A High Performance Detector Electronics System For Positron Tomography, John Clifton Moyers, Jr.
Masters Theses
Positron Emission Tomography (PET) has been a very useful laboratory tool for the noninvasive study of dynamic physiological processes within the human body. Its clinical worth in cardiology, neurology, and oncology has been verified for well over a decade. Only with the most recent introduction of high performance analog and VLSI digital components yielding higher scanner resolutions at reduced costs, has clinical PET truly become a reality. The High Performance Detector Electronics System presented here represents indubitably the most advanced processing system available in the clinical PET market.

Development Of The High Vacuum Steady-State Orbitron Maser, Mark S. Rader
Masters Theses
The Orbitron MASER is a device which can be used to generate R.F. radiation. This device has been operated for many years as a gas filled pulsed device. This thesis describes a brief history, design and operation of several steady-state, hot cathode Orbitron MASER. It also touches on a pulsed Orbitron MASER and the effects the hot cathode has on the radial electric field profile. A detailed derivation of emission frequency, gain and saturation is given in Appendix.
