Suggested Uses of Cycloidal-Trajectory Particle Spectrometers in Nuclear Research (open access)

Suggested Uses of Cycloidal-Trajectory Particle Spectrometers in Nuclear Research

From abstract: "The motion of a charged particle in a region of crossed electric and magnetic fields is discussed... Possible applications of such a system to various problems in nuclear research are suggested and it is shown to be possible in principle to measure the kinetic energy, mass, and ionic charge of various nuclear-reaction products and to separate various short-lived products for rapid examination. Two different devices are proposed. The application of the technique to investigation of the fission process is specifically discussed."

Proposal for a High-Current Discharge Tube With Capacitor (open access)

Proposal for a High-Current Discharge Tube With Capacitor

Abstract: This proposal describes a parallel-plate capacitor and the discharge tube with which it is hoped that implosion energies of 1000 eV can be given to deuterons by the pinch effect. The discharge tube is to be arranged so that no external series switch is required.

Initial Measurements on the Angular Distribution of Deuterium Plasma Produced by a Pulsed Spark Source (open access)

Initial Measurements on the Angular Distribution of Deuterium Plasma Produced by a Pulsed Spark Source

Abstract: "The deuterium plasma which is ejected by a 6000-ampere pulsed current through a rail-type spark source has a yield in the forward direction which is a factor of 5 to 10 greater than that in the perpendicular direction. This effect is believed to be due to the magnetic propulsion of the plasma."

Report on Shock Tube Experiments (open access)

Report on Shock Tube Experiments

Abstract: An investigation of ionization by shock waves in hydrogen has been initiated. The shock waves are produced in a 1-inch diameter glass pipe by a high-voltage spark at one end. Variables which will influence attainment of the maximum degree of ionization and ion temperature are described. Spectroscopic methods of measuring ion density and temperature are outlined, and improvements in the design of the shock tube are discussed.

On the Mechanism of Generation of Magneto-Hydrodynamic Whirl Rings in the Interior of the Sun and Their Relation to Sunspots, Faculae, Prominences, and Flares (open access)

On the Mechanism of Generation of Magneto-Hydrodynamic Whirl Rings in the Interior of the Sun and Their Relation to Sunspots, Faculae, Prominences, and Flares

Abstract: "A possible mechanism for the generation of magneto-hydrodynamic whirl rings near the center of the sun is described. The organic relation of the reflection of these whirl rings at the surface of the sun to the cooling of sunspots, orientation, and polarity sequence of sunspots, prominences, flares, and faculae is delineated."

Factors Affecting the Concentration of TBP Plant Wastes (open access)

Factors Affecting the Concentration of TBP Plant Wastes

Introduction: "The problem of determining the properties and necessary controls on the TBP Plant waste disposal to eliminate transport line plugging and to permit higher concentration prior to return of this to the tank farms was studied. A report of preliminary findings was made to L. W. Finsh on January 31, 1953. This report compiles information in the aforementioned report and findings since its issuance. Previous studies related to this problem are summarized in the U. R. Technical Manual, HW-19140."

Investigation of Explosive Characteristics of Purex Solvent Decomposition Products (Red Oil) (open access)

Investigation of Explosive Characteristics of Purex Solvent Decomposition Products (Red Oil)

Abstract: "Laboratory production of an explosion between UNH and "red oil" under calcination conditions has been accomplished. Attempted production of a vapor phase explosion was unsuccessful below 150-160 C. Since such severe conditions are necessary to obtain an explosive reaction, it appears that present Purex plant design is adequate to avoid explosive conditions."

General Flattening and Power Curves (open access)

General Flattening and Power Curves

Introduction: "In the evaluation of pile designs it is necessary to know how the production varies with the number of tubes. It has been possible to solve the problem in terms of some general parameters whose values may be quickly computed for any specific design when the pertinent information is available."

The Ratio of Alpha to Beta Activity of Natural Atmospheric Radioactivity (open access)

The Ratio of Alpha to Beta Activity of Natural Atmospheric Radioactivity

Abstract: The alpha to beta ratio of naturally occurring radioactivity in the air has been investigated. The study has concerned itself primarily with radon daughter products collected on filter-paper samples from the time equilibrium has been established on the paper through elapsed times during which radioactive counting is normally accomplished. Calculations showing the change in this ratio of activities during the above period are presented. From this work it appears that the observed constancy of ratio does have theoretical justification and that departures in alpha-to-beta ratio would be a usable approach to the detection of long-lived alpha or beta radioisotopes in the atmosphere.

Reclamation of Contaminated Kinney and Diffusion Pump Oils and Removal of Uranium Therefrom (open access)

Reclamation of Contaminated Kinney and Diffusion Pump Oils and Removal of Uranium Therefrom

Abstract: Test distillations were made with Kinney and diffusion pump oils under vacuum in order to determine accurately the temperature range over which satisfactory distillate may be collected. Also recommendations are made as to the most advisable type of heating equipment necessary to produce the required heat and maintain the desired temperature. In addition, several important refinements in the distillation equipment were checked for operational characteristics and for their efficiency in aiding the production of uranium-free distillates.

Radiometric Analysis of Thick Samples (open access)

Radiometric Analysis of Thick Samples

Introduction: Measurements of polonium content in solids are usually performed by dissolving the material and preparing a thin sample which can be measured with one of the available instruments. A measurement of the radiation emerging from the thick sample should be sufficient to evaluate the polonium content. For this reason a calculation has been performed and the results have been compared with those obtained by the thin sample method. Obviously this proposed method using thick samples would be faster.
