An Investigation Of Broadband Current Preamplification For Obtaining Simultaneous High-Resolution Energy And Time Information From Nuclear Radiation Detectors, Joe Kenneth Millard

Doctoral Dissertations

In beginning the investigation of low noise current preamplification, noise-performance limitations of existing broadband current-amplifying stages are considered. Dominant noise sources of the general, shuntfeedback amplifier stage having both bipolar and field-effect transistor input devices are discussed. This discussion includes the reasons why optimum noise performance from this amplifier stage requires unavoidable signal integration. The integrating shunt-feedback configuration is commonly known as the charge-sensitive preamplifier. Criteria are developed for differentiating the output voltage pulse of the charge-sensitive preamplifier without degrading the signal-to-noise ratio. Subsequently, a new broadband, shunt-feedback amplifier is described having a current gain equal to the ratio of …

Application Of Positive Feedback Techniques To Charge-Sensitive Preamplifiers, Willaim Pinkston Albritton Jr.

Doctoral Dissertations

The application of positive feedback techniques to charge-sensitive preamplifiers for the purpose of improving their performance characteristics and versatility is considered. Improvements in sensitivity of charge gain in input capacitance, preamplifier output pulse rise-time, and ability to terminate long input cables are discussed. In each case, theoretical developments are carried out in order to determine the optimum positive feedback conditions. A practical charge-sensitive preamplifier design is discussed and the effects of applying positive feedback are delineated.

For the experimental preamplifier, the application of positive feedback resulted in a reduction in charge gain sensitivity to input capacitance changes of almost an …

Part A: Some Reactions Of Norbornene Oxide: Part B: Arylnorbornene Oxides, Thomas J. Gerteisen

Doctoral Dissertations

Part A: In this thesis research on the action of Grignard reagents with with norbornene oxide has been initiated and found to be of possible synthetic utility.

Part B: The structure of the product of the acid catalyzed dehydration of 2-p-anisylnorbornane-2, 3-cis-exo-diol in hydrochloric acid-tetrahy-drofuran has been reassigned. It was discovered, on the basis of further data, that the structure of the high melting solid was that of the dimer of the epoxide, a p-dioxane, rather than the epoxide itself. This change was proposed for many reasons. A near total nmr analysis of the compound …

Physiological, Cognitive And Motor Assessments Of Systematic Desensitization, Vey Michael Nordquist

Doctoral Dissertations

Twenty-four snake phobic subjects were randomly assigned to one of four conditions in order to test directly the mechanism underlying Systematic Desensitization therapy. Only those Ss who were treated with systematic desensitization showed significant reductions in physiological cognitive and motor estimates of fear. No Treatment Control and Hierarchy-Yoked Ss did not improve on a single measure after treatment. Relaxation-Yoked Ss did report significant decrements in fear after treatment, but their verbal fear decrement was not sustained when proximity to the phobic stimulus was increased. The results supported Wolpe's contention that systematic desensitization operates on the basis of …

The Development Of Voluntary Cardiovascular Control, Roger A. Kleinman

Doctoral Dissertations

Several lines of evidence have suggested that the normally involuntary status of the autonomic nervous system is due to a lack of discriminable afferent information to the central nervous system. This proposition has been implicitly supported by many behavioral studies all of which provided extrinsic feedback of cardiovascular performance in an attempt to produce learned cardiovascular control. In order to explicitly determine whether discrimination of afferent information from the heart facilitates subsequent learned heart rate control, therefore, the first experiment of this dissertation was performed. During the first phase of this experiment, human subjects were trained to discriminate their pulses, …

Quantitative Spark-Source Mass Spectrometric Techniques For The Simultaneous Determination Of The Lanthanide And Actinide Elements In Microgram And Sub-Microgram Transuranium Samples, Joel Avery Carter

Doctoral Dissertations

The work presented encompasses techniques developed for the analysis of certain rare earth and actinide elements in solutions containing highly radioactive transuranium elements. Advantage was taken of the high inherent resolution and sensitivity of the rf spark-source mass spectrometer in the development of qualitative and quantitative procedures where an analysis can be made on a total sample of <1 to 10 μg. Parameters for the Associated Electrical Industries' MS-702 spark-source mass spectrometer were adjusted so that mass-to-charge ratios in the range of 10 to 310 could be subjected to qualitative analysis. For quantitative assessment of impurities in a transuranium solution, relative sensitivity factors were established with respect to erbium, the internal standard, for rare earth elements and for thorium, uranium, neptunium, americium, curium, berkelium, and californium.

A special glove box was designed, fabricated, and used on the source end of the mass spectrometer so that samples of the transuranium elements could be run safely. Transuranium element with α-emitting radioactivity up to 10¹⁰ dpm were processed through the …
