Abstract
A high-speed Thomson scattering diagnostic using a pulse-burst laser is presented. Thomson scattering is a widely used plasma diagnostic that can be applied to the measurement of temperature and electron density in Hall thrusters, and the pulse-burst laser Thomson scattering system could be applied to the detailed characterization of instabilities in the plasmas. Data was collected at a rate of 10 kHz for an argon laboratory plasma, with calibration data obtained via Raman scattering. Results showed the viability of the pulse-burst laser application for high-speed Thomson scattering.
