Analytical Approximations in the Theory of Relativistic Thomson Scattering for High Temperature Fusion Plasma
Abstract
The light scattering spectrum from a high temperature plasma is calculated for the second order in v/c (c=light speed) and the second order approximate formula is obtained from the calculation. The blue side shift of the peak derived from the second order approximate formula agrees well with that of the full relativistic spectrum for an electron temperature of several tens of kilo electronvolts and less. The second order apparent temperature and density are deduced with an accuracy of better than 8 percent in the range up to 20 keV and 100 keV for scattering angles θ{=}90^{°} and 50^{°}, respectively, by application of the leastsquare procedure.
