Abstract
Radio frequency (RF) plasma sources are a common tool for application and study, and of particular interest for inertial electrostatic (IEC) fusion. Computational analysis is often carried out using particle in cell (PIC) methods or finite difference time domain (FDTD). However, a more holistic analysis is necessary as the particle distribution is highly dependent on the fields created by the plasma source. Herein, an analysis of a particular planar RF coil with deuterium gas is provided which covers the fields and the particle behavior using first FDTD then PIC. Further applications are discussed as well as further directions for this study.

Augustin Griswold
Major: Physics
Augustin Griswold is majoring in Physics with a minor in Mathematics. He is a member of the Sánchez group in the subsection which works on Inertial Electrostatic Confinement fusion. He is a student in the Honors College, a McNair scholar, an undergraduate instructor, and an employee working in course development in the Physics department at PSU. In the past, Augustin has also worked in Jun Jiao’s lab focusing on development of novel spin valves for implementation in quantum computers. His research interests include plasma dynamics, nuclear fusion, and plasma modelling. Alongside this, Augustin believes in a more approachable and accessible reshaping of Physics curriculum in order to allow a wider range of people to become curious about the many topics in Physics. To meet this goal, he plans on completing a PhD in Physics and a postdoc in order to become a professor at a public institution to allow him to pursue his research and educational goals.
Faculty Mentor: Dr. Erik Sánchez
My work has traditionally involved fabricating new forms of microscopes that allow scientists to work on a smaller scale than ever before. While working at PSU I have designed, fabricated and published many papers on the development of these new microscope designs. After becoming a full professor, I decided to diversify into two other fields: a more educationally based direction and the novel energy research field of fusion
