Detailed studies of low-frequency microturbulence are presented. We utilize a unique multi-channel far-infrared (=1. 22 mm) laser scattering system capable of measuring the entire S (k_, ) spectrum during a single tokamak discharge. A statistical dispersion is unfolded for k_ which exhibits a phase velocity 3v₃₄ at low k_ with a distinct rolloff for k_>~9 cm^-1. In addition, a strong spatial asymmetry is observed in the k_ density-fluctuation distribution which reverses with toroidal current direction.
Brower et al. (1985) studied this question.
