Electron temperature and density measurement by Thomson scattering with a high repetition rate laser of 20 kHz on LHD

Abstract Thomson scattering measurements with a high-repetition-rate laser have commenced in the Large Helical Device. As an example of the fast phenomena captured by this diagnostic system, measurements at a 20 kHz repetition-rate in hydrogen pellet-injected plasmas are presented. Signal processing...
