A Vacuum Tube for an Electrostatic Accelerator

The purpose of this study has been to design a prototype accelerating tube, to determine the correct point shape and spacing needed to produce corona current along the tube for the case of negative-point-to-positive-plane discharge, and to study the voltage-gradient characteristics of short sections of the tube when they were evacuated to a low internal pressure.

Magnetically Driven Instabilities in Gas Discharges (open access)

Magnetically Driven Instabilities in Gas Discharges

In the present experiment a gas discharge plasma generator was designed and constructed and a search was made for evidence of a plasma instability due to the influence of an externally applied magnetic field. The evidence for such an unstable mode of operation is too indirect to make a possible conclusion, but an approach to more certain identification will be indicated.

Electron Transport in Bismuth at Liquid Helium Tempratures (open access)

Electron Transport in Bismuth at Liquid Helium Tempratures

To obtain information on the band structure of bismuth, galvanomagnetic potentials were measured in a single crystal at liquid-helium and liquid-nitrogen temperatures. These measurements were analyzed for information on the different carriers, particularly for the existence of a high-mobility band of holes.

A Calculation of the Kaon-Neutron Scattering Cross Section (open access)

A Calculation of the Kaon-Neutron Scattering Cross Section

The purpose of this investigation was to study the scattering processes of K+ mesons with neutrons. In order to do such a study one must first make certain basic assumptions about the type of interaction involved and then proceed to calculate physically meaningful qualities which describe the processes. Thus, the problem is this: assuming the validity of Feynman's rules for these strongly interacting particles, calculate the differential and total scattering cross sections for the interaction of scalar K+ mesons and neutrons.

Homogeneous Canonical Formalism and Relativistic Wave Equations (open access)

Homogeneous Canonical Formalism and Relativistic Wave Equations

This thesis presents a development of classical canonical formalism and the usual transition schema to quantum dynamics. The question of transition from relativistic mechanics to relativistic quantum dynamics is answered by developing a homogeneous formalism which is relativistically invariant. Using this formalism the Klein-Gordon equation is derived as the relativistic analog of the Schroedinger equation. Using this formalism further, a method of generating other relativistic equations (with spin) is presented.

A Study and Critique of the Mean Position Concept in Relativistic Wave Mechanics (open access)

A Study and Critique of the Mean Position Concept in Relativistic Wave Mechanics

The basic concept to be used in studying the question of one-particle interpretations of relativistic wave equations is that of observables and operator representations that are different from the more usual classically motivated observables and representations. In particular, the concept of a mean-position observable will be used to determine to what extent the one-particle "problems" can be resolved.
