Development of Theory and Experimental Operational Framework for Coherent Thomson Scattering Grant uri icon


  • The proposed research aims to explore the feasibility and operational framework of a new diagnostic technique Coherent Thomson Scattering (CTS) for electrons and ions in low temperature plasma. This work will be performed in collaboration with the Princeton Collaborative Research Facility (PCRF) at Princeton Plasma Physics Laboratory. The technique will build on an established single shot diagnostic method Coherent Rayleigh-Brillouin scattering for neutrals. The proposed novel four wave mixing diagnostic technique CTS should allow for higher spatial resolution and lower detectable number densities for the electrons. Anticipated outcome of this project will be the development of the theoretical framework for Coherent Thomson Scattering as well as the specification of the appropriate operational experimental parameters for successful CTS implementation. Additionally, the mode of operation and the detection limits for a practical CTS experimental demonstration will be explored. Ultimately, successful experimental demonstration of CTS can be seen as transformative in a multitude of plasma physics areas, since it will allow for detailed, non-perturbative measurements of electron density and temperature, previously unattainable by other measurement techniques.
