Ion temperature measurement of a Tokamak plasma by collective Thomson scattering of D(2)O laser radiation
This report presents the results of ion temperature measurements in the Lausanne tokamak TCA obtained by scattering of 0.5 MW, 1.0 E-6 sec FIR pulses from an optically-pumped D(2)O laser, using a 12-channel Schottky-diode heterodyne receiver system of 8000 K DSB noise temperature. At plasma densities above 5x1.0_E-13/cm(3) the ion temperature could be obtained from a single laser shot. Results for different plasma conditions are presented and the influence of the magnetic field and the impurity content is discussed.
