Federal Grant Award Summary

West Virginia University Research Corporation received a $633,833 Project Grant award from the National Science Foundation's Division of Physics (CFDA 47.049, Mathematical and Physical Sciences program) effective May 15, 2026, through April 30, 2029. The award supports development of novel quantum sensing diagnostics for investigating plasma-boundary interactions, specifically focusing on non-perturbative mapping of inverted sheaths in low-temperature plasmas. The project will employ laser-induced fluorescence and quantum beat spectroscopy techniques to obtain high-fidelity, spatially-resolved measurements of ion velocity distributions, electric fields, and potential profiles without intrusive probes. Research activities will examine how electron emission from surfaces modifies ion flows and electric field structures, with particular emphasis on strongly emitting boundaries and transitions between classical, space-charge-limited, and inverted sheath configurations.

In addition to advancing fundamental understanding of plasma-surface interactions with applications to semiconductor manufacturing, spacecraft propulsion, and fusion energy research, the award supports workforce development and educational outreach components. Deliverables include training of graduate and undergraduate researchers at West Virginia University, development of a new advanced undergraduate laboratory course module in plasma physics, and expanded educational opportunities and outreach initiatives targeting students from rural and underserved communities across West Virginia. These integrated research and educational activities align with the Mathematical and Physical Sciences program's emphasis on advancing scientific knowledge while strengthening the nation's scientific enterprise through the next generation of researchers.
