Design and Construction of an Atmospheric Pressure Imploding Thin-Film Theta Pinch Device as an Atomization Source for Atomic Emission Spectroscopy

Blanchard, Thomas W. 22 January 2016 (has links)
<p> 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, 1.80&micro;F 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 <i>worst case scenario.</i> The design uses 4&rdquo; by 0.75&rdquo; 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.</p>
