Diagnostics and Sensors - NCPST

Diagnostics and Sensors

NCPST develops and applies advanced plasma measurement techniques for detailed fundamental investigations as well as smart process monitoring and control technologies.

About the Research Area

Plasma diagnostics are important for measuring and monitoring species, mechanisms and for process control. These, often most powerful when combined with simulations, provide understanding and insight of the plasma environment. This understanding is a key element in the development of plasma control strategies and solutions for technological development. Sensing technologies are important for real time monitoring of processes.
Diagnostics in the plasma environment are not trivial and are under continuous development as knowledge and technology advances. Advanced diagnostic techniques often exploit new laser technologies, coupled with atomic and molecular physics understanding. Electrical plasma emission is also a powerful tool for plasma sensing and process control. Combining sensors or diagnostics with advanced data science techniques can additionally help provide greater insight into complex plasma systems.
