The power spectrum of plasma density fluctuations in the range of frequencies of drift waves has been investigated in the Princeton Large Torus tokamak. The results suggest that the observed fluctuations evolve to a strong nonlinear state, and therefore they emphasize the need for a complete nonlinear theory of drift waves in tokamaks to assess their effects on plasma transport.
E. Mazzucato (Mon,) studied this question.
