Summary
This award supports development of a novel quantum sensing diagnostic for studying plasma properties near solid surfaces. Plasmas are used in technologies that matter in everyday life, from computer chip manufacturing, to spacecraft propulsion systems, to potential new energy production facilities. When a plasma touches a solid surface, a very thin but complex electrical layer called a plasma sheath is formed. The properties of such sheaths and the interaction between the plasma and a surface are not yet fully understood. This project will develop new laser-based measurement methods to study
