Theoretical investigation of a laser triggered spark gap
(University of Missouri--Columbia, 2005)
A model of a spark gap used as a shorting switch in a Blumlein pulse power system has been developed. The model is separated into a pre-breakdown kinetic model and a post-breakdown fluid model. The kinetic model is used ...
Flashover prevention on polystyrene high voltage insulators in a vacuum
(University of Missouri--Columbia, 2007)
Increasing performance of vacuum insulator barriers is a common goal in large pulsed power systems. Insulator performance is continually being improved while new methods are developed. Triple point shielding techniques ...
Optically enhanced nano-forest cathodes
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Optically enhanced nano-forest cathodes are electron sources developed for high power devices. The principle of cathode operation is based on coherent ...
Runtime and jitter of a laser triggered gas switch
(University of Missouri--Columbia, 2008)
The University of Missouri has studied parameters affecting the runtime and jitter of a laser triggered gas switch. Experiments tested a variety of switch parameters including percentage of self-break and charge voltage. ...
Laser target triggering of gas switches
(University of Missouri--Columbia, 2008)
Laser target triggering has been investigated at the University of Missouri as a method to reduce the laser energy required to trigger a laser triggered gas switch. Laser targets were solid materials embedded into the ...
Hefner model parameters for power IGBTS under pulsed power conditions
(University of Missouri--Columbia, 2010)
While the power insulated gate bipolar transistor (IGBT) is used in many applications, it is not well characterized under pulsed power conditions. This makes the IGBT difficult to model for solid state pulsed power ...
Parametric investigation on thrust development of a piezoelectric transformer plasma propulsion system
(University of Missouri--Columbia, 2013)
The PTPS-MT consists of a RF driven lithium niobate piezoelectric disc operating as a high voltage step-up transformer to ionize and accelerate plasma in a single self-contained package. Operation of the PTPS-MT is done ...
Design and simulation of a compact radiating system for high power microwaves in the 4 to 6 GHz range
(University of Missouri--Columbia, 2011)
As high power microwave technologies have advanced, demands have called for sources and radiators to become more compact. The University of Missouri has designed and simulated a compact radiating system for a compact virtual ...
Characterization of ion sources for compact accelerator neutron production
(University of Missouri--Columbia, 2011)
Compact neutron interrogation systems are a good candidate for use in active interrogation systems when large scale active or passive interrogation systems are not ideal. Field emitter arrays and plasma ion sources could ...
Investigation and optimization of a high voltage piezoelectric particle accelerator
(University of Missouri--Columbia, 2012)
This thesis contains analysis of the piezoelectric effect as a means to produce high voltage. The goal of this analysis is to determine if piezoelectric transformers can be used effectively in compact x-ray source applications. ...
Plasma and Monte Carlo modeling of a psuedospark x-ray source
(University of Missouri--Columbia, 2011)
A pseudospark x-ray source, for application in portable medical imaging, has been simulated at the University of Missouri. This device would allow for deployment in many venues such as emergency rooms, doctors' offices, ...
