Abstract

The signal-to-noise ratio (SNR) of ruby laser scattering measurements is studied as a function of the minor radius a, the laser parameters and the characteristics of the detection system. On a tokamak of JET-like dimensions, the SNR will be reduced at least by a factor of 8 with respect to its value on TFR. Possible improvements of present-day scattering devices are discussed.
