• Characterization of a piezoelectric transformer plasma source 

    Hutsel, Brian T. (University of Missouri--Columbia, 2012)
    The piezoelectric transformer plasma source (PTPS) is a compact RF driven plasma source developed for near-space and microspacecraft propulsion. The PTPS uses the mass transfer of emitted charged particles from the plasma ...
  • Characterization of ion sources for compact accelerator neutron production 

    Baxter, Emily (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 ...
  • Design and simulation of a compact radiating system for high power microwaves in the 4 to 6 GHz range 

    Becker, Erik C. (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 ...
  • The ferroelectric plasma thruster 

    Kemp, Mark A., 1980- (University of Missouri--Columbia, 2008)
    Micropropulsion is an enabling technology for microspacecraft. As requirements for microspacecraft missions become more demanding, so do the requirements for micropropulsion. Therefore, existing technologies require ...
  • Flashover prevention on polystyrene high voltage insulators in a vacuum 

    Benwell, Andrew L., 1980- (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 ...
  • A high voltage piezoelectric transformer for active interrogation 

    Benwell, Andrew L., 1980- (University of Missouri--Columbia, 2009)
    A resonant piezoelectric transformer circuit was developed for high voltage generation. The goal of this project was to produce 100 kV with a reasonably sized piezoelectric crystal. Several mechanisms leading to less than ...
  • Investigation and optimization of a high voltage piezoelectric particle accelerator 

    Gall, Brady B. (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. ...
  • Laser target triggering of gas switches 

    Sullivan, Dustin L. (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 ...
  • Parametric investigation on thrust development of a piezoelectric transformer plasma propulsion system 

    Olson, Karl M. (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 ...
  • Plasma and Monte Carlo modeling of a psuedospark x-ray source 

    Hughs, Alec (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, ...
  • Runtime and jitter of a laser triggered gas switch 

    Hutsel, Brian T. (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. ...
  • Theoretical investigation of a laser triggered spark gap 

    Worts, Eric (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 ...
