Modeling, Design and Characterization of Capacitive Discharge Systems for the Production of Pulsed Magnetic Fields Suitable for the Magnetic Modification of Plasmas for Atomic Emission Spectroscopy

Abstract

The development of capacitive discharge instrumentation for studying the effects of pulsed magnetic fields on analytical plasmas requires careful matching of the electrical properties of both the discharge source as well as the load coil used to expose the plasma to the magnetic field. In this poster, we will present the methods used in our lab for designing, modelling and characterizing these magnetic field discharge systems, with special emphasis on magnetic field/laser plasma interactions and the development of a theta-pinch plasma gun source. Specifically, our magnetic field production/theta-pinch modelling program has been re-written as a macro program (running within Excel). Experimental results from new coils designed with this program will be presented and compared with the results predicted by the modeling macro.
