Investigation Of Penetrating Cosmic-Ray Showers In Water, George William Rollosson

Physics & Astronomy ETDs

In this investigation, some of the properties of the radiation which produces penetrating showers in its passage through matter are studied. Geiger techniques are used to measure the average distance over which the neutral radiation produces one penetrating shower. This distance, called collision length, is measured in water...

The collision length, on the other hand, is measured by placing the material near the apparatus and measuring the mean distance in which one shower is produced and eliminating from the observation any penetrating showers which may be produced subsequently either (a) by the original particle or (b) by the secondaries from …

An Experimental Investigation Of The Dead Time Of Geiger-Mueller Counters, Peter H. Jessner

Physics & Astronomy ETDs

As ever more sensitive and precise experiments are being performed with Geiger Counters, especially in cosmic ray research, the resolving power of these instruments assumes an ever increasing importance. With the present perfection of electronic circuitry, this resolving time has become largely a function of the dead time of the Geiger counter tube itself. It was therefore proposed to investigate methods of reducing this dead time. Only self-quenching counter tubes had to be considered in this connection since the dead time of all other types of Geiger counters is inherently longer.

A Sensitive Electronic Photometer Employing Negative Feedback, John Lee Pack

Physics & Astronomy ETDs

Purpose of the Instrument

The instrument to be described in these pages was tentatively intended to be used for the purpose of scanning the night sky automatically for investigations of the zodiacal light. It was to detect light below the noise level of a photomultiplier tube, to have linearity up to signals 100 times greater than the noise level, and to have a response time of about 10-4 seconds.

The Elastic Scattering Of Deuterons By Deuterons, Richard John Runge

Physics & Astronomy ETDs

The concern of this work is the calculation of elastic scattering of deuterons by deuterons. The solution of the problem will be given in the usual center of mass system of coordinates, the conversion of results from this to the laboratory system being standard. Since the deuteron itself consists of a neutron and a proton, the problem is thus one of four bodies. The nuclear three body problem of the scattering of a neutron by a deuteron has been treated by previous authors and we will have occasion to employ methods used by these authors extending them to the four …

Enrichment Of Tin Activity Through The Szilard-Chalmers Separation, Herta W. Spano

Chemistry and Chemical Biology ETDs

It was the purpose of this investigation to utilize the Szilard-Chalmers reaction in order to prepare tin solutions of high specific activity.

Tetraphenyl tin was chosen for the target compound. It is a white, crystalline solid of excellent thermal stability. No data have been reported in the literature on the rate of exchange between inorganic forms of tin and tetraphenyl tin but it seemed highly probable that this exchange would be very slow. Tetraphenyl tin is soluble in various organic solvents but insoluble in water, and this suggested solvent extraction as a possible means of separation of the activated tin …

Derivatives Of M-Xylene, Henry J. Muller

Chemistry and Chemical Biology ETDs

Since m-xylene of 95-98% purity has recently become available from petroleum, this is an appropriate time to prepare an examine its derivatives. Isophtalic and m-toluic acids can be prepared from the hydrocarbon. The purpose of this work was to prepare imidazolines from these acids

Geology Of The Pre-Cambrian Rocks Of The Northern End Of The Sandia Mountains, Bernalillo And Sandoval Counties, New Mexico, Philip T. Hayes

Earth and Planetary Sciences ETDs

Most of the pre-Cambrian metamorphic rocks of the northern end of the Sandia Mountains crop out on and adjacent to a prominent spur, called the Rincon, which lies to the west of the main mountain mass. These metamorphic rocks which consist of quartzite, schist, and greenstone are considered to be the result of moderate regional metamorphism of clastic sedimentary rocks and possibly some basic flows and stills. These rocks are here tentatively named the Juan Tabo sequence and are Archeozoic or early Proterozoic age. The Sandia granite, which lies to the east and south of the Juan Tabo sequence, was …

A Differential Electronic Photometer And Polariscope With Negative Feedback, William Rogers

Physics & Astronomy ETDs

In connection which a program of research in the physics of the atmosphere, a need has arisen for a sensitive differential photometer which would be adaptable to balloon-borne operation. This paper describes a prototype of such an instrument. The present photometer is constructed for preliminary investigations to be carried out in the laboratory, but with light weight components used in the design except for the power supply and the main structural frame. Consideration is given to these latter features to the extent that the entire equipment is designed for operation from power sources which can be directly replaced by small …

An Experimental Investigation Of A Light Weight High Voltage Power Supply, James F. Tribby

Physics & Astronomy ETDs

This investigation is directed toward the development and design of an electronic high-voltage power supply. The method consists of obtaining a direct current of low intensity by periodically charging by means of a primary battery a group of capacitors in parallel combination and discharging them electronically in series. A stimulus to this investigation is provided by the need for a light-weight electronic current source operating at moderately high voltages which is stable and capable of maintaining a constant current of low intensity over a wide range of variation of the potential from a primary battery. In addition, a power supply …

The Variation Problems Of Weierstrass-Bliss And Radon, Douglas M. Gragg

Mathematics & Statistics ETDs

Problems of the Calculus of Variations are generalizations of the familiar minimum problems treated in the differential calculus. The relationships between the ordinary minimum problems of the calculus and the generalizations dealt with in the Calculus of Variations is possibly best seen by examining the general Hilbert-Moore minimum problem, and the special examples of such problems formulated in the table below.
