Abstract

Broadband density fluctuations have been investigated in the TCA Tokamak by means of the phase contrast method using a CO-2 laser operating at 10.6 mu. This technique is well suited to the observation of large scale fluctuations. Correlation measurements between two detectors viewing different chords of the plasma cross- section show that more than half of the turbulence power is associated with wavenumbers smaller than 2 rad cm**- 1-.
