Columbia Scaling Circuits

Description: Abstract: "The advantages of high scaling ratios in counting random pulses are discussed. The mechanism of the basic circuit used in the Columbia University scaling circuits is described. The difficulties experienced in the performance of the earlier circuits are indicated and modified circuits to eliminate these difficulties are given. Precautions that must be observed in carrying out the constructional details are suggested. The complete circuit and specifications are given in detail for a Scale of 128 for use with linear-amplifier systems" (p. 1).

Investigation of Subsurface Isorad Methods, Temple Mountain, San Rafael District, Utah

Description: From abstract: The subsurface isorad method is an attempt to locate areas favorable for uranium ores by the use of contour maps which show localities having greater radioactivity. The construction of isorad maps entails the measurement of the area under the curve of a gamma-ray logo The figures obtained indicate relative amounts of gamma radiation and are used to locate the isorad contours. This work was started at Temple Mountain in the San Rafael Swell area during the spring of 1952. The purpose of this investigation is to determine the most effective and economic hole spacing for subsurface isorad work.

Geological Investigation of Mexican Cry Mesa, Lukachukai District, Arizona with Diamond Drilling Recommendations

Description: Abstract: The Salt Wash member of the Jurassic Morrison formation of Mexican Cry Mesa, Lukachukai District, Arizona, was examined to determine size, grade, and distribution of contained carnotite deposits and the possibilities of developing reserves by exploratory drilling. Only three occurrences of carnotite-bearing sandstone were found in 17 miles of rim outcrop. Limited drilling is recommended in the vicinity of these exposures.

The Determination of Uranium by Potentiometric Titration with Ferric Sulfate

Description: Abstract: "A method for the potentiometric titration of uranium with ferric sulfate is described. This method provides a rapid and accurate way of determining the element in solutions free from interfering ions. Application of the method to analysis of pure uranium compounds and to uranium recovered from contaminated solutions by suitable procedures is briefly discussed."

Flux Distribution - Converter Reactor

Description: From introduction: "A simplified calculation has been carried out in order to gain some insight into the flux distribution, peak to average power density, efficiency of a catching blanket and the effect of a reflector in the proposed converter reactor."

Gas Titration Methods for Uranium Hexafluoride

Description: This report studies the reactions between gaseous uranium hexafluoride and several gaseous reagents for possible analytical application that has been underway while using a buggy designed for gaseous titration studies. This study primarily focuses on methods to analyze gases containing uranium hexafluoride and physically absorbed uranium hexafluoride.

An Exact Analysis of Limited Plane Plasma in a Magnetic Field

Description: Introduction: "Prior analyses of a plasma in a magnetic field have been limited, as far as the writer is aware, to cases in which the relative change in field over the orbital distance and the relative change in ion concentration are both small, or in which the relations have been viewed in a purely hydrodynamical way. The first approach excludes cases which can be of considerable interests, for it fails near a plasma edge. The second loses all sight of the structure imposed by the orbital motions."

Progress Report - Project 31: Vapor Phase Chlorination of TO₃

Description: "This work is a continuation of an investigation begun in January, 1945, on a laboratory study of various methods for the chlorination of TO3. The work carried out this month deals entirely with gas phase chlorination, the liquid phase chlorination of TO3 having been turned over to Miss Hubbard. Gas phase chlorination of TO3 by means of CCl4, S2Cl2, SOCl2, SO2Cl2, and Cl2 have been carried out under varying conditions in the several different types of reactors."

Resonance Absorption of Thorium

Description: Abstract: Cadmium ratios for very thin (neutron and beta-wise) foils of thorium, gold, vanadium and indium have been measured in the glory hole of the WBNS. These cadmium ratios, together with the known thermal cross sections and a given calculated resonance integral for gold, were used to evaluare the resonance integrals of thorium, vanadium, and indium.

Dissolution of NaK

Description: Abstract: "A rapid yet safe method for the dissolution of sodium-potassium alloys prior to chemical or instrumental analysis has been devised. The alloy is submerged beneath the surface of an inert organic reagent and dissolved at a controlled rate by adding methanol drop-by-drop. A blanket of inert gas is maintained over the reaction flask. The procedure has been successfully used to dissolve samples of NaK in the range of 0.05 to 25 grams."
