Magnetic Acceleration of a Plasma by a Rail Source

Description: Abstract: "Two parallel wires close together with an arc between them form a hairpin-type of current configuration which should magnetically propel the plasma of the arc. By the time-of-flight measurements with probes it has been demonstrated that directed translational energies of 290 ev can be imparted to deuterons in a plasma produced by a high-current pulsed arc at the tips of two titanium wires loaded with deuterium. It is believed that three deuterons are actually magnetically propelled."

Proposal for a High-Current Discharge Tube With Capacitor

Description: 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.

An Immobilized Plasma in a Nonuniform Field : (IBM Machine Code Title "PLANOUNF1")

Description: Abstract: "The self-consistent equations have been found for a plasma which lies in a mainly unidirectional magnetic field, which has a circular symmetry and which has a harmonic variation in the direction of the magnetic field. The equations have been solved in two cases, 1) where the harmonic variation of the field is finite and the plasma is weak, and 2) where the plasma is strong but the harmonic variation of the field is weak. The configurations thus found can form an important starting po… more

The Effect of Coenzyme A on the Metabolic Oxidation of LabeledFatty Acids: Rate Studies, Instrumentation, and Liver Fractionation

Description: The effect of pantothenic acid deficiency on the rate of C{sup 14}O{sub 2} excretion and on distribution of radioactivity in liver fractions has been studied in rats given sodium acetate-2-C{sup 14} and sodium heptanoate-7-C{sup 14} The rate of excretion of breath C{sub 14}O has been measured by use of a method in which a sensitive ionization chamber and electrometer directly and continuously record carbon-14 excretion. The labeled fatty acids are more rapidly metabolized to C{sup 14}O{sub 2} i… more

PRODUCTION OF ELECTROLYTIC THORIUM CELL FEED BY A WET CHEMICAL METHOD. Process Report

Description: In order to produce a substantially oxide-free chloride. a specialized technique, based on the chemical characteristics of the ammonium thorium chloride complexes, has been found optimum. The procedure involves the formation of a solution of thorium chloride and ammonium chloride, evaporation of the solution to form a hydrated ammonium thorium chloride complex, dehydration of the complex by low-temperature drying, and ignition of the complex, after inter-mixture with an alkali chloride, to remo… more

Thermionic Properties of Uranium Wire

Description: Three independent measurements of the work function of uranium have been reported. The values obtained were were made with uranium wire and since, as shown by the authors, uranium is very readily oxidized at pressures of 10/sup -7/ mm Hg to give a relatively non-volatile oxide, one surmises that some of these determinations were subject to error because of vacuum conditions. Attempting to investigate the validity of this criticism, the authors have measured the thermionic properties of a uraniu… more
