This site details my undergraduate honors thesis research on laboratory plasmas. My project involves comparing computer simulations of radiative processes in plasmas to actual emission spectra from the Swarthmore Spheromak Experiment (SSX). SSX is currently being used to study magnetic reconnection during the merging of two spheromaks (a spheromak is a donut-shaped plasma configuration that relaxes to an equilibrium confined entirely by its own magnetic fields). I'll be focusing on data from two diagnostics: a vacuum ultraviolet (VUV) monochromator, and a low-resolution soft x-ray detector (SXR). The data are compared to model spectra calculated for plasmas with a range of temperatures, densities, and compositions in order to place constraints on the actual properties of the SSX plasma. Most of my simulations will utilize PrismSPECT and other software by Prism Computational Sciences. Research on plasma properties and magnetic reconnection has applications to a variety of branches of science, including solar physics and nuclear fusion research.
