A Determination of the Bothe Depression Factor for Discs in Water

A Determination of the Bothe Depression Factor for Discs in Water

Date: August 1950
Creator: Patton, Bob
Description: The purpose of this work is to determine experimentally the depression of the neutron density by a detecting foil. The depression factor is known as the "self-shading" of the foil.

Analyzing Magnet System for the Electrostatic Accelerator

Analyzing Magnet System for the Electrostatic Accelerator

Date: August 1954
Creator: Young, Thomas E.
Description: This thesis describes the design and construction of a linear accelerator, specifically, a positive-ion source, a high voltage supply, an accelerating column, and the necessary associated vacuum system.

Design and Testing of a Positive Ion Accelerator and Necessary Vacuum System

Design and Testing of a Positive Ion Accelerator and Necessary Vacuum System

Date: August 1953
Creator: McKay, Vern A.
Description: This thesis is a study of the design and testing of a positive ion accelerator and necessary vacuum system.

Variational Wave Function for Sodium

Variational Wave Function for Sodium

Date: August 1953
Creator: Smith, Daniel Montague
Description: The practical method of applying the variation principle to the calculation of the energy of an atom demands a trial function which contains variable parameters. The previous work done using this approach was based on the use of some combination of hydrogenic wave functions containing parameters inserted in appropriate places. The present calculation of the energy of the eleven-electron atom has been brought about using this method.

Foil Depression Factors for Disc-shaped Detectors

Foil Depression Factors for Disc-shaped Detectors

Date: June 1954
Creator: Gallagher, Tom Lewis
Description: The generalized data which are presented in this thesis are the culmination of the determination of the foil depression factor using oblate spheroidal coordinates.

Neutron Density Depression Due to an Oblate Spheroidal Detector

Neutron Density Depression Due to an Oblate Spheroidal Detector

Date: January 1954
Creator: Trammell, Margaret Ruth
Description: In this paper, two projects have been undertaken. First, Workman's calculations have been checked to a higher degree of approximation to determine the accuracy of his method. Second, a new set of boundary conditions has been developed for obtaining solutions of the neutron diffusion equation which do not depend on the solution of the equation inside the detector.

Operation and Control of a Radiofrequency Ion Source

Operation and Control of a Radiofrequency Ion Source

Date: August 1953
Creator: Paulissen, George T.
Description: This thesis examines the operation and control of a radiofrequency ion source.

A Method for Calculating Foil Depression Factors

A Method for Calculating Foil Depression Factors

Date: June 1953
Creator: Workman, Billy J.
Description: As disc-shaped detectors are one of the primary means of measuring the neutron density, a better solution is desirable if the error due to the depression factor is to be made negligible. In this paper, an attempt is made to solve this problem in the oblate spheroidal co-ordinate system which most nearly describes the disc-shaped detector, so that solutions may be obtained that describe depression factors for detectors of varying thicknesses and radii.

Quaternion Representation of Crystal Point Groups

Quaternion Representation of Crystal Point Groups

Date: August 1959
Creator: West, Richard Harrison
Description: The physical behavior of crystalline solids is very closely related to the internal symmetry of the crystal structure. For this reason it is desirable to represent mathematically this symmetry in such a way that the actual physical problems can be handled as they arise. In the case of this thesis the research has been guided by a list of desired properties for such a representation. No claim is made that the list is complete.

Magnetic Resonance of Protons in the Earth's Magnetic Field

Magnetic Resonance of Protons in the Earth's Magnetic Field

Date: August 1959
Creator: Crosby, Richard Hill
Description: The purpose of the work reported here was to determine the feasibility of applying the nuclear induction technique of Bloch to the direct observation of nuclear magnetic resonance in the very weak magnetic field of the earth.
