Summary of Research

As a PhD student in the University of Illinois Department of Nuclear, Plasma, and Radiological Engineering, I plan to pursue graduate research in the area of plasma science and nuclear fusion, with particular emphasis on the study of plasma-material interactions. I will work under Dr. David Ruzic within the Center for Plasma Material Interactions (CPMI) at the university to study the interactions of plasmas with the surrounding materials found in engineered systems. Existing research efforts at CPMI include the use of liquid lithium as a plasma-facing material, which is similar to past research efforts undertaken at the Sandia National Laboratory. The new HIDRA tokamak facility that is under construction at the University of Illinois will provide a unique opportunity to study plasma-material interactions and develop improved plasma facing components (PFC). Research in the design of liquid metal systems—such as a liquid lithium PFC—also has a number of other applications beyond magnetic confinement fusion. These applications include the development of improved techniques for the manufacture of nuclear fuel cladding and in the high-heat flux cooling of electronics.
