This thesis presents a computational study of charge exchange (CX) interactions between highly charged ions (HCIs) and neutrals as well as an overview of a planned experimental study of these CX interactions. The flexible atomic code (FAC) was used to compute energy levels, CX cross sections, and X-ray emission spectra resulting from CX between HCIs (Ne9+, Ne10+, Mg11+, Mg12+, Si13+, Si14+, P14+, P15+, and Fe16+) and neutrals (He, H2, and H). The results were compared to existing data in the literature when available, and are in good agreement overall. In addition, thermal evaporation via a resistive oven was investigated as a method for loading elements that exist as solids at STP into the Clemson University electron beam ion trap (CUEBIT). To do so, a resistive oven was constructed, and a quartz crystal microbalance (QCM) was used to measure the neutral beam density resulting from the oven at various temperatures. The results indicate that a resistive oven is a viable method for loading the CUEBIT.
