Oscillations induced on the profile of a Gaussian CW CO2 laser beam by being transmitted through the TOSCA Tokamak plasma are confined within envelopes whose shapes are correctly predicted by theory, permitting plasma fluctuation intensity and wavelength to be deduced as functions of frequency by a curve fitting procedure. The analysis shows spontaneous density fluctuations integrated across the TOSCA minor diameter to be mainly transverse to the magnetic field, with intensity maxima between 40… CONTINUE READING
