Effects of plasma dielectric properties on Thomson scattering of millimetre waves in tokamak plasmas

Thomson scattering from a magnetized plasma is considered, taking into account the dielectric properties of the plasma. General results for the geometrical form factor are given in explicit form. The scattered power detectable by a heterodyne receiver is discussed and some numerical calculations are presented. The results are applied to the scattering of millimetre waves in tokamak plasmas near the electron-plasma and electron-cyclotron frequencies.
