During a typical colliding beam storage period, called a store, luminosity is calculated periodically by measuring the charge and emittances of each bunch. The growth of the transverse bunch emittances is the dominant cause of luminosity deterioration. Throughout, this period, the position spectrum of the bunches exhibited betatron signals larger than expected from Schottky noise. A model assuming externally driven betatron oscillations explains both the betatron signals and the emittance growth. A program is underway to improve the Tevatron luminosity lifetime. The abort kickers have been identified as sources of emittance growth, and some quadrupole power supplies are further candidates. Because the horizontal dispersion through the RF cavities is nonzero, RF phase noise has been investigated. Noise in the main dipole regulation circuit has also been studied. 13 refs., 4 figs.

Pelletizing/reslurrying as a means of distributing and firing clean coal (open access)

Pelletizing/reslurrying as a means of distributing and firing clean coal

Work in this quarter focused on completing (1) the final batch of pilot-scale disk pellets, (2) storage, handling, and transportation evaluation, (3) pellet reslurrying and atomization studies, and (4) cost estimation for pellet and slurry production. Disk pelletization of Elkhorn coal was completed this quarter. Pellets were approximately 1/2- to 3/4-in. in diameter. Pellets, after thermal curing were strong and durable and exceeded the pellet acceptance criteria. Storage and handling tests indicate a strong, durable pellet can be prepared from all coals, and these pellets (with the appropriate binder) can withstand outdoor, exposed storage for at least 4 weeks. Pellets in unexposed storage show no deterioration in pellet properties. Real and simulated transportation tests indicate truck transportation should generate less than 5 percent fines during transport. Continuous reslurrying testing and subsequent atomization evaluation were performed this quarter in association with University of Alabama and Jim Walter Resources. Four different slurries of approximately 55-percent-solids with viscosities below 500 cP (at 100 sec{sup {minus}1}) were prepared. Both continuous pellet-to-slurry production and atomization testing was successfully demonstrated. Finally, an in depth evaluation of the cost to prepare pellets, transport, handle, store, and convert the pellet into Coal Water Fuel (CWF) slurries was completed. …
