Dissertation/Thesis Abstract

Design and Construction of an Atmospheric Pressure Imploding Thin-Film Theta Pinch Device as an Atomization Source for Atomic Emission Spectroscopy
by Blanchard, Thomas W., M.S., Southern Illinois University at Edwardsville, 2015, 98; 1606629
Abstract (Summary)

A direct solid sampling device has been developed using a theta pinch configuration to generate a pulsed plasma at atmospheric pressure. Energy from a 20kV, 1.80µF capacitive discharge system is to inductively couple with the sacrificial aluminum thin film and produce a cylindrical plasma. Electrical simulations of the main discharge circuit were analyzed to determine the necessary circuit components that would withstand the worst case scenario. The design uses 4” by 0.75” copper stock at varying lengths to make the transmission lines and must also accommodate a spark gap switch and Rowgowski coil into the design. The 5.5 turn prototype coil design is used in initial testing to examine behavior of the system when discharged.
