Thomson diffusion application : 1 Electron plasma monitor: A laser beam that passes through plasma interacts with free plasma electrons so that minute amount of the laser light is scattered from them. Tokamak a Configuration Variabile The TCV Thomson scattering setup. Laser light scattered by the plasma is observed at 25 points (black circles).
Thomson diffusion application: 2 Ultra short X-RAY SOURCE from Th. SCATTERING: the laser fotons are “classical” in the beam rest frame → Th. Sc.
Rayleigh diffusion application Rayleigh crosssection depends on density, i.e. on refraction index. More dense region deflects more a laser beam→ can be used to monitor the fluidodynamics of high temperature gases, macromolecules and a wide range of particles in solution. Flame development by R. imaging : laser beam modulated by R.D. In the gas n= refraction index N = gas density
