An experimental investigation of current-driven ion sound turbulence in a collisionless magnetized plasma column is presented. Frequency and wave vector spectrum of the saturated instability are analyzed. The cross-power spectral density of probe signals shows that waves are localized in k space both in the electron drift direction and along the instability cone of angle theta=arc cos(c/sub s//v/sub d/) < or approx. =90/sup 0/. In spite of good plasma uniformity, azimuthal asymmetries in wave propagation are noticed. The self-consistent electron distribution function deviates from a shifted Maxwellian.
